Hey. I just received my Unleashed (Protein Factory) and I've got some(Twin Lab) that I'm going to "stack" with it. (heh. stack). Anyway.. What do you think of that? I also have some 6-OXO that I've been taking - and figured I may even keep that in the mix.. What's the best one could possibly expect? At 33, could this combination actually raise my testosterone levels?
