Ok guys my source recently started offering test base and tren base which i know has no esther....right now i am on break but about to start back test prop tren ace cycle. I am just wondering what is the difference between test prop and the base and tren ace and the base? The ones with an esther have short half lives and i usually run 1/2 ml a day of tren and 1ml eod of the prop.......any advice?
