Christ...
At my peak, circa late 2013, I think I could manage a strict set of 10 with 55s or *maybe* 60s on DB curls.
But for multiple sets, let alone for 15 reps per set? LOL. After that initial set of tenish to positive failure, I would set them down, take ten-fifteen breaths, have another go at it and maybe get 3 or 4 more to failure, followed by one more 10-15 deep breaths and a final attempt to rep to failure, probably only getting two or so, followed with a cheat rep or something.
You know, DC style.
After that, my biceps were so pumped that it actually hurt; it felt like kmy skin in the area was about to rip.
I followed that with a hammer curl variation, and just one set of those to failure and cheat reps and partials...mein Gott. I couldn't even touch my forehead.
Granted, I was taking 250 mg of test E per week at the time, but that's a small dose, and my workload was a joke compared to yours!
It served me well. but I loved training

I did as much as my body could handle and recover from consistently, but sweet Heavenly Father, if I had the time, money and ability to progress by lifting many hours every day, that'd be this side of Paradise for me in this mortal coil
