Ipamorelin is a 3rd generation GHRP (growth hormone releasing peptide) which is similar to GHRP 2, GHRP 6 and Hexarelin. Ipamorelin acts synergistically when applied with a Releasing Hormone pulse or when it is administered along with a GHRH or an analog such as Sermorelin or Modified GRF 1-29 (growth releasing factor, aminos 1-29).
