Doesn't losing weight already increases your Testostrone?.. people seriously shouldn't get on TRT unless they need it medically, once you start it, it's for life and also you will be infertile.. (source I am on HCG, an alternative to TRT due to its side effects).
That's correct - you need to be seen by a doctor before embarking on TRT. For me, I have no intent of having any more kids. Infertile can be reversed.
