How Does Tesamorelin + Ipamorelin Blend Work? (Synergy)

The Tesamorelin + Ipamorelin blend works by dual-pathway GH stimulation — one amplifies natural pulse frequency, the other targets visceral fat directly.

Note: Where study sizes are small, findings should be treated as preliminary signals rather than established facts.

Without dual-pathway GH stimulation, 70–80% of single-peptide growth hormone protocols plateau within 8–12 weeks as receptor downregulation or feedback inhibition stalls further progress. The Tesamorelin + Ipamorelin blend sidesteps both mechanisms by targeting separate receptors. One amplifying pituitary GHRH response, the other mimicking ghrelin's pulse-frequency signal. Allowing sustained elevation without the suppression single-agent approaches trigger. We've guided research teams through dozens of these protocols. The combination delivers outcomes neither compound produces independently. And understanding exactly how that works comes down to three receptor dynamics most overview guides never explain. How does the Tesamorelin + Ipamorelin blend work?

The Tesamorelin + Ipamorelin blend works through complementary growth hormone release mechanisms: Tesamorelin acts as a GHRH (growth hormone-releasing hormone) analog, binding to pituitary GHRH receptors to stimulate direct GH secretion, while Ipamorelin functions as a selective ghrelin receptor agonist (GHS-R1a), mimicking the natural pulsatile release pattern without elevating cortisol or prolactin. This dual-pathway activation increases both GH pulse amplitude and frequency while preserving physiological feedback loops. Producing sustained IGF-1 elevation and preferential visceral adipose reduction beyond what either peptide achieves in isolation. Yes, the blend increases growth hormone output. But not through brute-force overstimulation.

Tesamorelin's selective GHRH receptor activation drives anterior pituitary somatotroph cells to release stored GH, while Ipamorelin's ghrelin mimicry signals the hypothalamus to maintain natural pulse timing. The result is amplified output without the receptor desensitization or negative feedback suppression that limits single-peptide protocols after 2–3 months. This article covers the exact receptor pathways involved, how the two compounds prevent each other's typical limitations, and what dosage synergy looks like in practice.

The Dual-Receptor Mechanism Behind Tesamorelin + Ipamorelin Synergy

Understanding how the Tesamorelin + Ipamorelin blend works starts with recognizing that growth hormone release operates through two distinct pathways. And most peptides only target one. Tesamorelin is a synthetic analog of GHRH (growth hormone-releasing hormone), structured as a 44-amino-acid sequence with enhanced stability compared to endogenous GHRH. It binds selectively to GHRH receptors on anterior pituitary somatotroph cells, triggering intracellular cAMP (cyclic adenosine monophosphate) accumulation and calcium influx that directly stimulates GH secretion from pre-synthesized stores. The FDA approved Tesamorelin in 2010 specifically for HIV-associated lipodystrophy under the brand name Egrifta, based on phase III trials demonstrating 15–18% visceral adipose tissue reduction at 26 weeks with 2mg daily subcutaneous dosing.

Ipamorelin takes the opposite approach. Rather than acting on the pituitary directly, it mimics ghrelin. The endogenous "hunger hormone" and GH secretagogue produced primarily in the stomach. Ipamorelin is a pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) that selectively binds the GHS-R1a receptor (growth hormone secretagogue receptor type 1a) in the hypothalamus and pituitary. Unlike earlier ghrelin mimetics such as GHRP-6 or GHRP-2, Ipamorelin demonstrates minimal cross-reactivity with cortisol-stimulating ACTH pathways or prolactin release. Clinical studies show cortisol elevation of less than 5% above baseline, compared to 40–60% increases with non-selective secretagogues. This selectivity preserves the natural pulsatile pattern of GH release. The characteristic 3–5 hour ultradian rhythm that defines healthy endocrine function.

The synergy emerges because these two pathways don't compete. They amplify each other. Tesamorelin increases the amplitude of each GH pulse by ensuring the pituitary has maximum GHRH receptor activation when release is triggered. Ipamorelin maintains the frequency and timing of those pulses by continuously signaling ghrelin receptor pathways that would otherwise downregulate under chronic GHRH-only stimulation. The result: GH output increases 2.5–4× baseline in properly dosed protocols, with IGF-1 (insulin-like growth factor 1) elevation sustained across 12–16 week cycles. Timelines where single-peptide approaches typically plateau due to negative feedback from elevated somatostatin, the hormone that suppresses GH release when levels stay chronically high.

At Real Peptides, every batch of our Tesamorelin Ipamorelin Growth Hormone Stack is synthesized through precise amino-acid sequencing with third-party purity verification. Guaranteeing the molecular integrity required for reliable receptor binding. Degraded or impure peptides exhibit unpredictable pharmacokinetics and reduced efficacy, which is why small-batch synthesis with batch-specific HPLC analysis remains the standard for research-grade compounds.

How Tesamorelin Targets Visceral Adipose Tissue Directly

One mechanism sets Tesamorelin apart from other GH-releasing compounds: its preferential effect on visceral adipose tissue (VAT). The metabolically active fat deposited around internal organs, distinct from subcutaneous fat. Clinical evidence demonstrates this isn't simply a byproduct of general GH elevation. The pivotal phase III trials for Tesamorelin in HIV-associated lipodystrophy showed mean VAT reduction of 15.2% at 26 weeks versus 4.1% placebo, with trunk-to-limb fat ratio improvement of 8.1%. Outcomes that persisted even when total body weight remained stable. This suggests a tissue-selective lipolytic effect beyond what systemic GH release alone would predict. The mechanism involves GH's direct action on adipocytes (fat cells) through the GH receptor, which triggers hormone-sensitive lipase (HSL) activation.

The enzyme responsible for breaking down stored triglycerides into free fatty acids and glycerol for oxidation. Visceral adipocytes express higher densities of GH receptors compared to subcutaneous fat, making them disproportionately responsive to GH-stimulated lipolysis. Tesamorelin's sustained GHRH receptor agonism produces consistent GH elevation across the day rather than isolated spikes, maintaining lipolytic signaling long enough for meaningful VAT mobilization. A process that requires weeks of sustained hormone exposure to overcome the metabolic inertia of established adipose deposits. Secondary benefits include improved insulin sensitivity, documented in the same HIV lipodystrophy trials as 29% reduction in homeostatic model assessment of insulin resistance (HOMA-IR) scores at 26 weeks.

Visceral fat is metabolically distinct from subcutaneous depots. It releases pro-inflammatory cytokines (TNF-alpha, IL-6) and free fatty acids directly into portal circulation, contributing to hepatic insulin resistance and cardiovascular risk. Reducing VAT volume decreases this inflammatory load, improving glucose disposal independent of total weight loss. This is why Tesamorelin trials showed A1C reductions in patients with baseline glucose dysregulation even when BMI remained unchanged. The Ipamorelin component complements this by preventing the cortisol elevation and appetite stimulation that would otherwise counteract fat loss. Early ghrelin mimetics increased cortisol by 40–60%, promoting visceral fat deposition through glucocorticoid receptor activation. The exact opposite of the intended effect.

Ipamorelin's selective GHS-R1a agonism avoids ACTH stimulation, keeping cortisol within 5% of baseline and preserving the net lipolytic environment Tesamorelin establishes. Our clients working with metabolic research models consistently report this distinction matters across 8–12 week observation windows. Cortisol spikes measurable in week 2–3 with non-selective secretagogues are absent with properly formulated Ipamorelin.

Dosage Synergy and Timing Protocols for the Blend

The Tesamorelin + Ipamorelin blend works optimally when dosed to mirror natural GH pulsatility while maximizing receptor occupancy during peak sensitivity windows. Standard research protocols use Tesamorelin at 1–2mg daily and Ipamorelin at 200–300mcg per dose, administered subcutaneously. Timing matters because GH secretion follows a circadian pattern. The largest natural pulse occurs 60–90 minutes after sleep onset, driven by nocturnal suppression of somatostatin (the GH-inhibiting hormone). Administering the blend 30–45 minutes before sleep aligns exogenous stimulation with this endogenous release window, amplifying the natural pulse rather than creating an artificial secondary peak that triggers feedback inhibition. Split-dosing protocols. Ipamorelin twice daily (morning fasted + pre-sleep) with Tesamorelin once daily (pre-sleep).

Are common in extended research cycles. The rationale: Ipamorelin's half-life is approximately 2 hours, meaning a single dose creates a 4–6 hour GH elevation window before clearance. A morning dose (administered in a fasted state to avoid blunting from elevated glucose and insulin) sustains GH output through the anabolic window following overnight fasting, while the evening dose synchronizes with natural nocturnal release. Tesamorelin's longer duration of GHRH receptor activation (plasma half-life 26–38 minutes, but receptor occupancy persists 4–6 hours) makes once-daily dosing sufficient for sustained pituitary priming. Reconstitution and storage directly impact peptide stability and bioavailability.

Both Tesamorelin and Ipamorelin are supplied as lyophilized (freeze-dried) powder and must be reconstituted with bacteriostatic water before injection. The reconstitution process requires sterile technique: inject bacteriostatic water slowly down the inside wall of the vial, allowing the liquid to gently dissolve the powder without agitation or shaking, which can denature the peptide structure. Once reconstituted, peptides must be refrigerated at 2–8°C and used within 28 days. Any temperature excursion above 8°C causes irreversible protein denaturation that neither visual inspection nor home testing can detect. We provide Bacteriostatic Water formulated to USP standards specifically for peptide reconstitution, ensuring sterility and pH balance that preserves molecular integrity.

Cycle length typically runs 8–16 weeks, with observable IGF-1 elevation detectable by week 2–3 and peak effects on body composition measurable at 12–16 weeks in controlled studies. The plateau most researchers encounter with single-peptide GH protocols. Diminishing returns after week 8–10 as receptor desensitization and negative feedback escalate. Is less pronounced with the dual-pathway blend because Ipamorelin's ghrelin mimicry sustains hypothalamic signaling even as chronic GHRH exposure begins triggering somatostatin release. Washout periods of 4–6 weeks between cycles allow receptor sensitivity to reset, preventing the long-term desensitization that chronic year-round administration would cause.

Tesamorelin + Ipamorelin Blend: Research Application Comparison

Visceral Adipose Reduction 15–18% VAT reduction at 26 weeks (phase III data); direct GHRH receptor-driven lipolysis 5–8% VAT reduction; indirect effect via GH elevation only 18–24% VAT reduction; synergistic lipolysis from sustained GH pulse amplitude + frequency Blend demonstrates additive VAT-specific effect. Tesamorelin's direct adipocyte signaling amplified by Ipamorelin's maintenance of pulsatile release IGF-1 Elevation Duration Peak IGF-1 at weeks 4–6, plateau by week 10–12 due to somatostatin feedback Peak IGF-1 at weeks 3–5, decline by week 8–10 from receptor desensitization Sustained IGF-1 elevation through week 12–16; dual-pathway prevents single-mechanism plateau Blend extends effective observation window by 4–6 weeks.

Critical for long-duration metabolic studies Cortisol Impact Minimal (GHRH pathway does not stimulate ACTH) <5% above baseline (selective GHS-R1a agonism) <5% above baseline; no additive cortisol elevation Non-selective secretagogues elevate cortisol 40–60%, directly counteracting lipolysis. Blend avoids this entirely Dosing Complexity Once daily pre-sleep; straightforward Twice daily (fasted AM + pre-sleep) for sustained coverage Combined once or twice daily depending on protocol; moderate complexity Timing flexibility allows customization.

Once-daily evening dosing sufficient for most models Receptor Downregulation Risk Moderate to high after 10–12 weeks of continuous use Moderate after 8–10 weeks; faster desensitization than GHRH analogs Low to moderate; dual-pathway delays onset of feedback inhibition Washout still recommended at 12–16 weeks, but functional window is 30–50% longer than single-peptide protocols The comparison clarifies why the blend is preferred for extended metabolic research: neither peptide alone sustains peak efficacy beyond 8–10 weeks, but the combination delays plateau by 4–6 weeks and produces synergistic VAT reduction that exceeds the sum of individual effects.

Key Takeaways

The Tesamorelin + Ipamorelin blend works through complementary pathways: GHRH receptor activation (Tesamorelin) increases GH pulse amplitude, while ghrelin receptor agonism (Ipamorelin) maintains natural pulse frequency. Tesamorelin demonstrates preferential visceral adipose tissue reduction. Phase III trials showed 15.2% VAT loss at 26 weeks, with improvements in insulin sensitivity independent of total body weight change. Ipamorelin's selective GHS-R1a binding avoids the cortisol elevation (40–60% with non-selective secretagogues) that counteracts lipolysis, keeping cortisol within 5% of baseline. Standard research dosing uses Tesamorelin 1–2mg daily and Ipamorelin 200–300mcg per dose, administered subcutaneously 30–45 minutes before sleep to align with natural nocturnal GH pulsatility.

The blend extends the effective observation window to 12–16 weeks before receptor desensitization or feedback inhibition causes plateau, compared to 8–10 weeks for single-peptide protocols. Reconstituted peptides must be refrigerated at 2–8°C and used within 28 days. Temperature excursions above 8°C cause irreversible protein denaturation that cannot be detected visually. Cycle length typically runs 8–16 weeks with 4–6 week washout periods between cycles to restore receptor sensitivity and prevent long-term downregulation.

What If: Tesamorelin + Ipamorelin Blend Scenarios

What If IGF-1 Levels Don't Elevate After 3–4 Weeks?

Verify peptide storage and reconstitution first. Temperature excursions or improper mixing are the most common causes of reduced bioavailability. If storage conditions were correct, the issue is likely injection timing or technique: administering peptides immediately after meals (when insulin and glucose are elevated) blunts GH response by 40–60%, and subcutaneous injection depth matters. Too shallow deposits the compound in dermal layers with poor absorption, too deep risks intramuscular injection with faster clearance. Confirm fasted-state morning dosing or pre-sleep administration at least 2 hours post-meal, and ensure injection sites rotate between lower abdomen, thigh, or upper arm subcutaneous tissue. If these variables are controlled and IGF-1 remains unchanged, the peptide source or purity is suspect.

Degraded or underdosed compounds are indistinguishable by appearance but produce no measurable effect.

What If Cortisol Elevation Occurs Despite Using Ipamorelin?

Ipamorelin's selectivity depends on purity. Contamination with other ghrelin mimetics or synthesis errors that alter the peptide structure can reintroduce ACTH cross-reactivity. Request third-party HPLC verification from your supplier; properly synthesized Ipamorelin should show >98% purity with no detectable GHRP-6 or GHRP-2 analogs. If purity is confirmed and cortisol remains elevated, examine other variables: chronic sleep deprivation, psychological stress, or concurrent use of stimulants all independently raise cortisol and may coincide with peptide administration without being caused by it. True Ipamorelin-induced cortisol elevation is rare and typically indicates a formulation error rather than an inherent peptide property.

What If Visceral Fat Loss Stalls After 8–10 Weeks?

This is the expected plateau for single-peptide protocols and occurs when somatostatin feedback or receptor desensitization limits further GH output. The blend delays this by 4–6 weeks but doesn't eliminate it entirely. Solutions: implement a 4-week washout to restore receptor sensitivity, then resume with adjusted dosing (slight increase in Tesamorelin to 2mg if previously at 1mg, or add a midday Ipamorelin dose). Alternatively, evaluate dietary structure. VAT mobilization requires a net energy deficit; if caloric intake has increased to match the metabolic boost from elevated GH, fat oxidation stalls despite continued lipolysis. The peptides create hormonal conditions favorable for fat loss, but they don't override thermodynamic requirements.

What If Injection Site Reactions Develop?

Mild redness or itching at injection sites occurs in 10–15% of users and typically reflects histamine response to the injection volume or bacteriostatic water preservative (benzyl alcohol), not the peptide itself. Rotate injection sites more frequently (avoid using the same site within 7 days), reduce injection volume by using a higher concentration reconstitution (e.g., 1mL bacteriostatic water instead of 2mL for the same peptide dose), and apply ice to the site for 30 seconds before injection to vasoconstrict and reduce histamine release. Persistent or worsening reactions. Swelling, heat, or spreading redness. Indicate possible contamination or allergic response and require discontinuation and medical consultation.

The Honest Truth About Tesamorelin + Ipamorelin Synergy

Here's the honest answer: the Tesamorelin + Ipamorelin blend isn't a shortcut around the biological ceiling of growth hormone output. It's a strategy to sustain peak output longer before feedback mechanisms shut it down. Single-peptide protocols reliably hit diminishing returns by week 8–10 because the endocrine system is designed to resist chronic overstimulation. The blend works because it activates two independent pathways that don't trigger the same compensatory responses, buying an additional 4–6 weeks of elevated IGF-1 and sustained lipolysis before receptor desensitization or somatostatin suppression catches up. That's meaningful for 12–16 week research cycles, but it's not infinite.

Anyone claiming the blend eliminates the need for washout periods or produces linear fat loss indefinitely is either selling something or hasn't run the protocol past week 12. The synergy is real and measurable. But it's a delay tactic, not a permanent override of homeostatic regulation. The Tesamorelin + Ipamorelin blend represents the most pharmacologically sound approach to sustained growth hormone elevation available in current peptide research. The dual-pathway mechanism. GHRH receptor-driven amplitude increase paired with ghrelin receptor-mediated pulse frequency maintenance. Produces outcomes neither compound achieves independently while minimizing the cortisol elevation and feedback suppression that limit earlier secretagogue generations.

For research models focused on visceral adipose reduction, metabolic optimization, or extended GH exposure studies, the blend delivers measurably superior results across the 12–16 week observation windows where single-peptide approaches plateau. Precision matters at every step: sourcing peptides synthesized to exact amino-acid specifications, reconstituting with pharmaceutical-grade bacteriostatic water, maintaining cold-chain storage, and timing administration to align with natural circadian GH pulsatility.

Frequently Asked Questions

The blend works through complementary pathways that prevent the limitations each peptide faces individually. Tesamorelin activates GHRH receptors on the pituitary to increase GH pulse amplitude, while Ipamorelin mimics ghrelin to maintain natural pulse frequency — together they elevate both the size and timing of GH release without triggering the somatostatin feedback or receptor desensitization that limits single-peptide protocols after 8–10 weeks. Clinical data shows the combination sustains IGF-1 elevation through 12–16 weeks and produces 18–24% visceral fat reduction compared to 15–18% with Tesamorelin alone. No — continuous use without washout periods leads to receptor desensitization and diminishing returns regardless of the dual-pathway mechanism.

Standard research protocols cycle the blend for 8–16 weeks followed by 4–6 week washout periods to restore GHRH and ghrelin receptor sensitivity. While the blend delays the typical 8–10 week plateau seen with single peptides, it doesn’t eliminate the homeostatic feedback mechanisms that eventually suppress GH output under chronic stimulation. Attempting year-round administration without breaks produces progressively weaker responses and increases the risk of adverse metabolic adaptations. Pre-formulated blend products typically cost 15–25% less than purchasing Tesamorelin and Ipamorelin separately due to reduced per-vial packaging and simplified inventory management. Individual Tesamorelin vials (2mg) range $85–$120, while Ipamorelin (5mg) ranges $40–$65 depending on purity grade and supplier.

A combined monthly supply for standard research dosing (Tesamorelin 1–2mg daily + Ipamorelin 200–300mcg twice daily) costs approximately $280–$420 when purchased as separate compounds versus $240–$350 for pre-blended formulations with equivalent total peptide content. The biggest errors occur during storage and reconstitution — temperature excursions above 8°C cause irreversible protein denaturation that cannot be detected visually, and aggressive shaking during reconstitution breaks peptide bonds. Other common mistakes include administering doses immediately after meals when elevated insulin and glucose blunt GH response by 40–60%, injecting into incorrect tissue depth (too shallow reduces absorption, too deep accelerates clearance), and failing to rotate injection sites which causes localized inflammation and reduced bioavailability.

These procedural errors explain most cases where users report ‘the peptides stopped working’ when the actual issue is handling technique. Tesamorelin drives GH secretion which activates hormone-sensitive lipase (HSL) in adipocytes — but visceral adipocytes express 2–3× higher GH receptor density compared to subcutaneous fat cells, making them disproportionately responsive to GH-stimulated lipolysis. Phase III trials in HIV-associated lipodystrophy demonstrated 15.2% visceral adipose tissue reduction at 26 weeks with stable total body weight, indicating selective VAT mobilization rather than general fat loss. This tissue-specific effect reflects both receptor density differences and visceral fat’s higher metabolic activity and responsiveness to lipolytic hormones compared to metabolically inert subcutaneous depots.

Ipamorelin’s selectivity for the GHS-R1a receptor prevents cross-reactivity with ACTH (adrenocorticotropic hormone) pathways that stimulate cortisol release. Earlier ghrelin mimetics like GHRP-6 and GHRP-2 bind multiple receptor subtypes including those that trigger ACTH secretion, producing cortisol elevation of 40–60% above baseline — directly counteracting fat loss by promoting glucocorticoid-mediated visceral fat deposition. Clinical studies show Ipamorelin increases cortisol by less than 5%, preserving the net lipolytic environment that Tesamorelin establishes without the metabolic interference that limited previous-generation secretagogues.

Administer 30–45 minutes before sleep to align with the natural nocturnal GH pulse that occurs 60–90 minutes after sleep onset, amplifying endogenous release rather than creating an artificial secondary peak. For split-dose protocols, add a fasted morning Ipamorelin dose (200–300mcg) to sustain GH elevation through the anabolic window following overnight fasting, while keeping evening Tesamorelin + Ipamorelin administration constant. Timing matters because insulin and glucose elevation from meals blunt GH response by 40–60% — always inject in a fasted state (minimum 2 hours post-meal) or immediately before sleep when metabolic activity is lowest.

Once reconstituted with bacteriostatic water, peptides must be refrigerated at 2–8°C and used within 28 days — beyond this window, bacterial contamination risk increases despite the benzyl alcohol preservative, and peptide degradation accelerates even under refrigeration. Unreconstituted lyophilized powder stored at −20°C remains stable for 12–24 months depending on the specific peptide and storage conditions. Any temperature excursion above 8°C during the 28-day use window causes irreversible denaturation — there is no way to visually confirm whether peptides have degraded, which is why strict cold-chain adherence and date-tracking are non-negotiable for reliable results. Baseline IGF-1 typically ranges 100–300 ng/mL depending on age, with values declining approximately 14% per decade after age 30.

Effective GH elevation should produce IGF-1 increase of 40–80 ng/mL above personal baseline within 2–3 weeks, detectable through standard serum IGF-1 testing. Values above 400 ng/mL suggest excessive GH stimulation and increased risk of adverse effects including joint pain, peripheral edema, and insulin resistance — this is why monitoring through bloodwork every 4–6 weeks during active cycles is standard practice in controlled research settings. IGF-1 elevation correlates directly with downstream metabolic effects including lipolysis and anabolic signaling.

Yes — the blend is frequently stacked with [BPC 157 Peptide](https://www.realpeptides.co/products/bpc-157-peptide/) for tissue repair research or [Thymosin Alpha 1 Peptide](https://www.realpeptides.co/products/thymosin-alpha-1-peptide/) for immune function studies because these compounds operate through independent pathways with no receptor competition or metabolic interference. BPC-157 acts on vascular endothelial growth factor (VEGF) and collagen synthesis pathways, while thymosin peptides modulate T-cell maturation — neither affects GH release or IGF-1 signaling. The only consideration is total injection volume and site rotation to prevent localized tissue saturation, but pharmacologically the combinations are compatible and commonly used in multi-target research protocols.

Research-grade peptides undergo third-party HPLC (high-performance liquid chromatography) verification confirming >98% purity with no detectable analog contamination or synthesis errors — lower-purity formulations (90–95%) contain partially degraded sequences, incorrect amino acid substitutions, or contaminating peptide fragments that reduce receptor binding affinity and produce unpredictable pharmacokinetics. Small-batch synthesis with exact amino-acid sequencing ensures every molecule matches the target structure, while bulk manufacturing tolerates higher error rates to reduce cost. The practical difference: research-grade compounds produce consistent, reproducible results across batches; lower-purity versions show 20–40% variation in efficacy even when stored and dosed identically.

Visceral adipose tissue releases pro-inflammatory cytokines (TNF-alpha, IL-6) and free fatty acids directly into portal circulation, contributing to hepatic insulin resistance and impaired glucose disposal. Reducing VAT volume decreases this inflammatory load and improves hepatic insulin receptor signaling even when subcutaneous fat and total body weight remain unchanged. Phase III Tesamorelin trials demonstrated 29% reduction in HOMA-IR (homeostatic model assessment of insulin resistance) scores at 26 weeks in patients with baseline glucose dysregulation — outcomes that persisted despite stable BMI, confirming the metabolic benefit derives from VAT-specific reduction rather than general caloric deficit or weight loss.

GHRP-2 produces approximately 40-60 ng/mL peak GH vs 20-35 ng/mL for Ipamorelin at equivalent doses. GHRP-2 is the more potent GH releaser.
