What is the half-life of GHRP-6?

GHRP-6 has a half-life of Unknown, which is why it's typically administered As needed for optimal therapeutic effect.

How do I reconstitute GHRP-6?

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.

Growth Hormone

Preclinical

GHRP-6

Also known as: Growth Hormone Releasing Hexapeptide, His-D-Trp-Ala-Trp-D-Phe-Lys-NH2

Overview

Key Facts

Primary Goal: Stimulate growth hormone release for muscle growth and recovery

GHRP-6 is a potent growth hormone secretagogue that stimulates GH release through ghrelin receptor activation. Known for strong appetite stimulation, it supports muscle growth, enhanced recovery, and improved body composition through elevated growth hormone and IGF-1 levels.

Dosing Information

Half-Life

2-3 hours

Typical Dose

100-300 mcg

Frequency

2-3x daily

Cycle Length

8-16 weeks

Administration Routes:

subcutaneous

Benefits

Potent growth hormone release
Strong appetite stimulation for those seeking weight gain
Enhanced muscle growth and nitrogen retention
Improved recovery from training
Cytoprotective effects on cardiac tissue shown in research

Side Effects

Intense hunger within 20 minutes of administrationuncommonmild

Elevated cortisol and prolactin at higher dosesuncommonmild

Water retention and bloatinguncommonmild

Possible blood sugar fluctuationsuncommonmild

Mechanism of Action

Agonizes the GHS-R1a (ghrelin) receptor to stimulate GH release from the pituitary

Activates hypothalamic appetite centres via ghrelin pathway signaling

Increases gastric motility and gastric acid secretion

Triggers modest cortisol and prolactin co-release through non-selective receptor activation

Contraindications

Do not use this peptide if any of the following apply:

Obesity or conditions where appetite stimulation is undesirable
Active malignancy
Uncontrolled diabetes

Research Summary

Preclinical

GHRP-6 was one of the first synthetic GH secretagogues developed, extensively studied since the 1980s. It has been shown to produce robust, dose-dependent GH release, though with less selectivity than newer GHRPs. Preclinical research has also identified cardioprotective properties, with studies showing reduced infarct size in animal models of myocardial ischemia.
