In a way they do but you can;t make medical claims with any supplement. Instead, we need to rely on the bodybuilders knowledge and reasoning. POST CYCLE balances estro, regenerates liver cells and helps with erectile function -- all things that help in recovery. UNLEASHED increases FREE testosterone which helps maintain muscle, keep estro in check and allow the body to have adaquate T while it recovers. So it doesn't CURE anything (nothing does) but it assures you don;t lose your gains or feel a "dip" while you recover. And following with BRIDGE brings back the pump you get from steroids. It's a perfect combination.
REALITY CHECK: People want to think that as long as they take this drug or that drug everything will be fine. PCT is not that simple. Most guys wind up with depressed HPTA's for life because they thought all they needed was "tried and true " drugs. Don't be a fool. Do it right. Do it smart.
