Compound brief
Evidence brief. Not treatment advice or a safety clearance. Last evidence update: September 2026.
The classic GHRH fragment. It asks an intact pituitary to release growth hormone. It is shorter than tesamorelin and it is not growth hormone itself.
A nightly forum schedule is Grade F in the protocol library. It is not tesamorelin and not an incretin.
GHRH(1-29) binds the pituitary GHRH receptor and the gland releases growth hormone if the somatotrophs are intact.
Hepatic IGF-1 is downstream of that growth-hormone pulse. The protocol library separates this fragment from tesamorelin and from exogenous growth hormone.
Forum themes are unverified. They do not outrank a study, and they are not a dose.
Nightly secretagogue pattern · unverified
Forums describe sermorelin as a nightly GHRH pulse and often pair it with a ghrelin peptide. The protocol library tags that pattern F. It is not tesamorelin and not a dose.
From the Catalyst protocol research library. Community schedules there are Grade F and are not a dose.
