The story

For years practitioners drew Mod GRF 1-29 and a GHRP into the same syringe, because the endocrine work from the 1980s and 1990s showed GHRH and GHRPs multiply each other. Bowers's lab at Tulane and Popovic's group in Belgrade showed the combined pulse far exceeds either one. Ipamorelin from Novo Nordisk in Denmark became the favourite partner because it adds no cortisol or hunger. Pre-mixing the two in one vial simply made the standard pairing easier to use.
