sust is gentler, you feel it much sooner, but enanthe being the rougher one is always good, rarely found conterfeit I think but then again I always bought it from pharmacys, sust is prefferred though, just take alittle more then U would of the enanthe. I tried omnadren though, and would prefer real testoviron over that, though it worked good.
But would like to try the french stuff heptylate, gonna find it someday........
