Everyone is different, but I agree. Superdrol is a game changer. I've used it 2-3 times. I've used 20mg's per day for four weeks as well as 30mg's per day for 4 weeks. I never had any obvious side effects and my bloodwork always returned to normal after pct. Nothing, and I mean nothing has physique changing effects like superdrol does. It is a great kick start or finish to a cycle. I used M-sten once at I believe 20mg's per day for four weeks and it felt pretty similar to superdrol. Strength was probably better on superdrol but physique effect was about identical. If I ever found myself looking to compete again, I'd run it my last 4 weeks of prep, right into the show.
