Haven't tried NAD myself so can't comment on effects, but I've used the glow peptides on their own. Common under-the-skin amounts start at 20-50 mg and increase toward 50-100 mg, usually a couple times weekly instead of daily. It can hurt if you push it in fast, so the advice is to go slowly.
Anyone here tried NAD? Planning to combine it with the Glow stack. What's your dosing frequency and amount for injections, plus any effects you've noticed?
