Ok, let me try. So you have Tren E 200mg/ml, Mast E 200mg/ml, and a Test blend of 500mg/ml (???)
So to inject twice per week puts you at a gram of Test, 400 and 400 of the others. 3 times a week is 1.5g, so NO
First let me address the 500mg/ml Test. It's probably not. Hard enough to get 300 to hold, 400 is pushing it, 500 is just lab BS. It's not physically possible. Yeah yeah someone's gonna come try and say if you do this or that it will hold. It won't. So let's say you have Test 400 tops.
I would go .5ml twice per week of the Test, 1ml twice per week of the others. Possibly 1.5ml twice per week of the Mast.
