All three peptides have relatively short half-lives (Sermorelin ~1112 minutes, Ipamorelin ~23 hours, Tesamorelin ~2638 minutes), meaning GH pulses are acute

Consequently, fitness enthusiasts and bodybuilders prioritising muscle gain may not be satisfied with the results of retatrutide

Similarly, preliminary studies have suggested that Ipamorelin might exhibit effects similar to those seen with Tesamorelin concerning skeletal muscle and bone structures

That gap between expectation and physiology is precisely where protocols fail, not because the biology did nothing but because expectations were never set

Sermorelin has an even shorter half-life than Mod GRF 1-29, approximately 10-20 minutes
