About Mod-GRF(1-29)

Modified GHRH(1-29) analogue with four amino acid substitutions that dramatically extend half-life from 2 minutes to approximately 30 minutes. When combined with Ipamorelin, produces synergistic GH pulses that mimic natural pulsatile GH release patterns. Considered the cleanest GHRH analogue with minimal side effects.
