    @kbranton - to add on to what @seadracos advised... I agree that 31 gauge is about as thin as you want to go for good outcomes.

    If you are using an automatic injection pen like the Gansulin 2 (one of the ones I like the most), there are a few additional practical tips that make a big difference:

    Prime sticky cartridges: With new cartridges, the rubber stopper can stick to the glass from the manufacturing/autoclave process. Manually nudge the stopper forward just a tiny bit before loading it into the pen. This prevents the auto-injector mechanism from stalling against a stuck stopper.

    Test different needle lengths: Depending on the specific medication or fluid viscosity, varying your needle depth can change your results. A 6 mm needle works well for many standard subcutaneous injections (tirz in my case), but slightly thicker solutions or different body sites might perform better with an 8 mm needle to ensure proper depth - I use these for KLOW.

    Hold the post-injection count: Always keep the needle fully inserted in your subcutaneous tissue for a full 10-count after the mechanism finishes clicking. Automatic pens push fluid quickly, and pulling out too soon often leads to leakage or lost medication on the skin.

    Have fun on your new adventure - pens are well worth it for dailies.

      @uxu - Gansulin 2? Do you mean Gensupen 2?

          @uxu - I haven't tried one, but the side button is throwing me off. Since you prefer it, what are your thoughts....and was it natural to get used to?

            @Blueeyedme They break too been there. The autopens that are not Gansolin tend to break after about 6 months and they do it on the last dose at least thats my experience. The internal clutch breaks. Keep in mind I was using them everyday for months so maybe thats to be expected. It also happened to my Zulins. I am using the crap out of them. My Gansulin and the other pens V3 Ultra, V4, and V2 just keep going.

              @Stevepep - thanks, I have a few Gansulins and a few Novo 4's. I'll grab the new battery one that's floating around...I think Jeff has been testing one here, Daro and Riptide have been testing as well....meh..something fun and new.

                  @Blueeyedme - The side trigger on the Gensupen 2 is surprisingly easy to get used to, and it actually feels more natural than using an end-plunger. You just hold the pen body with your fingers and slide the trigger with your thumb to release the spring.

                  It does fire with a fast, snappy injection compared to manual dial-and-push pens, which can feel a little abrupt the very first time you use it. However, it does not hurt or cause any real distraction, and you adapt to the timing quickly. Overall, it works really well once you get that first injection out of the way.

                      I’m the same as everybody else. The Gansulin has been amazing. I try to keep a good rule of thumb that the injections should be less than 30 units for best comfort. Ideally, you keep it around 20 to 23 and it’s like butter.

                      They’re also amazing for hard to reach places like if you wanted to inject in your back or your butt

                        The Gansolin is by far the best. Convipens are less expensive but are prone to breaking in my experience. Peptide critic has a big sale on Gansolin right now for $69 don’t waste your money on anything else for the $20 savings the quality won’t be as good. https://community.peptidecritic.com/topic/3688/store-prices-slashed

                        If you look back far enough on this forum and a few others, you will see where I cut bith the Gansulin and Convi pens apart and posted pictures. They are the SAME pen made on the SAME assembly line. The tooling and casting marks clearly showed that.
                        I didn’t speculate, I did use chatGPT or the internet to come up with that - I actually cut them apart. But everyone else who says they are different has not done that, why?

                          @Commander interesting they look different I guess the internals are the same. I have both they don’t look the same in appearance. The dial and indicator are different. I must be hard on pens I loved the convipens at first but the clutch ends up breaking after long term use. I must have a really good Gansulin it just keeps going. I was under the impression the convipens where from Bangladesh and the Gansolin China

                            This has been covered multiple times on here and other forums. I actually cut them apart myself, I didn’t look at pictures on the internet, I didn’t repeat things I heard or read - I BOUGHT BOTH PENS and cut them apart myself. I posted the detailed pictures of everything.
                            You have the pens, cut them apart yourself and post pictures of how they are different- put your money where your mouth is -I DID.
                            The only difference was in the cart adapter, and the difference was that they both came with 2 different ones, and I posted pictures of that too.
                            This board is good because it has good information, but is is getting mucked up because people like you keep posting just to post and you put BAD information out like this. Again put your money where your mouth is and cut the two pens apart and post the pictures. But you won’t, you will reply with multiple posts about this our that and why you don’t need to because you know this or that… bla bla bla… cut the pens apart and show is the difference. I did.

                              @Commander I wasn’t arguing at all I believe you I said the internals are probably the same. I believe you not arguing at all. No need to get your panties in a bunch. I don’t even care to be honest I was just posting my experience as a user of both pens. I have two convipens that broke maybe it was user error or how much they got used by me.

                                Just make sure you have at most 31 gauge pen needles. 32g pen needles seem to be just too thin for the gansulin to deliver accurately. 31g is fine for low viscosity peptides. I wouldn't use it for any oils, and personally I find that all pens deliver better when they're at room Temp.

                                I thought I had a broken Gansulin when I switched to a 4mm (32G), but switching back to an 8mm (31G) showed me it still worked.

                                  @Stevepep - It's the AEI-01/03 digital bluetooth injection pen, made by Hangzhou Qiantang Longteng - which appears to be a legit FDA (510)k approved manufacture for other injectable devices. Some are calling it an electric Gansulin because they look very similar - but not related at all. STG guys say the next production run is later this month and hopefully see stock by January. The best link I have leads to Riptide's TG where he has a bunch of photos and testing videos. Daro has kept his in the refrigerator for a month now - test dosing everyday and hasn't needed to recharge....that's about all I know.

                                      I have 6 Gansulin and 2 Convi. I believe commander saying they are identical as he’s cut them apart. In my small sample size of using these pens daily for 6 months now, some of my Gansulin stick but my Convi surprisingly have been smooth. All are kept in the fridge and I use 31g 6mm pen needles. Maybe it’s possible that there maybe a quality consistency across different batches?

                                        I will say this. Convipens aren’t sold on peptide critic Jeff said why he tested them etc I believe. For what we get for free on this site me personally I am buying a Gansolin from peptide critic before I buy a similar item elsewhere. That’s just my opinion. Let’s support this place that does this for us for nothing might as well shop at the store

                                          I was getting frustrated with my Gansulin and my ConviPen. Both would stop after 4 or 5 units and do it 3 or 4 times to get an injection in. Then, I read about the needles. i was using 33g. I ordered 31g and they both work great now. No issues!
