NAD+ ⇒ NAD+ IV vs NAD+ Subcutaneous Vs Muscular Injection

Which is better and why?

...any opinion? thoughts?...

[Drdavid]

From experience I would say that IM is better than SubQ.  IM is simple effective with very little pain and delivers consistent results.  When we were doing SubQ injections the results were hit and miss.  This information is strictly from my observations within the clinics not research.  I would like to know if anyone has had different results.
