Will you have to stay on the shots forever or are you doing things in conjunction to stay at good levels (if so, what? Sounds like your lifestyle was already healthy)
With regular TRT shots, I've heard that there is a possibility that the baseline will lower due to changes in the HPG axis, leading to decreased production of LH and FSH, which leads to less testosterone being signaled to be naturally produced.
Taking extregenious testosterone disables your natural production. If you want to fire it back up you'll need to take hcg or clomid as post cycle therapy.
When on TRT, the naturally produced stuff is for all intents and purposes useless because you will be shooting up plenty that any extra will probably aromatise into estrogen anyway.
