the esther in enanthate is heavier than that of propionate so their is actually less test in 100mg of enanthate than their is in 100mg of propionate. I am not sure how this transfers to real world experience exactly, but i can tell you that i get better results on 500mg of prop a week than i do on 500mg of enanthate. At least i think i do, lol. It is very hard to gauge. If you are going to do it, i would probably run 100mg of prop eod, and 50-100mg of Winstrol (winny) eod.
