Looking to brew a blend of test e tren e and mast e at a total concentration of 457 mg/ml. The blend will consist of 57mg test e, 200mg tren e and 200mg mast e per 1 milliliter. I'd be pinning 1ml EOD for a weekly total of 200mg test 700mg tren and 700mg mast on a 12 week run. My recipie will be 1% ba and somewhere between 9% and 19% bb...open to suggestions here??? I brew in Miglyol 840 and tolerate it very well. I've brewed a similar test tren mast blend before but all short esters at a total concentration of 215 mg/ml and pinned it all with very little pip and a high degree of success. So I'm basically wondering if anyone has thoughts on how much bb I should start with and if you think this is a reasonable concentration for a long ester blend or just too high?
