Which pen to buy
-
@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.

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.

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.

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

@ResearchCat
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.

@ResearchCat
The tool you are talking about doesn’t take them apart. It only unlocks a locked a gansulin/convi pen -
Oh, thanks. I guess I misunderstood what the OP was saying.
-
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.
@Commander
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?

@hunt_ak go to the research supplies section. My favorites are in there.

On the v4 if you want to use the hidden needle feature the fatter based models wont allow you to put the cap on and hide the needle. The ones in the research supplies will.
I have never hidden a needle though.

I have no idea what you are talking about by “you are looking at the wrong pens” I am talking about completely taking apart a pen to get to the internals. No shit you can take the cap off, the cartridge holder off.. you can be blind and see that. But you can’t take the pen completely apart to get to the internals. And the spacer so the clutch doesn’t slip, really, that is common knowledge and talked about everywhere.
So I really don’t understand what your post is saying, especially because it seems to be commenting on my post that is talking about completely dissembling a pen that is pressed together… -
@commander its been my experience, taking apart a lot of old equipment when I worked for a restoration company, that pressed together parts generally tend to be one shot and done. I agree with you, I dont know if the intent was to not have anyone able to repair and put back together. It sure seems like it was though. Generally you have to fight so hard to get separation that sometimes you destroy whatever it is you are working on. The old saying of anything man built man can take apart is true, it that dont mean man will get that same piece of shit back together again without double sided tape or marine grade JB weld. I dont follow that dude either that does seem to be responding to your comment. I bet he used too much semax. I wanna make a Dihexa nose spray
-
I actually did take apart the pens. I had to cut them apart. Most are also plastic welded in certain spots..
But by all means take then apart (like I did) and post the pictures (like I did).
I would love to see some more pens apart and don’t have time right now to do it
