    I think whatever works best for you is probably fine. I have tried different needles and have settled on 30g 6 or 8mm. I like the 31g but anecdotally, I think maybe stabbing the vial to fill the syringe may dull the needle a bit and cause it to catch a bit when injecting. I could be off base but i find, for example, I don’t feel 31g pen needles at all as compared with 31g syringes. Fun complication: my state restricts shipping of ‘medical supplies’ so some vendors won’t send me syringes or other items without a prescription ‘for my safety’.

    WRT GHK-Cu, yeah, I have used wolverine stack for a few months, and switching to GLOW, it definitely burns. And diluting helps.

          RIGHT? The glucocare ones we suggest are fine but the novofine... "Its not just an injection. Its an experience"

            I agree the glucocare and clear choice are great options but for those who want the Ferrari, well then Novofine is the one

                  I’m assuming that these are knockoffs? The box looks completely different than most others I’ve seen.IMG_1576.jpeg

                    no they are asian market. They arent the same as the novofine plus though.

                      When using the V2 pen with the retractable end pin cover, Are the Novafine plus 4mm pen tips long enough ?

                        I just checked...wasted a needle. Yes it works. I forget about that "feature" on the v2. I've never actually used it.

                              I recently got a box of 500 "PIC insupen 34g 3.5mm" and they are probably the smallest needles on the market; you don't even know that it went in, and they never cause bruises!

                                  I am terrified of needles and started my peptide treatment last week, I'm using the Novafine plus 4mm and the V2 pen, I literally feel zero pain !
                                  The pen is awesome because I can't see the needle, this and all your YouTube tutorials has made this experience fun and exciting.
                                  @randy Thank you for all you do for the community , I have learnt so much ❤️

                                    I watch it go in. I hate needles but feel this is my punishment for getting old
