thinking about taking this any tips?

I wanna start nad and my mom on nad but she’s on high blood pressure medication. Would this be good idea and if so what does to start. Any info would be great. Both on Reta

I do 2 mg daily. Is that to much? Should I take something to help it? Is there a washout period? Just anything you recommend let me know please.

What is a good starting dose and then make my way up to what does. I wanna start it.

what is a good 5 amino dose. Ive seen 1 mg daily but that would be expensive because they come in 5mg vials lol im already on 2mg weekly lost about 25 pounds.
