I've been on this for two weeks and WOW!
I've added just over an inch to both arms with only two days of bi's and tri's during the cycle. I've noticed some water retention and I'm sure a bit of the size is from that, but still I'm very impressed. My girlfriend didn't even know I'm doing a cycle and she commented on how much mass I've seemed to build in both my arms and traps. I was going to follow a month of this with a month of M-Drol, but I'm tempted to just do 60 days on this now.
Anyone else with experience? A buddy of mine swears I should stack Tren Xtreme if I run a second month.
