Glutamine is a waste of money.
Sure, a superior protein with a high BCAA count (not whey concentrate crap), creatine, NO2 -- they all help and you can get it all in BIG BLAST.
But directly in terms of testosterone elevation, liver detox, anti -e, libido, and blood volume -- all lost after cessation on steroids, you've got to go with UNLEASHED/"POST-CYCLE"/ VIGOR. That's what these products were specifically and uniquely designed to do and they do it very well.
