GHRP-6
Also known as: Growth Hormone Releasing Peptide-6, SKF-110679
The Original GHRP with Maximum Hunger
The first GHRP developed. Strong GH release with extreme hunger - more than any other GHRP. Best for hard-gainers who need to eat more.
How It Works
Simple Explanation
GHRP-6 was the first growth hormone releasing peptide developed. It powerfully stimulates GH release but also causes intense hunger - more than any other GHRP. Great for skinny guys trying to bulk up.
Technical Details
First-generation synthetic hexapeptide GHRP that binds to ghrelin receptors (GHSR) to stimulate pituitary GH release. Produces significant GH pulses but with pronounced ghrelin-like effects including dramatic appetite stimulation. Also elevates cortisol and prolactin more than newer GHRPs.
