GHRP-6 vs Tesamorelin

GHRP-6 vs Tesamorelin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

GHRP-6
Growth Hormone

GHRP-6 is the original growth hormone releasing peptide, discovered by Cyril Bowers in the 1970s through systematic study of enkephalin analogs. It was the first molecule to reveal the existence of the ghrelin receptor pathway, predating the discovery of ghrelin itself....

Tesamorelin
Growth Hormone

Tesamorelin is an FDA-approved synthetic GHRH analog (Egrifta) modified with trans-3-hexenoic acid to resist DPP-IV enzymatic cleavage, doubling its effective half-life. It restores pulsatile GH secretion and preferentially reduces visceral adipose tissue. Approved in 2010 for HI...
