GHRP-6
Shop GHRP-6Also called: GHRP 6 & CJC 1295 Peptide Mix, Growth Hormone Secretagogue Peptide-6
GHRP-6 is a man-made peptide made of six small building blocks. Its full name is Growth Hormone Releasing Peptide-6. It is not an approved medicine. It is sold only for lab research, and some scientists and study labs buy it for experiments.
In lab tests, GHRP-6 turns on a switch called the ghrelin receptor. Ghrelin is a natural body chemical that makes you feel hungry. When this switch is turned on, a gland at the base of the brain lets out growth hormone in bursts. Scientists study this to learn how the body controls growth, hunger, and how it uses fat and sugar.
GHRP-6 is not approved for people to use. Most of what we know comes from animal and test-tube studies, not careful human trials. We do not fully know if it is safe. It may raise hunger, and long-term effects are unknown. Anyone with health questions should talk to a real doctor, not use research chemicals.

mg vs mcg: one milligram (mg) equals 1,000 micrograms (mcg) — multiply by 1,000 going from mg to mcg, divide by 1,000 going from mcg to mg. Mixing the two up is a thousand-fold dosing error: 1 mg taken instead of 1 mcg is a 1,000× overdose; 1 mcg instead of 1 mg is a 1,000× underdose. Always double-check the unit label and the decimal place.

Technical Details (sequence & mechanism — click to expand)
Mechanism of Action
GHRP-6 is a synthetic hexapeptide ghrelin-receptor (GHSR-1a) agonist that stimulates endogenous GH release and produces notably strong appetite stimulation (orexigenic), mimicking ghrelin. Preclinical work also shows cardioprotective effects. It is not FDA-approved.

UFC Athlete, Mendes, Receives Sanction for Anti-Doping Policy Violation
UFC featherweight Chad Mendes, 31, tested positive for GHRP-6 (Growth Hormone-Releasing Hexapeptide) from an out-of-competition urine collection on May 17, 2016 and accepted a two-year sanction. USADA states the peptide is prohibited at all times under the UFC/WADA anti-doping rules (class S2, peptide hormones). His ineligibility began June 10, 2016, with results from May 17, 2016 onward disqualified.
Certain Bulk Drug Substances for Use in Compounding that May Present Significant Safety Risks
FDA's running list of bulk drug substances that present significant safety risks in compounding names GHRP-2, GHRP-6, ipamorelin acetate, CJC-1295 and AOD-9604. GHRP-2 and GHRP-6 were added to the 503B risk list on September 29, 2023 over immunogenicity concerns, and FDA notes serious adverse events for CJC-1295 (increased heart rate, systemic vasodilatory reactions). The list confirms these peptides are treated by FDA as unsafe-for-compounding substances.
Tailor Made Compounding LLC
FDA warned Tailor Made Compounding LLC (Nicholasville, KY) after a 2018 inspection found it compounded drug products with bulk substances ineligible for 503A exemptions. The letter explicitly lists the compounded substances: Follistatin, GHRP-2, GHRP-6, AOD 9604, BPC 157, Bremelanotide (PT-141), Cerebrolysin, DSIP, Epitalon, GHK-Cu, Ipamorelin, LL-37, Melanotan II, Selank, Semax, and CJC 1295, among others. The firm was cited for insanitary aseptic processing (adulteration), unapproved new drugs, and misbranding, and removed GHRP-2 and GHRP-6 from its formulary in response.
