    I've tried all the pens on here except the gansulin & v1. I like the v4s best but you can't go wrong with any that Jeff sells here. Plus at 60 units per pen they fit in some real nice cases I bought on ETSY. If you get the longer pens at 80 units - they don't fit the case - too long.

      Exactly, that is why I said get one of each, shipping will kill you if you order them at different times. I don’t know if it is still available on this site, but the v1 was nice. I think the Xulin is supposed to be like a v1 on steroids. I had the Xulin before but only used it a week or so before my friend took it from me. I was just gifted another one by someone, so I am going to try it again. My friends take all my stuff 🤣

      @Commander There were no V1's on the site when I ordered. The only one I didn't get was the 3.5 simply because it sounded like it was the same as the V4. Based on the description, I don't know what makes the 3.5 different. I just wish he would have had the plastic travel (non disposable) pens as an option.

        Most people don’t like the plastic pens. I guess the v1 pens are no longer available. That Xulin pen is kind of a v1 on steroids, it is nice. I never was sure what a v3.5 pen was. I think there is a video on the difference between the pens.

          I have V2s, a V4 and a Xulin. I reach for the Xulin the most, its mechanism is the smoothest, just need more than two colors.

            So I received the injection pens I ordered from peptide critic. Took 3 days, which is much shorter than I expected so good job on that. I bought a V2, a V4, and a V3.5. They look cool. I have to do a little reading to make sure I understand how to set these up properly. Overall im very pleased with this purchase from peptide critic. From the community feedback and input to the simple ordering process and delivery, I really feel like this site can be called home for honest information and discussions about peptide research for my chupacabra. Want to say thank you to everyone who commented and helped me on my initial purchase and I can promise it wont be my last.

              Go onto the peptidecritic YouTube channel & watch the videos specifically on pen - I think there are 3 or 4 different ones - if I had seen them before I started with pens I would’ve saved myself a lot of time & money.

                @Nuncles IMO the v3.5 feels just a bit sturdier than the V4. V3.5 is a bit shorter. The clear piece screws on w/V3.5 instead of clicking into place on the V4 - this is a very subtle comment but one that is important to me and that is the clear plastic 3mL vial pc on the V4 clicks into place showing the scale of how much peptide is left right in line with the dial # which makes it easier reference for me. Mechanism is about the same. Can't go wrong with either but my personal preference is the V4.

                BTW... also got some V2 pens for my wife because she likes the colors but I do not like those as well - they just feel "cheaper" to me. I do use Xulin for TRT (Blue) & Reta (Red) which are very classy pens - makes me feel special using those. But still through it all - my preference is the silver V4 - great great pen.

                  @matthewwalsh I appreciate the insight on the V3.5. I'm kind of glad I passed on it. Personally, I think I like the "click" better than the screw in vial holder. I wasn't that impressed with the V2 but the bar had already been set by the Xulin and V4. I feel that the V4 seems to be the sweet spot right now. Yes, the Xulin is smoother, but $20 smoother? Probably not. But hey, if one's budget is more in line with Mercedes than Toyota, get the Mercedes.

                      3.5 would be my favorite right now if I had to pick one, but all 3 are 100% better than insulin syringes

                        Now that I have a bunch of pens and multiples of each type, I find i am gravitating to specific ones that consistently run smoothly and consistently. At the moment, I am running a V1 and V2 that are flawless. One of my Gansulins is sluggish pushing peps across multiple carts. The other two seem fine. I don’t love the Xiulins if I am being honest. They seem ‘stickier’ than the other pens I have and can be hard to get started.

                        It might be good to make a video on maintaining and tweaking pens to keep them running smoothly. I have no reservations about taking a pen apart as long as I know how to put it back together.

                        I will order some V3/4’s when they are back in stock.

                        If I haven’t liked your post, no offense. I have exceeded my daily allowance.

                          @ResearchCat To me, the 4 is the best. I like the Zulin, but like you say, it's a harder push.

                            The way the pens are built once taken apart they cannot go back together.

                                Thx. That was my assumption, but I wasn’t sure. I have seen that tool to take them apart, but I have extensive experience disassembling things that cannot be re-assembled and you often don’t find out until it’s too late. 😉

                                  The tool you are talking about doesn’t take them apart. It only unlocks a locked a gansulin/convi pen

                                      Almost every pen that I looked at so far is pressed together in some way or another making it impossible to be taking apart with wrecking them. It just must be a cheaper way to assemble them.

                                        Youre looking at the wrong pens. Even the ones on Amazon or AliExpress, which typically have a chrome band around the center, they separate into three pieces. The cap, the cartridge holder, and the injector unit.

                                        I have ordered about 11 of them off AliExpress because they are cheap. Ive seen many complaints about them being unreliable, and I found a few of the V2 units that were indeed having issues. However by inserting a single small 3d printed part to add tension to the spring mechanism inside, they all run mint now.

                                          Stupid question. Ordered 3 V4's from @randy today and wanna ensure I get the right needles. All the versions take the same type/style, eh?
