NAD+ vs SS31

[ghreid]

Just started both of these peptides abouit 2 weeks ago. NAD+ 50mg 3x/week and SS 31 daily in prep for MOTS -C. I noted while pinning the peptide, that I have started to develop subcutaneous non-painful nodules at injection site. Not sure if due to NAD+ or SS 31. Anyone had the same problems? not sure which peptide is causing this. Thanks
