Hexarelin vs Ipamorelin

Hexarelin vs Ipamorelin — 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....

Ipamorelin
Growth Hormone

Ipamorelin is a synthetic 5-amino acid growth hormone releasing peptide (GHRP) that selectively stimulates pituitary GH secretion without raising cortisol, prolactin, or appetite hormones. Acts on ghrelin receptors (GHSR-1a) for clean pulsatile GH release. Phase I/II research sta...
