Manila has the densest concentration of healthcare workers and health-science students in the metro, and it shows in the mail. The questions I get from this district are about mechanism and administration rather than about whether the compound is real: how the sirtuin and PARP pathways relate, whether the CD38 problem changes maintenance dosing, why subcutaneous stings the way it does. Nobody here needs the basics explained.
What almost nobody in this district factors in is that their own schedule is the primary risk to the delivery. A twelve-hour shift, a night rotation, an exam week: any of them turns an address into an empty room during the exact window a courier is trying to reach it. In a BGC tower that costs you nothing because the concierge holds the box. In an Ermita walk-up it costs you the delivery, and on NAD+ a failed first attempt is not a neutral event, it is a box that spent a day travelling for nothing.
For the record on the sting question, since it comes up here more than anywhere: subcutaneous NAD+ stings more than the short peptides most people start with, and the reason is molecule size rather than formulation. Diluting properly and injecting slowly is the fix, which means buying more bacteriostatic water than a micro-dosed protocol needs.
