I have done test d at 220mg/ml at 1.5/10. By adding 10% test to account for the ester I am able to inject 0.5ml and get an effective dose of about 100mg of test c or e. I am fully sure I could have done it with 5% BBCan Test D be brewed with no BB? Or 10% or less. I seem to get headaches shortly after pinning if it's high BB. I believe it's the high BB.
