For a typical 4-week vial with weekly injections, four brief exposures totaling about 40 to 60 minutes is completely normal and has minimal impact on potency

If PCAC recommends inclusion and the FDA agrees, the supply side becomes the next bottleneck

At the molecular level, 5-amino-1MQ functions as a competitive inhibitor of NNMT, demonstrating remarkable potency with an IC of 1.2 0.1 M under standard assay conditions (50 M SAM, 100 M nicotinic acid). This represents a dramatic 10-fold improvement over the parent compound 1-methylquinolinium, achieved through strategic amino group substitution that enhances binding affinity to the NNMT active site. The compound's mechanism centers on preventing the methylation of nicotinamide to 1-methylnicotinamide (1-MNA), thereby preserving nicotinamide for recycling back to NAD+ through the salvage pathway. This intervention effectively blocks what researchers have termed the "NNMT metabolic drain" a process that simultaneously depletes NAD+ precursors and consumes cellular methylation capacity
