I got these from Muta a few months back before the Anabolic Nation line officially dropped on his website and he hooked me up really nicely. He sent me more than what I had paid for, and it was my first order. That in itself is really fucking cool. I labeled the amps myself; there are 3 x Test propionate 250/ml and 1 x Test 500 Enanthate. The gear is great. I have limited experience with gear in general, but I can tell you that these oils do help build serious muscle and strength. That is my personal experience with Muta's oils. They were smooth as well, minimal PIP. I'll be putting in another order again next week, can't wait to see the new labels.
