Dude, this is not really the right board for this question (it might be better suited for the supplements board), but I will try to help.
Everyone has different regimens. Depending on what he was taking he may not even need anything. Most of that stuff doesn't work. However, the question is common and if you just search for a bit on the board you will find all kinds of regimens.
Another option is the new 6-OXO. On different supplement boards, people are claiming that to work. Don't know for sure. Good luck.
