Hexarelin vs. ipamorelin?

Hexarelin is more potent on GH release but less selective. Ipamorelin is generally preferred in modern protocols for that reason.

Key takeaways

At the reference preset of a 5mg Hexarelin vial reconstituted with 2 mL of bacteriostatic water, a 0.2mg dose measures 8 units on a U-100 insulin syringe.

Hexarelin is a synthetic hexapeptide GH secretagogue with greater potency than GHRP-6 but more pronounced effects on cortisol and prolactin compared with ipamorelin.

How to use this calculator›

1. Vial — the peptide amount printed on the vial, in milligrams.
2. BAC water — the bacteriostatic water added to the vial. More water means a lower concentration and a larger, easier-to-read draw.
3. Dose — the single dose being measured, in milligrams.
4. Syringe — the barrel being drawn into. The diagram rescales to that syringe, so the same dose sits at a different mark on a 0.3 mL barrel than on a U-100.
