Trouble with refillable injection pens?

[LongGameLarry]

I got a handful of these reusable pens to use with some research compounds. The first one I tried didn't seem to work, so I took it apart and saw the plunger was stuck. Since then, I've had similar problems with about half of my pens. The plungers are jammed, and I can't figure out how to fix them. Now I'm worried I'm not getting the right doses. Has anyone else had issues like this with pens?

Which pens are you using? I like my metal pens a lot.

Pens seem like a pain. Is there any benefit to using them versus regular syringes? Especially if you're just doing daily injections?

I used to think pens were unnecessary too. Now I won't go back to syringes. I can load several vials into a pen cartridge and it's so quick. I'm on several peptides now, and it's such a breeze to inject. Way less waste!

I didn't mind injecting with syringes initially. Felt like a science experiment. But then I tried a refillable pen. My weekly shot is now super quick. I keep the loaded pen in the fridge door, grab it, inject, put it back. Once a month I load up a pen cartridge. Quick and easy.

I'm also curious which pens you're using. I have two different models and haven't had any problems with either.

I'm sure I'll run into a pen that fails eventually, but not yet. I've used several different brands, and they've all worked fine so far. I test them with water-filled cartridges when I first get them. If you have a decent scale, you can check the dose accuracy.

 

[Ozzy]

Yes, for daily injections, they're much easier to use. I use them weekly, too, just because they're convenient.

Here's a trick I saw: to prevent blowing out a cartridge, fill it while it's already in the pen you'll be using.

Sounds like a good way to test my pens! Thanks.

 

[LongGameLarry]

Will do this. I really want these to work. I hate prepping shots all the time.

I have one of the V1 models.

To clarify, I weigh the full water cartridge. It is about 8.5g. Then I weigh some paper towels and zero the scale. I reuse old towels, cartridges, and needles with distilled water. I inject 5-10 doses into the towel. You'll see differences that show you how accurate the pen is.

If you have a good scale you can measure the dosage. Bubbles in the carts can be a problem, so get those out. If they jam, silicone lubricant may help.

I love my pens. I take several peps every day, plus some once a week, so pens save a ton of time. Plus, there's less chance of contamination than drawing up a syringe daily. Also, the needle isn't dulled from going through a vial, so it's more comfortable.

 

[LongGameLarry]

I had one pen that broke apart mid-injection, but I don't use it anymore. All my other models have worked well. I really like using pens.

 

[LongGameLarry]

Meh. I'm keeping my autopens.

 

[Ozzy]

I think pens hurt less to inject. A regular syringe needle gets dulled by going into the vial first. With pens, the needle is always new. I haven't had problems with pens.

I guess my last post was goofy. It didn't work right. But it goes to show how much things have changed!

 

[SemaGeek]

Well... I said I'd consider it. On the supply side, totally doable. The real bottleneck was always those plastic injection pens - swap for syringes and vials and done. Lilly's already handling it that way.

The key is whether you're filtering or injecting daily. If you're using thick oils or large proteins, filtering could be an issue. If you're not filtering and inject once a week, it may not be worth the time to load a pen. If you're doing many shots and multiple pens, it becomes an assembly line.
