Peptides for Growth Hormone Deficiency
Unlike exogenous human growth hormone, GHRH analogs and ghrelin receptor agonists stimulate the pituitary to release GH in pulsatile, physiological patterns while preserving negative feedback.

How peptides help
Sermorelin (GHRH 1-29), CJC-1295 (modified GHRH), ipamorelin (selective ghrelin agonist), and MK-677 (oral ghrelin agonist) all elevate endogenous GH and downstream IGF-1. Tesamorelin is FDA approved specifically for HIV-associated lipodystrophy.

51 studies · GHRH Receptor Agonism
MK-677

75 studies · Oral Ghrelin Receptor Agonism
CJC-1295
PreliminaryL3Modified GHRH with extended half-life; limited human data.
24 studies · GHRH Receptor Agonism
Ipamorelin
PreliminaryL3Selective ghrelin agonist; commonly paired with CJC-1295.
33 studies · Ghrelin Receptor Agonism
State of the evidence
Tesamorelin has FDA-approval-level evidence for its specific indication. Other GHRH/GHRP peptides have limited large-scale human data; off-label anti-aging use is common but not FDA-endorsed.
Frequently asked
Are GHRH peptides safer than HGH?
They preserve the body's negative feedback on GH secretion, theoretically reducing risk of supraphysiologic GH levels. However, head-to-head safety data vs. recombinant HGH is limited.
