Hexarelin produces the strongest GH pulse of any secretagogue peptide — louder than Ipamorelin, louder than GHRP-2, loud enough that researchers started checking other organs for side effects. What they found instead was a direct cardioprotective effect, independent of growth hormone entirely. The heart has its own receptors for this thing. The tradeoff: it also raises cortisol and prolactin more than the 'cleaner' secretagogues, which is the price of that bigger pulse.
What this means for you
Maximum GH pulse comes with maximum side effects too — cortisol and prolactin go up along with it. Not the beginner-friendly option.
The independent cardioprotective mechanism via non-GH receptors is the genuinely novel finding here, separate from the secretagogue effect.
Cardiac-specific ghrelin receptor binding that operates independently of GH release deserves its own dedicated research track.
A cardioprotective peptide that isn't primarily a GH drug is a different market entirely. Underexploited angle.
