Description

Mod GRF 1-29 is the GHRH(1–29) sequence with four amino acid substitutions (D-Ala2, Gln8, Ala15, Leu27). These changes reduce enzymatic breakdown and oxidation relative to sermorelin while keeping a short duration of action. Researchers use it to study GHRH receptor activation and pulsatile secretion models, often alongside ghrelin receptor agonists.
