What is the half-life of Hexarelin?

Hexarelin has a half-life of ~70 minutes, which is why it's typically administered 1-2 times daily for optimal therapeutic effect.

How do I reconstitute Hexarelin?

Add bacteriostatic water to the peptide vial slowly down the side. Typical reconstitution uses 2-3ml of water for a 5mg vial. Gently swirl, do not shake.

Overview

Key Facts

Primary Goal: A potent synthetic hexapeptide GH secretagogue and one of the strongest GHRPs available

A potent synthetic hexapeptide GH secretagogue and one of the strongest GHRPs available. It produces substantial GH release but is limited by rapid desensitization with continued use and notable effects on cortisol and prolactin. Half-Life ~70 minutes Typical Dose 100–200 mcg Frequency 1-2 times daily Cycle Length 4-8 weeks (with breaks due to desensitization)

Research Summary

Phase 3

Hexarelin has been studied in clinical trials for GH deficiency and cardiac recovery. It produces the most potent acute GH response among GHRPs but shows significant tachyphylaxis (desensitization) within 1-2 weeks of continuous use. Research on its cardioprotective effects is particularly noteworthy, with studies showing improved cardiac function in heart failure models independent of GH release.
