Was last year the first time you ever had post-cycle bloodwork?
Whenever I talk to people that have experienced similar situations, they feel like it was a slow process that finally came around full-circle as opposed to something that snuck up after 1 cycle.
At this point, if you have exhausted your natural test boosting remedies with no success, it might be time for HRT.
Don't be depressed about that, because when you do finally get back to a normal level, you'll be happy you went that route.
Best of luck bro.
