CEL have a liver support product called cycle assist, which I'll be using for my next cycle:
Whilst I have not used it myself, it has an excellent profile of ingredients, very closely resembling Cycle Support by Anabolic Innovations:
I used Anabolic Xtreme's Perfect Cycle for my last M-drol run (4 weeks, 20/30/40/40), although personally I feel that the two I've posted above are better products.
What's your cycle going to be like? Have you got a PCT protocol in mind? (You need liver support for PCT as well).
