So are they telling you that you will be on it for the rest of your life? Did you go to your regular doctor or did you go to one of these TRT clinics?
Yes it is a lifetime thing you are replacing your body's natural production. It isn't something to just hop on and off like a steroid cycle. It's gotten a bad rap because of these for-profit clinics that are writing scripts to guys with 500-600 levels that don't actually need it they just need to reevaluate their lifestyles and it would bring their levels up to "optimal". For those that are truly low it can be a game changer.
The other downfall to a lot of these clinics are they just shove out cookie cutter programs like 200mg/wk and then all of a sudden joe who wasn't even really low gets a whole mess of side effects from bloating, raised bp, etc. That and they will prescribe an AI and guys will tank their Estrogen and the whole host of stuff having to deal with that.The good ones that tknow what they are doing now are having guys start at much lower doses sometimes 80-100 mg/week injecting multiple times a week to mimic a more natural production to help avoid the roller coster rides.
For those that don't break below 250 you won't get your doctor to prescribe it to you. Most likely even if you do fall below that they will send you off to a specialist who will want to do some protocol of 200mg shot every 2 weeks which is just as dumb as the clinics because the peaks and valleys. Honestly there are some really good clinics that specialize in this but it is hard to find them.
Edit: sorry for the long winded reply. Just something that I have been "studying" for the last 5 years since it became aware to me.
