Sust is going to be painful but I heard if you mix Tren with sust then it help out a lot. I was talking with a buddy and he told me about injecting b-12 with the sust will also help the pain. I am trying this next week because right now it feels like a damn golf ball is in my leg. You will see good gains on sust just becarful with the stanozolol. Take milk thistle and don't forget clomid and HCT for after the cycle of sust.
