Metabolism Is an Information System: Retatrutide, GHRH vs GHRP, and the Logic of Stacking
Metabolism isn’t a calorie equation. It’s a communication network, and peptides carry most of the messages. That changes how a stack should be built: fix the main metabolic signal first, and only then add growth hormone support. Retatrutide sits at one end of that logic. The GHRH and GHRP classes sit at the other.
