no.....androgel tries to make your levels in the normal to high normal range which is like when you were in high school.
so it does not have enough testosterone per dose to do anything for muscle building purposes.
that said, the test base transdermal has a higher dosage and would be possible to maintain super physiological levels with it. you could do this with androgel you just might need the way more of the dosage then you are supposed to take.
i don't know about the shbg thing or aromatization aspects....but basically androgel is like taking 100 or lower mg of test per week (trt dose) and test base could get to dosages of about 500 if you wanted to
