NNMT inhibition as a metabolic and epigenetic research target
What is not on the FDA's approved list: BPC-157, TB-500, CJC-1295, Ipamorelin, AOD-9604, Thymosin Alpha-1 (in the U.S.), and the other compounds under July review
The ingredients are naturally occurring nutrients, and the side effect profile is minimal
So on the narrow question does it stop working after N weeks, the honest answer is: no published evidence says it does, and the mechanism actually argues against it
Because AOD-9604 does not activate growth hormone receptors and functions through an entirely separate beta-3 adrenergic pathway, it does not trigger cortisol release
