I'm over here using 27 and 29 like some kind of pleb, since they don't cost me anythingtrey915 said:
My NAD+ gives me that burning sensation too. A handful of adjustments have made a difference.
1) As time goes on, my body has adapted, so the sting has eased up somewhat
2) I bring it up to room temperature before use
3) For 1000mg, I mix in 5ml
4) Pinning into my thighs hurts far less than the abdomen, I noticed
5) I switched to a bigger needle compared to my other peps. Other peps get the 32g, but this one gets a 31g 4m.
Hope this helps.
