GHRP-2 and GHRP-6
They release growth hormone and make you hungry. No muscle trial.
Grade B: Some human proof
Small, early or mixed results in people.
The grade is for the use people talk about, not for every use. Filed under: Growth hormone boosters.
How it works
Lab-made peptides that hit the receptor for ghrelin, the hunger hormone. That same receptor releases growth hormone.
How it was given in studies
GHRP-2 was given as a slow drip under the skin, in a lab study of 19 people.
This is what the studies did. It is not a how-to. Source: GHRP-2 and food intake. Obesity, 2006.
What studies saw
In a double-blind study of 19 adults, GHRP-2 raised growth hormone, and people ate up to a third more at a buffet meal. We found no trial of muscle, fat or strength.
The trade-off
FDA flags possible immune reactions for both. For GHRP-6 it lists concerns about cortisol and blood sugar. For GHRP-2 it notes reports of serious harm, with the cause not established.
When it showed up, in studies
Growth hormone and hunger rise within hours.
No human timeline for muscle or fat.
