In 1989, as a 23 year old, I weighed 175, lean, ripped, etc...
27 years later (2016) (as a natty) I weighed 200 lbs. So almost a lb. a year (lean tissue, no fat gain) 25 lbs. in 27 years.
(Anyone can gain fat, I did not go that route).
Went on (real) TRT at that point (age 50), 7 years ago, and still weigh 200 lbs. Real TRT is .5 cc a week, 100 milligrams.
Not the 500 mg's other speak of as "normal TRT" these days...
When I was 40, I got tested and was at 730 test level naturally.
A decade later at age 50 and on statins, I was at 253 test level.
.5 cc brings me back up to my normal natty range for that age. (At 717, recent test)...
