I got up to 193 @ 5'11'' and 8-10% bf naturally. That was my absolute max.
Now I am 230 lbs, between 5-6% bf, 5'11.5'. Although I was measured at my doctors (I had to go get an immunization record today for my phd program) earlier in the week at just over 6 feet (6'.25''), I think they messed up. I will do some more research into this later in the week regarding my height.
my first cycle was test only @ 750 mg a week, i think it was cyp. or actually my first, first cycle might have been british dragon tren E with a kickstart of haladrol LOL! I don't remember.
Either way, I was a child when it started. I remember gaining 20 lbs, then losing all 20 of it after pct after my first cycle. And I would repeat this a few times a year (gaining 20, losing 18... gaining 20, losing 17, etc') until I said fuck it, I am never going off. And like magic, I am now 230 lbs @ 6% bf.
I don't even lose any weight when I bridge @ 250 mg of sust per week for 2 months. That is a testament to how fucking magical hormones are. Even 250 mg of testosterone- a baby dose- is enough to support a HUGE amount of muscle.
