good test levels from it....of course in the beginning the pain was a little much, but it can be delt with by mixing....overall moderatly good stuff.....
ttokkyo sust is the only AS that has ever caused injection pain for me. I had no other sides and Gains were decent but I have since sworn off sust all together and stick w/cyp or enanth. I have also used Organon sust with no pain and good gains but still feel you don't get enough bang for your buck w/sust.
