GHRP-6
THE HUNGER DRIVER
Growth Hormone Releasing Peptide-6
GHRP-6 was one of the first growth hormone releasing peptides developed. It triggers strong GH release and is known for significantly increasing appetite, often called "hunger on steroids." This makes it ideal for bulking phases but challenging for those watching their food intake. It also promotes muscle growth, fat loss, and tissue repair.

Quick Answers About GHRP-6
Is GHRP-6 FDA approved?
No. This profile records GHRP-6 as not FDA approved and for research use only.
More context
Review the regulatory and source details on this page for the current context.
What dose does The Peptide App Clinical Team recommend for GHRP-6?
Dose: 100-300 mcg 2-3 times daily.
More context
Schedule: eod. Cycle: 8-12 weeks on, 4 weeks off. This is clinical-team guidance for reference and does not replace individualized instructions from a licensed clinician.

Review the GHRP-6 research sourcesWhat are the side effects of GHRP-6?
Reported side effects of GHRP-6 include Intense hunger, Water retention, Injection site reactions, and Potential cortisol/prolactin elevation.
More context
They are reported or occasional reactions, not a prediction of what any one person will experience.
Is GHRP-6 safe?
GHRP-6 has an editorial safety grade of B (Good Safety).
More context
Generally well-tolerated. Stronger appetite effects than other GHRPs. Safety depends on dose, sourcing, health history and medical supervision, so this page does not call it safe for personal use.
Which proteins did EGF plus GHRP6 change in animal stroke models?
In a rat model of acute ischemic stroke, EGF combined with GHRP6 modulated 40 proteins at 3 hours and 223 proteins at 24 hours after treatment in the ischemic penumbra. In these rats, anti-apoptotic and mitochondrial proteins were modulated in the ischemic penumbra after EGF plus GHRP6 treatment. At 24 hours after treatment in rats, proteins linked to reactive oxygen species detoxification, heat shock factor 1 activation, and negative regulation of cellular hypoxia response were significantly modulated by GHRP6 combined with EGF.
Studied Effects & Mechanisms
Ghrelin Mimetic
Strongly activates ghrelin receptors for GH release
GH Secretion
Triggers powerful growth hormone pulses
Appetite Surge
Produces intense hunger through hypothalamic activation
Origins of the GHRP research series
GHRP-6 is a synthetic chain of six amino acids. Bowers and colleagues described its sequence in a 1984 paper as His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. The D designations identify the configuration of particular amino-acid residues, while NH2 denotes an amidated end. The paper is part of the early laboratory history of the growth-hormone-releasing peptide family.

GHRP-6 product testing and COAs
We found certificates from some of the GHRP-6 vendors we track. Based on the certificates our crawler found; vendors may publish more than we index. Research on this page describes the molecule. Vendor certificates concern particular market samples or batches; they do not change the research evidence or establish clinical safety, sterility, or suitability for use.
