I'm on Pro Max Phase II at the moment.
I've been taking it for about 7 weeks.
What I've noticed: Strength increase, better recovery, small libido increase, better general feeling and mood.
I've gained some mass with minimal fat but I can't attribute that solely to the Pro Max as my diet & training have more to do with that I believe.
In the 7 weeks I've gained 5 lbs. (but I'm sure some was water after going from a cut to bulk)
I will post a review when I'm done.
I think both BF and BF PM will offer similar benefits. Increased strength & recovery, assist with lean mass gain, increased libido, and overall recomp (dependent on diet).
