well I don't know your cycle experience, but the only difference between the two are the esters. Ones a long acting ester
tren E and one's a short acting ester
tren a. It your going to be using other short acting esters in your cycle then go with
tren a which would go good with
test prop. If your going to be using long acting esters then go with
tren e which would go good with
test e. It all depends if you want to stick your self every day every other day or once or twice a week. Trenbolone is trenbolone it all depends how you want to use it. As far as mls go, that depends on your cycle experience.
