Dosage protocol · Growth Hormone & Performance
GHRP-6 2 mg
Typical daily range: 300–900 mcg total (split into 3 doses with gradual titration).
- Reconstitute: Add 3.0 mL bacteriostatic water → ~0.67 mg/mL concentration.
- Typical daily range: 300–900 mcg total (split into 3 doses with gradual titration).
- Easy measuring: At 0.67 mg/mL, 1 unit = 0.01 mL ≈ 6.67 mcg on a U-100 insulin syringe.
- Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and use within 7 days.

How it works
GHRP-6, or growth hormone-releasing peptide-6, is a synthetic hexapeptide -- a chain of six amino acids -- studied for its ability to trigger growth hormone (GH) release.[1] It belongs to a class of compounds called GH secretagogues, which work differently from recombinant human growth hormone (somatropin): rather than replacing GH directly, GHRP-6 is designed to stimulate the body's own pituitary gland to release it.[6]
GHRP-6 is a research compound. It has no FDA-approved prescribing information, labeled indication, or approved dosage for medical treatment in the United States.[3]
Benefits & side effects
Human research on GHRP-6 is best described as early clinical physiology work rather than outcome-focused trials. Older studies examined whether GHRP-6 could stimulate GH secretion, how that response changed with age, obesity, or co-administration of GHRH, and how it compared with related secretagogues -- but these were largely small, short-term studies built around hormone sampling, not patient-centered endpoints like strength, body composition, or recovery.[6][7]
Preclinical work, including the original receptor-cloning studies and animal models of ghrelin biology, supports the mechanism but cannot establish human benefit. Claims commonly seen online -- that GHRP-6 builds muscle, reverses aging, improves recovery, or has minimal side effects -- go well beyond what any published study has demonstrated. For comparison, a different oral GH secretagogue, macimorelin, does have FDA-approved labeling, but only for diagnosing adult growth hormone deficiency in a clinical setting; that approval does not extend to GHRP-6.[12]
