Im running it (mk677) 5 on 2 off, stacked with cjc w/dac dosed at 750mcg E3D. The stack is awesome. You wanna talk about an awesome, infrequent injection, low cost, gh alternative, what I am doing is it.
Once you find out what you want re: the mk and what it does for you alone you should consider hitting up rui for some cjc w/dac and throw it in along with the mk-677 at 750mcg E3D, its a great stack.
Oh and to counteract the bloat go on a simple low dose daily aspirin therapy regiment. 82mg enteric aspirin, right at the dollar store, taken 1x/day and the water retention will go away. Aspirin effects vasopressin or ADH (anti-dieuretic hormone) and cause you NOT to retain water.
