I gained 9lbs of good muscle mass (mostly in my upper back and deltoids) and saw some serious vasculature increases. I didn't get bulgy veins (my arms already are) but I got some freaky looking blue-veins showing up right in my biceps and I still have them. One of them splits off into three branches and kinda looks like a tree.
7+ years lifting without designer supplements and I never saw vascularization quite like this. Some say it's gross but I like it! Of course it's only prominant after lifting, but it's fun to flex and see the blue tubes going all over the place. I've kept my gains a month and a half later, but I was using Forged Lean Mass (Superdrol, Epistane version), but I bet any brand Superdrol/Epistane combo would produce equivalent results. Some of my bulkiness has shrunk down (I got some water retention that actually made my shoulders look more built than they look right now, but not much. If you keep you regimen up like it is on cycle, then you should keep your gains.
