GHRP-2 vs Hexarelin
Both GHRP-2 and Hexarelin are used for growth-hormone. 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.

Evidence BHexarelin (HEX)
The strongest GH-releasing hexapeptide and one of the few peptides with documented direct cardiac benefits in animal models. Tachyphylaxis (diminished response over time) limits long-term use.
