Most peptides aren't really anabolic. Insulin might count as one, but beyond that the real drivers are still food and sleep, especially once you're this far along in training. You could try some of the recovery and anti-inflammatory options like BPC-157, TB-4, TB-500, KPV or GHK-Cu to help you bounce back faster between sessions.
Been using Tirzepatide around five months now. Dropped 27 pounds and still want to lose another 10, but I've definitely lost muscle in the process. I've been lifting heavy five days a week for over thirty years and my top numbers are lower than before starting the medication. At this age I want to cycle some peptides to get the muscle back. Any suggestions?
