I've been running the following since March 18th and have never had a site reaction other than to the GHKcu. Now, 3 months later, I get ISR even with Reta. The reaction is an itchy welt similar to that of GHKcu but the Reta ISR occurs about 48hrs after pinning. I do not pin Reta and GHKCU in the same place as one another, and I rotate injections spots. I've tried reconstituting new vials of each, new BAC water, taking an antihistamine, and took a full week of all peps while I traveled. Has anyone had a similar experience?

Reta: split dose since 3/18 - Pinned in belly
NAD+: 3x a week since since 3/31
GHKcu: daily pinned in upper glute/love handles since 4/20

Are you wiping the tops with alcohol and yourself with alcohol prior to injecting? And do you filter?
