I used this product during my 12 week bulk and have finished several tubs over the course of the last year. I was dosing this as 5 grams PreWO, 5 grams IntraWO, and 5 grams PostWO. On off days I would take 5 grams with my morning shake and 5 with my evening shake. The othere supps I was running during my bulk were: Kre-Alkalyn 1500 Powder, Gluta-Lyn 1500 Powder, Prota-Lyn, Animal Pak, MRM CLA 1250, Digestive Enzymes Plus, Beta-Alanine 2000, 12 Hr Protein, Flaxseed Oil 1000, ZMA, Sleep 'N' Tight, and Nitrox II. I immediately noticed a difference in muscle fullness and soreness both during and after lifting. The most noticeable difference was the muscular endurance I had in the gym, where normally I would be breathing heavy in between my sets and getting weaker, I seemed liked I could go on for days. I had tried Xtend previously intraWO before this and I felt no difference in recovery. I believe that this along with gluta-lyn, kre-alkalyn, and beta-alanine make an amazing PreWO, IntraWO, and PostWO. I didn't need to use any stims whatsoever during my bulk thanks to the natural energy I received from my supplements. I would highly reccomend this product to someone as it is both cheap (buy 2 get 1 free on BB.com) and extremely effective.
