Reta and CJC/Ipa. Upcoming surgery and Klow

Currently at the 4mg Reta dose. Just started cjc/ipa so the dose is low.

I’m expecting to have a major ankle surgery in about a 6 weeks and from reading it looks like Klow is excellent for surgery recovery.

Should I begin dosing Klow now? Or would it be best to wait till after surgery to begin?
