The "Hello Pharmacist" brand contains 5mg per pump. The directions say "one or two pumps per day".
My advice is to always start low, to allow your body to adjust, and to see if you have any adverse reactions.
So, one pump would be the starting dose and if you get results with one pump, maybe you don't need two?
PM me sometime. Would love to know how long it takes for you to start seeing or feeling results.
