What Are the Best Peptides for Growth Hormone?
This guide ranks the top research peptides for growth hormone based on current evidence, safety profiles, and practical considerations.
Each compound below has been evaluated on its mechanism of action, research depth, ease of use, and availability from quality sources.
#1: CJC-1295 — CJC-1295 (Modified GRF 1-29)
CJC-1295 is a Growth Hormone Releasing Hormone (GHRH) analog researched for increased growth hormone secretion, improved body composition, better sleep quality, enhanced recovery, anti-aging effects.
Mechanism: CJC-1295 binds to GHRH receptors on anterior pituitary somatotrophs, stimulating growth hormone synthesis and pulsatile secretion through the cAMP-PKA signaling cascade. The 'no DAC' version has a sho
Dosage: 100-300 mcg 1-3 times daily, typically before bed via subcutaneous injection. Cycle: 8-12 weeks, often paired with Ipamorelin.
Why it made the list: The 'no DAC' version is preferred over CJC-1295 DAC because it preserves natural pulsatile GH release rather than creating a sustained elevation that can desensitize receptors and suppress feedback loops. Read the full CJC-1295 guide →
#2: Ipamorelin — Ipamorelin
Ipamorelin is a Growth Hormone Secretagogue (GHS) / Ghrelin mimetic researched for growth hormone release, improved sleep, fat loss, muscle recovery, bone density support.
Mechanism: Ipamorelin selectively stimulates GH release by mimicking ghrelin at the GHS-R receptor on pituitary somatotrophs. Unlike other GHRPs (GHRP-2, GHRP-6, Hexarelin), it does not significantly increase co
Dosage: 200-300 mcg 2-3 times daily via subcutaneous injection. Cycle: 8-12 weeks, often stacked with CJC-1295.
Why it made the list: The most selective GH secretagogue available — the only GHRP that doesn't meaningfully raise cortisol, prolactin, or appetite at therapeutic doses, making it the safest entry point for GH optimization. Read the full Ipamorelin guide →
#3: GHRP-2 — Growth Hormone Releasing Peptide-2
GHRP-2 is a Growth hormone secretagogue, ghrelin receptor agonist researched for potent GH elevation, lean muscle mass gain, improved recovery, IGF-1 increases, increased appetite, bone density support.
Mechanism: Binds and activates the ghrelin receptor (GHS-R), a G-protein coupled receptor on pituitary somatotrophs. Triggers phospholipase C and inositol signaling cascades to stimulate GH secretion. Acts throu
Dosage: 100-300 mcg per injection 2-3 times daily on empty stomach via subcutaneous injection, intranasal spray. Cycle: 8-16 weeks with cycling protocols recommended.
Why it made the list: More potent GH release than Ipamorelin, but at the cost of cortisol, prolactin, and intense appetite stimulation — a classic potency vs. selectivity tradeoff. Read the full GHRP-2 guide →
#4: GHRP-6 — Growth Hormone Releasing Peptide-6
GHRP-6 is a Growth hormone secretagogue, ghrelin receptor agonist researched for potent GH elevation, muscle mass gain, recovery enhancement, IGF-1 increases, appetite stimulation, potential cardiac protection.
Mechanism: Binds GHS-R (ghrelin receptor) on somatotroph and hypothalamic neurons, activating GH secretion through phospholipase C cascade. Stimulates hypothalamic GHRH release and reduces somatostatin. Also act
Dosage: 100-300 mcg per injection 2-3 times daily on empty stomach via subcutaneous injection. Cycle: 8-16 weeks with periodic breaks to prevent receptor desensitization.
Why it made the list: The GHRP with the longest community track record (20+ years) and the most extreme appetite stimulation of any peptide — either a massive benefit or dealbreaker depending on your goals. Read the full GHRP-6 guide →
#5: Hexarelin — Hexapeptide Growth Hormone Secretagogue
Hexarelin is a Growth hormone secretagogue, synthetic GHRP researched for maximum GH elevation among GHRPs, enhanced muscle growth, superior recovery, direct cardiac protection (improved LVEF and cardiac output).
Mechanism: Activates GHS-R with high selectivity, triggering phospholipase C and inositol signaling for maximum GH secretion. Acts through three mechanisms: direct pituitary somatotroph stimulation, indirect GHR
Dosage: 100-200 mcg per injection 1-3 times daily via subcutaneous injection. Cycle: 8-16 weeks with breaks for receptor recovery.
Why it made the list: The most potent GH secretagogue available AND the only one with documented direct cardiac protection via CD36/GHSR-1a receptor activation — addressing both body composition and heart health. Read the full Hexarelin guide →
#6: MK-677 — Ibutamoren Mesylate
MK-677 is a Non-peptide ghrelin receptor agonist, growth hormone secretagogue researched for oral GH elevation (up to 97% increase), lean muscle mass gain, fat loss, improved sleep quality, enhanced recovery, bone density.
Mechanism: Selective non-peptide agonist of the ghrelin receptor (GHS-R1a) that increases GHRH production while simultaneously reducing somatostatin (GH inhibitor). Increases GH pulse amplitude and frequency, pr
Dosage: 10-25 mg daily once daily (usually before bed) via oral. Cycle: 8-16 weeks; minimum 10-week break between cycles.
Why it made the list: The only oral GH secretagogue producing clinically significant GH elevation without injections — uniquely accessible and practical compared to every other peptide that requires subcutaneous administration. Read the full MK-677 guide →
#7: Sermorelin — Growth Hormone-Releasing Hormone analog (GRF 1-29)
Sermorelin is a GHRH analog, growth hormone secretagogue researched for endogenous GH stimulation, lean mass gain, fat loss, IGF-1 elevation, improved recovery, bone density.
Mechanism: Binds GHRH receptors on anterior pituitary somatotrophs, activating cAMP-PKA signaling to stimulate GH synthesis and pulsatile secretion. Preserves natural GH feedback mechanisms — unlike exogenous GH
Dosage: 200-500 mcg daily once daily before bedtime via subcutaneous injection. Cycle: 12-24 weeks; adjust after 4-6 weeks based on IGF-1 levels.
Why it made the list: The only GHRH analog that preserves natural pulsatile GH secretion and feedback mechanisms — stimulates your body's own GH production rather than injecting exogenous hormone. Read the full Sermorelin guide →
#8: Tesamorelin — Synthetic GHRH analog (44 amino acid polypeptide)
Tesamorelin is a GHRH analog, growth hormone secretagogue researched for visceral fat reduction, body image improvement, metabolic restoration in HIV lipodystrophy.
Mechanism: Activates GHRH receptors on anterior pituitary somatotrophs via cAMP-PKA cascade. Elevated GH drives hepatic IGF-1 production, reducing visceral adiposity through enhanced lipolysis and reduced trunca
Dosage: 2 mg daily once daily via subcutaneous injection. Cycle: ongoing maintenance; demonstrated benefit to 12+ months.
Why it made the list: The most studied GHRH analog with the longest clinical track record — the only peptide with FDA approval specifically for lipodystrophy-associated visceral fat. Read the full Tesamorelin guide →
Can You Combine Multiple Growth Hormone Peptides?
Stacking complementary peptides for growth hormone is a common research approach. The key is combining compounds with different mechanisms to target multiple pathways without overlapping side effects.
See our stacking and cycling guide for principles on combining peptides safely.
How to Get Started
For beginners, start with a single, well-researched peptide rather than a complex stack. Use our dosing calculator for reconstitution math and our beginner's guide for step-by-step instructions.
Source from vendors with third-party COA testing — quality is the most important factor in achieving consistent research results.
Research-Grade Sourcing
If you're going to research Multiple, source matters. These are the suppliers WolveStack has vetted for purity and third-party testing.
