Most endos won't help you come off other then telling you to stop cold turkey and then waiting. Standard protocol is 6 months blood work and a year blood work to assess testosterone recovery before writing any scripts. Unless you're lucky and find a really good Endo.
I'd just blast HCG, hmg and nolvadex for a few months if that doesn't do it you're probably screwed. Patience is important, if you've been on for multiple years it might take 1-2 years for a half ass or full recovery if you're lucky.
I went 2 years off completely and used HCG, hmg + nolva in cycled intervals and still had a testosterone of 0.3 ng/dl, non existent. Some get lucky some don't! Goodluck mate
Tell me about your blast curious what it consisted of and how it failed, was lifestyle not dialed in?
