I don't know why you guys are making this personal, because you're both right on certain points. TA you are correct, there is no such thing as "cruising" or "bridging". You are either on or off like a light switch. Ross, there is no such thing as being a little bit pregnant either and that's what you are implying by saying either of those two words. It all boils down to your goals.
Ross is right in the fact that once your gains have exceeded what your body can achieve naturally, I don't give a rat's ass about PCT, training and diet, you can NOT maintain that level naturally, you need to stay on to maintain what you have or to continue to grow period.
That level of muscularity is different for all of us and for you guys to bag on each other's accomplishments is wrong. You both look good. TA, if you can go off and maintain that's great keep up the good work, but don't put Ross down if he needs to stay on to maintain his level. It's all about individual differences.
Yes, if you stay on for too long then you risk being shut down permanently. If you are willing to accept that consequence again, that is a personal decision that only you can determine, then you will be on HRT/TRT the rest of your life. That's a big decision and not one to be taken lightly.
I'm a lifer. I am 51 y/o and have been using since the early 1980's. I am an IFBB pro and have had my pro card for nearly 20 yrs. I occasionally compete in shows so to maintain my level (5' 9", 240-275 lbs and between 6-10% B/F) I stay on yr round. Fortunately I have had no negative sides and I am under a Dr's care to stay healthy. It can be done you just have to be responsible and being blessed with good genes doesn't hurt either.
Peace!
