Sermorelin
29-amino acid GHRH analog. Stimulates pulsatile endogenous growth hormone release; gentler than synthetic GH.
GHRH(1-29). Originally FDA-approved as Geref for pediatric GH deficiency (withdrawn 2008 commercially). Now produced via 503A compounding for adult anti-aging clinics. Triggers physiologic pulsatile GH release rather than the supraphysiologic spike of recombinant HGH.
Original Geref withdrawn for commercial reasons, not safety. Compounded sermorelin quality varies; verify pharmacy accreditation (PCAB / NABP).
