I brewed both Test E and Deca separately. Both in MCT oil, using 1%BA and 5%BB. Both at 300mg/ml with 0.4% overdose. All filtered in their own vials. If I take a new sterile sealed vial Put 5ml of Test E 300 and 5ml of Deca 300... Vent and heat vial to around 160F, remove vent and shake vial for a couple of minutes... Theoretically 1ml would have 150mg Test E and 150mg Deca. And a 2ml injection would be 300mg Test E and 300mg Deca. The ratio is basically 1:1 I already did a test with 1ml of each, and it seems to have worked. However, would it be accurate if I drew, lets say 1ml, I would have 150mg of each? It seems all blends would come down to the purity of each compound. So they may be off a little in some instances. I was using 1:1 as an example for explanation. Left to right: Deca 300, Blend, Test E 300 I told my daughter to math up a 2:1 ratio. This is what she gave me. I added some other math as well.
