Hexarelin

GHRP — Potent

Most potent of the classic GHRPs — strong GH pulse plus direct cardiac/CD36 effects.

Hexarelin is the hardest-hitting of the old-school GHRPs — it produces the biggest single GH pulse of the group and has its own direct effects on heart tissue (via the CD36 receptor) that the others don't. The catch is rapid desensitisation: within a few weeks the receptor stops responding, so it has to be pulsed in short bursts rather than run continuously. It's a specialist tool — reach for it when you want a strong, short GH kick or are specifically interested in its cardioprotective signalling, not as a daily driver.
