I have used their creatine products and true mass. For me they worked pretty good. NO explode worked like crazy, helped me get over some hurdles. True mass helped me out during a loading phase last year while working on deadlifts and squats. Although i figured, i could use ON’s casein, whey and a banana for the same or better results. Im not a big lifter.. i just have some goals in my head that i wanted to reach after getting surgery on my back. Supplements helped quite a bit. I had quite a stack going last year but now its mostly just animal paks joint packs, Multi vitamins and whey protein since i havent really been working out for a while now … just a couple of days a week of weights and the rest is walking and a bit of cardio.
