First of all, during the cycle you will need to use an AI. The arimidex you mentioned could work, but Aromasin would be a much better choice. It is a suicide AI, so there will be no estrogen rebounds. Also, unlike arimidex aromasin will improve cholesterol levels. Then you will need N2Guard, because in spite of being an injectable, Tren is still liver toxic. There is no need to use HCGEnerate during the cycle, and it is best used during PCT. Then, you should have on hand some cabergoline in case prolactin side effects take place from trenbolone. Cardarine GW is an awesome addition, as it combats more of trenbolone's side effects.
