1. He shouldnt need to take more than that.
2. Taking it about 45mins before training is excellent. Gives a really good energy
boost for the workout.
3. Two weeks off and on is a good idea. That way your body won't get used to the
effects, and gives the ol heart a break for a bit.
4. He should definatly stack it with caffene and aspirin.
This is what works best for me IMO. on the two weeks off, I use clen. I've already lost close to 25 lbs in about a month and a half. I'm preparing for my cycle in april. This should help your buddy out a little.
Cheers!
