Great replies. Milk thistle, ALA & lots of water. Your liver is very resiliant. It won't show many warning signs. You could wake up one day and the whites of your eyes are discolored. At that point, your in trouble. Prevention is the key. Also, protect your kidneys. Drink tons of water. MAybe even some cranberry juice. D-bol is very hepatoxic. Second only to anadrol. You will definitely grow off 4 weeks, and you will feel awesome. D-bol makes you feel like a million bucks...that is until your lower back starts hurting.
