If your looking for a clean and powerful test booster? this is the one for you! im on week 3 and im crazy about this product. I have set PR's in almost all of my lifts lately!! i have never touched 135lbs on the barbell skull crushers, and i got 6 reps the other day! Clean! im at 193lbs and when i started i was 187lbs! i look leaner! and massive! i been killing traps/back once i started this and i can easily see the results in the mirror! amazing product! definately consider it if your looking for a REAL test booster!
