DUDE. NO. Im no expert but ttokkyo is the third type test ive used and I did not like it at all. PAIN, shit try walkin around with a basketball in your ass even with deca mixed with. Gains i wasnt happy with at all. I had a killer cycle and if it werent for tokkyo dbols (which did work well) i wouldnt have gained much from the test. I had brovel deca. Anyways, I have tried cytahoh sustanon, test ethanate and testanon 250. Ethanate all the way bro. I think the stable levels everyone raves about on here with ethanate really has truth. I would go with ethanate. Granted i dont know near as half as what most others on this board do, but i train, eat sleep and cycle right and i know what i feel. Just my two cents tryin to help you out. And i aint bashin tokkyo just tryin to be honest. Good luck. Maybe you will do better with testanon then me. Anyways good luck again. Peace
