Start with 100mg, and take more until you get the flush
You MUST get the flush
Before orgasm. Get flush, wait til it's over and then have orgasm
Niacin, NOT Niacinamide
You can take a lot of niacin without having harmful effects. It's also known as vitamin b3. It takes huge amounts of vitamins to hurt you. I take 1.25g of niacin to get a flush. That's a lot compared to most, but it is ok. I used to get a flush with 200mg, but I have been using niacin for a while and now I need 1.25g
