I would break down the dosages to 5mg a pop spaced out evenly during the day to maintain stable blood levels.
When I take this stuff, I plan to take it like I would DBOL which would be about every 4 hours.
Take it as soon as you wake up, and 2 more dosages about 4-5 hours apart, and again before bedtime. That = 20mg
You could take 10mg at once, I think there are a few formulas that have it in 10mg dosages? I have read a few reviews where a few people took larger amounts with the same gains as the regular smaller dosages. So it may be pointless to take a high does at once and or take over 20-30 mg a day.
My biggest concern would be to maintain stable blood levels.
I would take it about an hour before I work out with about 16oz of water.
How old are you or the person that wants to take it?
