Hexarelin vs Tesamorelin

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

Hexarelin
Growth Hormone

Hexarelin (Examorelin) is the most potent GHRP in clinical research, producing the largest GH pulses per microgram of any peptide in its class. Its methylated tryptophan residue (2-MeTrp) compared to GHRP-6 accounts for its increased potency....

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...
