i think 3 weeks is enough time. i'm not sure how comfortable i'd be using ugl as my primary source for trt. there's always a chance of a source making a bad batch, or getting shut down or what have you. at least with prescription, you have a guaranteed source that's never bunk or underdosed. OP what are your thoughts on this? have you considered these things?
i only ask because the thought crossed my mind to do the same, but i am worried because of the reasons i stated.
