The concentration is the problem. I've done several experiments with this compound and the best I got with regular oil was 200mg/ml at 3/20. EO seems to help with compound even though its a longer ester, not sure why. 50/50 EO and oil will get you 250 but any higher and you have to use straight EO and 4 to 5% BA.
When you start using it start at a low dose, 400mg per week then increase from there. The cypionate produces flu like symptoms in some at 600mg & higher doses and it doesn't take anywhere near as much of it to produce the same results as EQ.
