you will be able to build/keep some muscle, but depending on how big you are now it might (won't it sounds like) be what you are looking for. Sorry to hear that for you bud, but you know it happens to all of us. I began the endo route for trt then found out there wasn't one in my area for an hour and a half drive so I'm fumbling through it myself. Still alive so far lol. if I were you, I'd ask for a referral straight away, lift to only maintain muscle as broken down muscle will be harder to grow back with lower test levels. At least you know now. How old are you?
