Yep , you can increase that if you can.
When I had my stomach surgery in 2019 I started HGH a complete weeks out at 4iu a day.
First surgery went bad and ended up needing a big emergency surgery the next day , initial prognosis was that I'd be in ICU for 10-12 days and regular room another 10-12 days. I end up in IUC for 3 days and regular room for 6 and the Drs siad they didn't understand how everything was healing so fast for a 43 year old. Granted I was healthy going into it I'm convinced that the HGH helps the recovery.
