I've taken Prop and Enan. I grew a lot more off of Enan (could be water), took longer to kick in, and water bloat was pretty bad.
Prop, lean gains, no water bloat, and it took about a week or two to notice strength and an appearnece change. Taking it EOD, I noticed the day I shoot I am bigger, but the next day I start to get smaller. I guess it's due to the half life.
I like taking Prop b/c of the lean gains vs. 10 pounds of water gain on Enan.
