Woe brother slow down on the clen. Not that the dosage and timing isn't a technique, but where were you planning on adding that in?
I am assuming that you have your diet in check... Diet is going to get you to cut as you should know. The mast is great if you are already really low BF. I have never been down in single digit bf.... so Mast wasn't that great for me in that regards. The cycle above before you talked about the clen seems to be a fairly mild and safe one.
was just about to ask his bf for this reason, although, i do know of guys using mast for strength while on low cals.
i wouldnt bother with clen, its overrated and not worth the poss health consequences
