good question. my thoughts on this are pretty straightforward
#1 the objective of trt is to put your numbers where they SHOULD be, not to put them too high. 1000 test levels year round for years will knock years off your life i promise you. you risk estrogen, androgen, dht, and other sides. you also risk organ strain. so 1000ng/dl levels is NOT trt. doctors agree that the number should be 300-1000. so 1000 would be a 22 year old and 300 would be a 70 year old. there is a reason nature drops T levels as you age. so 600-650 area that is more where it should be for a normal middle aged guy, not 1000
2. anything you add to trt from there disqualifies it from being really trt. so if you add var then you are no longer on trt, you are blasting. so by all means you have my blessings to blast, but with a blast you need to make sure you spend more time at your correct trt level than having more hormones then you should
of course the above is under the assumption you want to do this long term and as healthy as possible. a lot of guys have argued with me on this and said you should do trt 'based on feel' so they run more than they need. those are the guys who become strains on the healthcare system in their 40's and 50's
