I’m so excited to start my second round of 5-amino and AOD. This time I also ordered NAD+ and GHk-cu. (I am brand new to these two) I assume these are okay to stack together? Has anyone combined NAD+ and 5-amino into one syringe? Especially to soften the sting. Anyone noticed any difference between taking GHk-cu in AM vs PM? Love to hear your experiences, results, tricks and tips. Thank you ladies!
