When I had it with a doc he had me on test cyp 250 mg/ml .4 ml 2 x week. I did good on that with my test levels. Moved and have never found a doc since that would prescribe me self injections. I am out of town too often to hit a docs office once a week for a stick. Currently trying out the Testopel. Will get blood levels in February and know results. But I am not too fond of it. My ass was sore for two weeks and I don't feel as good as I did on the test cyp.
