In my honest opinion, PRIME was made for powerlifters. The benefits from PRIME fit perfectly with our demographic. My personal favorite benefit of PRIME is the 'strength' gains that you will see. I quote strength because it is more than that. I call it sustained eccentrics. Most powerlifters are familiar with the term eccentrics, it is the extension portion of the move, increasing the joint angle.
You will see sustained eccentrics as an increased drive through this portion of the lift. Within the second week of my personal PRIME use, i was tripling my PR on squat. The sustained eccentrics allowed me to drive through the sticking point of the lift. What else can a PL'er ask for?!?
PRIME is excellent for powerlifters due to the strength gains as well as recovery aspect of the product. As i am sure you know, recovery is key in the powerlifting game.
Personally, i have never used a product that has effected my training the way that PRIME has. My focus, drive, aggression, etc are all through the roof. I know this sounds manufactured but keep in mind, i was a user of USPlabs products long before i became a rep.
Check out Kabuki's logs, he is a top natural PL'er with a very serious total:
My Next Meet Training – Prime & Recreate clean bulk!
Kabuki's "VIDEO" Log - a little crazy fun for everyone
He has been using PRIME for quite some time and was one of our beta testers.
Also consider stacking Anabolic-Pump with PRIME/PowerFULL... this is an excellent idea. Anabolic-Pump will allow you to consume the necessary carbohydrates, reaping the benefits of a high carb diet, without gaining unwanted bodyfat.
The Anabolic-Pump/ReCreate (Six-Pack Stack) stack helped me in more ways than i can explain. It is actually the reason that i work for this company now. The stack allowed me to drop from 276lbs to 242lbs, all while retaining my bench and deadlift and actually gaining significant numbers on my squat. I told EVERYONE about it. Through my personal researching of these products, i gained a significant amount of knowledge pertaining to USPlabs products. It was soon after this that i was asked to come aboard the USPlabs team.
If you have any questions regarding these products in relation to powerlifting (or any sport, for that matter) please contact me.
Best of luck buddy!
