Difference Between GHRP 2 and GHRP 6 | GHRP 2 vs GHRP 6

Summary – GHRP 2 vs GHRP 6

GHRP 2 and GHRP 6 are two growth hormone-releasing peptides. They are used for professional bodybuilding purposes. Apart from that, both hormones have different functions. GHRP 2 is more potent than GHRP 6. The key difference between GHRP 2 and GHRP 6 lies in the amount of growth hormones released. GHRP 2 releases more growth hormone than GHRP 6. Furthermore, GHRP 2 peak occurs within 15 to 60 min once administered. Hence, it has a shorter half-life in comparison with GHRP 6. Significantly, GHRP 6 increases the absorption of nitrogen in the body and facilitates the production of protein.
