Plain English
- What it is
- GHRP-1 is a lab-made peptide (a short chain of amino acids) in the growth hormone releasing peptide family. It nudges the body to release more of its own growth hormone. It is a research chemical, not an approved medicine, and it is the least studied of its group compared with the better-known GHRP-2 and GHRP-6.
- What people use it for
- In the peptide community it is the lesser-used cousin of GHRP-2 and GHRP-6. People who try it are usually sampling growth hormone peptides they have not used before, and most circle back to ipamorelin or GHRP-2.
- What the science shows
- Published research is thin and mostly old. The main human work comes from small, older studies showing it can briefly raise growth hormone levels. There is no modern, detailed study of how it behaves in the body or whether it helps any health goal, unlike some related peptides.
- The catch
- It is not FDA-approved, and the FDA has flagged this class of peptides as bulk substances that may carry significant safety risks when compounded. It is also banned in sport at all times by the World Anti-Doping Agency. Because the evidence is so limited, its long-term safety in people is not well understood.
Reference summary
Published literature on GHRP-1 is limited to older preclinical and small-human GH-response studies. There is no modern PK/PD or outcome program comparable to GHRP-2, GHRP-6, or ipamorelin.
Regulatory and posture
- Categories
- GH Release
- Aliases
- Growth hormone releasing peptide 1, SKF-108,922
- Evidence posture
- preclinical - Older preclinical and small-human GH-response data only. Less characterized than GHRP-2, GHRP-6, or ipamorelin.
- Regulatory status
- No FDA-approved GHRP-1 drug label. FDA lists GHRP-class peptides among bulk drug substances with safety-risk concerns for compounding. GHRP-1 is less characterized than GHRP-2 or GHRP-6 and is rarely studied in modern literature.
