<![CDATA[Pens with peptides that "sting"?]]>My rat is going to be researching GHK-CU for the first time and will follow Jeff's dilution video. Can anyone using GHK-CU with a pen share your experience? Does a pen make the sting alot of people talk about worse, better, or no difference? What pen do you recommend specifically for this peptide? I have a Xulin 3 and a V2 currently but will be buying more soon to try. Needles I have on hand are easytouch 31g 8mm syringes and Novofine 4mm and 6mm pen tips.

I have noticed with the GHK-Cu that it never stung going in but about 15 mins to an hour after it was achey, a couple times it ached for a couple days

Same for me, don't experience a sting while going in, but I had 2 nights, at about 2 am, was woke up out of a deep sleep with a sting that came from the depths of hell, lasted until about 5! The devil incarnate, oof. I gave the Annela protcol a try and that has worked wonderfully, no sting since then(hope I'm not jinxing myself).

Inject a couple clicks at a time. Sometimes it burns, sometimes not, but no more than with a syringe. I also love my auto pens. Using one for NAD+ right now and that is a hoot. 😉

My go to pen needle is now 32g x 4mm, though availability of the flat top Gluco-cares is spotty so i buy what I can find.

With that said, NAD+ 100mg burns like a mofo injected anywhere, but only for 10-15 seconds while going in. All in all I'll take the pen and Nanos over the pins any day. I do NOT enjoy a pen that is not auto-injector (like Convi/Gansulin). Auto pens FTMFW in my world 😀
