I wouldn't use milk thistle, get NAC. Cheaper, run 400-600mg twice a day. For pct, I would use a serm, and run a test booster/libido booster like reversitol v.2 or intimidate along the side. Don't forget about the most important aspect of running a cycle, your health. Protect your heart, it is one of your most vital organs. Designer steroids significantly increase cardiac values like cholesterol; get some blood work done and you will see. I would run something if not both on and during pct, def during pct like Heart Help to keep cholesterol down and restore it back to normal values faster.
