Hexarelin's Cardiac Curiosity

Hexarelin's defining feature is potency — it produces a larger GH pulse than its GHRP cousins. But it also has a secondary, less-discussed property: it appears to bind cardiac receptors linked to the CD36 pathway, which has spawned a parallel line of research into possible cardioprotective effects.

That cardiac activity is distinct from the GH-releasing mechanism and remains preclinical, so members treat it as an interesting footnote rather than a validated benefit. Still, it's a reminder that peptides rarely act on a single target. The thread below is where members compare hexarelin to the other GHRPs on both potency and tolerability.
