GHRP-2
What Is GHRP-2?
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates growth hormone release through the ghrelin receptor. It provides reliable GH release and is popular for anti-aging, muscle building, and fat loss.
GHRP-2 Research & Studies
01 GHRP-2 attenuates muscle atrophy markers in myocytes ▸
GHRP-2 directly reduces Atrogin-1 and MuRF1 mRNA levels in muscle cells through ghrelin receptor activation, potentially preventing muscle degradation.
View Study (ScienceDirect)02 Identification of GHRP-2 in nutritional supplements ▸
GHRP-2 was detected and quantified in over-the-counter supplements, raising performance enhancement concerns in elite sports contexts.
View Study (Wiley Analytical Science)03 GHRP-2 increases food intake in healthy men ▸
Subcutaneous GHRP-2 administration increases appetite in humans similarly to ghrelin, providing insights into eating behavior mechanisms.
View Study (Oxford Academic)04 GHRP-2 vs GHRP-6 growth hormone release comparison ▸
Both peptides stimulate GH release from rat pituitary cells through identical receptors despite structural differences.
View Study (ScienceDirect)05 GHRP-2 and GHRH synergistic GH release in swine ▸
Combined GHRP-2 and GHRH administration produces synergistic growth hormone stimulation, diminishing with repeated dosing.
View Study (J-Stage)06 GHRP-2 reduces oxidative stress but not atherosclerosis ▸
GHRP-2 decreases vascular oxidative stress in ApoE-deficient mice without reducing atherosclerosis development.
