Well, you made huge strength gains for having low test levels......If you've got andro gel from your Dr, what the hell, give it a go.....I haven't done much research on the subject, but I was always under the impression that TOTAL test levels are meaningless, and what is important is the amount of test in your body COMPARED to various other hormones (estrogen, epitestosterone, cortisol etc etc).....again, I don't know.....but with the gains you made and the physique you're sporting, I find it hard to believe that your body's own natural test wasn't working as it should have been.
