Let's stick with one thing at a time young brother. I thought you were looking at TRT from your doctor, now you're asking about sustanon. Is this to cycle, or to put you back to NORMAL levels?
If you're asking about things in the TRT forum because you want to cycle, that's disingenuous - but not the first time I've seen it. If this is because you're looking at options, that's fine too, but you need to be open about your intentions.
If you have a true medical need, that's one thing, if you're thinking that steroids will transform you into a poon hound - that's another altogether.
