Automatic Injection Pens

Was this a peptide critic" video? He got deleted this week.

Do you have more alternative YouTube channels like this one? Hmmmm, wonder if videos in this category get flagged by the YouTube AI tool? Thanks!

Wow, I looked at the site and the price is 149? Since the convipens I still have are made in Switzerland rather than China, I'll have to bump up what I'm charging for them

I was drawn to the idea of an auto pen, particularly to help an elderly parent. But every single one I've picked up has proven extremely unreliable. I own 2 Birds, a Gensu2 (both side-trigger models), and a Convi (end trigger). Fresh out of the box, they all test accurately. Yet after about a week of use with peps kept in the fridge, none of them inject correctly anymore. On the side-trigger ones, I end up having to keep the trigger pressed while rotating the dial—that takes 2 hands and completely negates the point of an auto. As for the Convi, I need to press the trigger several times before the full dose goes in.

When I've asked others, the response is always “yeah, they don’t like to be cold.” Letting them warm up to room temperature didn't really fix it (and I'm not thrilled about repeatedly shifting the pep temps anyway), and neither did attempts to grease the internal parts. I may eventually test other carts that have silicone-coated plugs, but I'm not sure I want to spend more on them. The pens themselves already cost enough.

So, just a heads-up based on my experience with 4 autos. For reliability and price, a basic V1 is tough to beat. I also have a V2 and a Savvio, and they work fine, but my V1 slims have ended up being my go-to favorites.

Typically, the carts people go for are the siliconized (baked on) ones. There are also coated specialty plugs out there, but as far as I know those are meant for things like oils that would degrade rubber-style plugs, and they run about $2 for the plug alone. From what I've heard, Big time supply carries siliconized cartridges.

Before our order arrived, I picked up a handful of Linuo sample carts, and while pushing the plugs into the siliconized carts I was blown away by how smoothly they went in. Smooth as butter, almost ridiculously so.

I have been using a gansulin and I really like it. After getting used to it, I doubt I would switch back to manual pens. Pushing down the manual ones always feels clumsy to me, even the better-made options such as savvio.

These pens are genuinely good, and the side button is something I like. My wife, who has smaller hands, likes them more than the convipen.

Has anyone tried using spacers with pens such as the V1? I came across something suggesting that not all of the liquid might be delivered.

At [LINK] there's a breakdown of several pens. It indicates for every pen whether a spacer is required.

With both of them, I've never run into that problem. When you inject, do you press the trigger once or keep it held down? The cold argument is illogical — these devices are designed for insulin, and insulin is meant to stay in the fridge. Which compound are you putting in, and what needle gauge are you working with?

Since the convipen is getting harder and harder to source, you're right — grab them now while they're still available.

I've never found that explanation convincing, yet it's the same thing I hear every time. Here's what I do: keep the button pressed, use standard peptides (no oils, nothing viscous), and 29g pen needles (usually 6, 8, or 12 mm).

As I mentioned, for roughly the first week they perform perfectly. After that, the side-trigger models won't deliver anything unless I press the trigger and simultaneously rotate the dial with my other hand — which is awkward when doing GHK-Cu into the hip. And while they're still new, they push the whole dose through very quickly. That's something some folks dislike about the Birds. With the Convi, only a few units go in before it halts, so I have to let go and press the trigger again.

I'd be glad if this were just me messing up (even though 3 users have run all 4 of these pens), so any advice you can offer is welcome.

At the same time, countless people rely on Convipen regularly. The problems you mention are something I have never come across.

Nice. Should any of you have ideas, I'd be glad to hear them. Having them work dependably would be great. If that isn't you, though, then what you've written doesn't really move things forward. Plenty of others have hit the same issue — when I brought it up, the response was "yeah, they don't like to be cold," delivered like everyone already knows that. I've cycled through a few different carts on the theory that certain batches came with plugs that grip harder. I've verified the plugs sit the right way around, since I've seen people share photos of theirs installed the wrong direction. I've run them both with spacers and without. Small pen needles aren't what I use. Beyond that, I'm out of ideas.

Calling them junk isn't my point. They clearly have a big fan base (the Convi especially, for oils). They weren't cheap, and I'd really like them to perform consistently. Suggestions welcome.

I have a question for you: when you inject, is it simply a matter of pressing the button once, or do you need to keep it pressed until the injection finishes?

I'm not about to comb through this entire thread line by line, sorry. Could you just repeat your answer, or point me to the spot where you already replied?
