I think 25mg e3d would probably be too much, aromasin is very strong. I can't think of a way to split the caps in half that would necessarily be easy or fast. Personally I would recommend waiting longer than week 2 to start the aro though. I'm running dbol and test e @ 500/wk right now and I'm taking 6.25mg eod, but I'm not even sure if I should be taking that or not, it's just a precautionary measure. Listen to your body, and use the aro at a lower dosage if you start to get any big estro sides.

Split the caps and on to a small somewhat enclosed surface. I use one of my daughter's kitchen plates from her play set. That plate is obviously not used for play anymore. Once you open the cap, stir the powder around well. Then you split the powder in halves. Ill put one half in a drink or whatever is available to take it. I will put the remaining powder back in the cap.
