When to use a pen and when a syringe?

[Kyli]

Hey everyone,

recently I bought some pens for my peptides. But now I was wondering, when does it make sense to use a pen and when not? Does it make sense to use the pen for reta, so for a vial that lasts for a long time? Or for semax / selank - so daily application? Or for my 5-Amino-1MQ where I inject 2x day and the 50mg Vial lasts 5 Days. So I would have to refill a new cartridge every 5 days. Does it make sense? Or isn't the work worth it?

I'm currently wondering the same thing! I just ordered some pens as well.

There is a certain amount of loss associated with every syringe action, you loose some units in the dead space, pens tend to only suffer that loss once as they reach empty. So pens typically get more out of a vial when there are more pins even though their end space loss is typically higher than a syringe. While a capsule is a little bit more hassle and expensive its also quicker to pin with and if your filtering anyway capsules just make a lot of sense rather than buying additional sterile 3ml vials, as a workflow its one extra vent needle.

For me, the fact that a cartridge holds up to 3 mL already rules out a few peptides.

I also tend to mix a few peptides in one syringe, so anything that would normally go into a blend is a no. Same with anything that requires larger doses, like SS-31 at 5 mg or MOTS-c at 5 mg.. I wouldn’t want those taking up that much cartridge volume.

So that actually doesn’t leave me with that many obvious options. Pens seem to make the most sense for smaller, consistent doses of something used on its own: maybe GLP-1s, cagri/elora, possibly GH.

For me, pens are elite for daily & weekly pins like Glow/Klow/Wolverine/Tirz purely for convenience reasons.

1. Pen tips require less storage space than full noodles
2. You also get more mileage with your sharps containers
3. I'd say pens are typically more hygienic due to absentminded things like putting your noodle down on the counter after pulling - you wouldn't need to put your pen down, for example.
4. They encourage filtering, which should be in EVERYONE'S recon routine

They're not for all peps due to the 3ml size constraint, but they're definitely convenient.

The worst part to pens is the learning curve if you're used to using noodles - but it's the same learning curve as using noodles themselves, so not too bad. PLUS, automatics are just lovely - if not easier than noodles.

watching this thread cause I have some pens enroute as well. I mainly ordered them so I can pin my butt 🤣

If I had the pens, I'd put almost everything in them. I only have 2 Convi pens. They have Tirz and KPV for now. Everything else is syringe. I need to buy more pens.

what exactly is an automatic pen? aren't they all auto cause we only have to push a button? I've never used a pen yet...have some on the way . I ordered 3 V2's

I've been too pre-occupied with stacking...I see I need to give pens a whirl for the daily jabs... 👍
