If you check out my post ( New levels at 49 yrd old TRT?) in the TRT/Pharma section you can see me at what I considered my genetic limit. I have pictures in there show pre trt and post.
Methods I used to calculate my limit included. Showing minimal results for maximum effort across all variables with little forward progress over the course of several years.
Did a achieve this? Great question. #Maybe
I’ve been thinking a good bit about this recently. Mainly because I’ve been wondering if some my efforts in the gym would be better spent focused elsewhere. Since we know that it takes much less effort to maintain muscle than it does to build it, perhaps one of the days I spend lifting could be better spent on something else (more cardio – an area where I may still be able to improve, mobility, etc.)
Anyway to answer your question, I think I hit my maximum muscular potential at an acceptable level of leanness at age 45-46. I determined that because I’ve seen no discernable progress from a muscle gain standpoint over a couple of years and my FFMI from my DEXA scans have bounced around 25 for several years in a row.
