Hey not being a dick there, it's a legit question. I pull in the low to mid 500s right now, and the best I've ever done was 600 @ 240lbs. I used to squat in the 525 to 550 range for sets of 5, but I don't squat much at all anymore, because my lower back is complete mess! I didn't realize how bad it actually was until I retired from the Marine Corps.
As part of my retirement physical I had an MRI done on my lower back. I had 3 full pages of dictation on that alone.....which means my lower back is pretty jacked up. Pars defect, spinal stenosis, a few bulging disks, and blah, blah, blah. I still lift heavy, but don't push the deads like I used to, and I definitely don't push the squats. I've done all the cool and crazy
shit like probably most of the other guys on this forum have done over the years too. Deadlift 405 for 20, squat 405 for 15 and 315 for 25-30, all in an attempt to HHHHUUUUUGGGGGGEEEE!! lol!
I started lifting young like you guys! My best advice to you and anyone else who is really just getting started is to be patient, use good form, add weight to the bar when you can, and be sure and warm-up properly. You're knees and lower back will thank you...TRUST ME!!
I'll be 42 early next year, so the years of lifting heavy have definitely started to catch up with me. Anymore I push goblet squats pretty heavy, and do alot of double KB front squats with the heaviest KBs I can find. It's still a kick ass leg workout, and tends to be a lot less stressful on my lower back.
