Attribute
Hexarelin
GHRP-6
Mechanism
Potent GHRP; strong GH release with modest cortisol/prolactin activity.
First-generation GHRP; strong ghrelin activity with pronounced appetite stimulation.

Indications
- Body composition
- Recovery
- Body composition with appetite support
- Recovery
Strengths
- Highest per-dose GH release among GHRPs
- Appetite stimulation useful for underweight patients
Cautions
- Faster receptor desensitization
- Mild cortisol/prolactin bump
- Cortisol and prolactin elevation
- Appetite unwanted in weight-loss protocols
Choose Hexarelin when
Patient needs maximum GH pulse magnitude and can tolerate faster desensitization.
Wholesale Hexarelin →Choose GHRP-6 when
Patient needs appetite stimulation alongside GH (e.g. underweight or wasting).
Wholesale GHRP-6 →FAQs
- Are these still used clinically?
- Less than ipamorelin, which offers a cleaner side-effect profile. Reserved for specific goals.
- Do they cause prolactin spikes?
- Both can. Ipamorelin is preferred when a clean cortisol/prolactin profile is required.
