The gear goes by blood work that I've dialed in over the years and it evolves. i go completely off twice a year, once for 8-10 weeks and once for 4 weeks roughly. When I'm off I support with hCG and a SERM, one or both. I TRT another 6-8 weeks twice a year usually just after the 4 or 8 weeks break. TRT is Test P 50 mg EOD or MWF. Then I ramp up slowly and peak at around 750-1000 mg total gear. I have two favorite cycles. 1. Test/Primo/EQ, 2. Test/Mast/T-bol. I might sub-in things here and there.
Training has changed a lot since the back and knees have degenerated. Bone on bone in one knee on the lateral side, the other one is OK but has ACL replaced. Back is degenerated L3-S1 but no surgery. I never go over 225 squatting and usually much lower and just going for reps. To much and I am in pain for a month. I do a range of stuff for legs, leg press, extensions, leg curl variations, reverse hyper, step mill, belted squats. For back I have to be careful I can do rack pulls part of the year. Other stuff is mostly OK but very controlled and with pauses and slow cadence. I can't go as heavy as I use to by far. Shoulders and chest I can still go fairly heavy but usually go more with very controlled and with pauses and slow cadence.
Main thing is i have to listen to my body and adjust or i will pay and be forced to work around injuries and inflammation. so in the end it's better to strategize rather than go balls out and end up with more surgeries and pain. There are such things as good pain and bad pain.
I track bloods pretty closely and strategically. Things that most of us see going out of range do go out but so far the mild strategy I use keeps things fairly close to in range. I'm 61. I'm not sure how much longer I will keep going like this.
Unlike most, I like the off and TRT periods. the steroid pump goes away, the cardio improves, and athletic activities are more pleasant. I like to hit the speed bag and heavy bag, shoot some hoops, bike in the hills, do 1/2 sprints and such. I'm to old and broken down to compete in anything but I still enjoy those activities and the fitness that comes with them.
