Ester mixing doesn't affect the absorption rate of another ester. Esters are chemically bound.
Mixing them together won't slow down a fast acting steroid's action when mixed with a long acting one. It doesn't happen.
Likewise, it won't speed up the action of a long acting one.
A prime example is sustanon, or tri-tren. The fast acting esters still act just as quickly, and the slow ones act just as slowly.
Therefore, mixing diffeent compounds with a fast and a slow ester also will make no difference.
that is what i thought. i know it can be done. i was just saying why would you want to do it. why wait all that time to see results from test e if your going to inject it d or eod anyway. why not just use prop. just my thoughts. if you only want to inject 1-2 tomes per wk use long esters. if you want ed or eod use short. dont mix the 2.
