@Zorachus keep up the good work on this man. I like the different training that you're doing. The chin-ups, the finish is a good ender to the workout. Next time try doing them first and see how many you can do.
I'm not sure that any supplement will work for pain. You might just have to take an aspirin and maybe rest for a couple of days but you can try some joint support.
Trina is a good one. 50 milligrams a day is definitely a good dosage. @jdog32 you can always add in an oral, maybe some Anavar. I think that would help the cycle.
Tren is one of the best but I would stick to eight weeks or less. I would go with Tren Ace. Make sure you go around 200 to 300 mg a week and you'll do fine.
Start low with retatrutide because the first month or two you can get side effects; then you can gradually start increasing it. You'll get great results on that.
Hcgenerate has a lot of options. It's not just a testosterone booster. It's amazing for erections, libido, heart health, cholesterol, and many other things.
