GHRP-2 vs Epitalon
Both GHRP-2 and Epitalon are used for anti-aging. Here's how their evidence, dosing, and regulatory status actually compare.
GHRP-2
Evidence BGrowth Hormone Releasing Peptide 2
A potent synthetic ghrelin-mimetic GH secretagogue. Drives strong GH spikes but raises cortisol and prolactin more than newer alternatives like Ipamorelin.
