Mots-C or SS31 for mitochondrial support, which one are people actually running?

Been running Mots-C alongside GH mostly for blood sugar management and it does seem to help. Started wondering if SS31 would be a better option or if the injection site redness I keep getting is just par for the course with Mots-C. Anyone compared the two directly? I am doing 5mg every 5 days right now.

Ran Mots-C for 12 weeks alongside GH at 2IU. The injection site redness was consistent, every pin. It settled within 24 hours but never fully went away. Did not try SS31 directly so cannot compare but I have heard the site reaction is noticeably less. The blood sugar management benefit from Mots-C was real for me.

Switched from Mots-C to SS31 about 4 months ago. Cleaner injection experience, less site irritation. Hard to say if the actual mitochondrial benefit is different because I changed a few things at the same time. SS31 feels like it has less community data behind it but anecdotally I prefer it.
