WOW is all I can say!! I took my last shot of prop a week ago, and started using IGF (via MR) nearly two weeks ago for PCT. I have lost water weight which I can see, but lost only 2 pounds so far, which means I must be keeping my muscle mass. What surprised me was, I actually lifted MORE this week then I did last week on big exercises (bench/deads). Worth the extra money? I DEFINITELY THINK SO. Can't wait to see how these last two weeks pan out, hopefully I don't lose any more weight!!
