man i've been looking for these too. pinning with a regular syringe is fine but a pen just makes the whole "morning routine" so much smoother. i saw some guys on etsy of all places selling 3d printed cases and kits for them lately.

check out aliexpress or even ebay for "reusable research pens" - they usually call them "magic pens" to get around the medical filters lol. they work pretty well for most 3ml cartridges but u gotta be careful with the quality of the internal gears.

i think pepsupplies or some of those bigger peptide sites started carrying a "v2" refillable pen recently. it’s a bit more expensive than the chinese ones but it feels way more solid in the hand and the clicks are actually consistent.

just a heads up if u go this route... filling the 3ml cartridges is a bit of a learning curve. make sure u don't trap any air bubbles or your dosage is gonna be all over the place. once u get it down though its a total game changer.

honestly i love my pen for traveling. it looks way less sketchy than a bag of needles and vials if someone accidentally sees it in your fridge or bag. plus its way easier to stay consistent when its just a "click and pin" situation.

u can actually find metal ones on alibaba that feel like a high end fountain pen. they take the standard insulin pen needles too which are super cheap. just search for "reusable insulin pen" and look for the ones with a clear chamber.

be careful with the conversion! since peptides aren't concentrated the same as insulin (100iu/ml) u have to do a little bit of math to figure out what one "click" actually equals in mcg. i had to make a little cheat sheet and tape it to my fridge lol.

i've seen some guys in the reddit forums mention "toadspens" on ebay. apparently he sells kits that come with the cartridges and the pen together which is nice so u don't have to hunt for parts separately.

definitely worth the investment for the convenience alone. i keep my tirzepatide in one and it makes the weekly shot so much less of a chore. just make sure u label them if u have more than one pen in the fridge so u don't mix up your growth with your fat burners!

does anyone know if these pens hold up well with the thicker bpc-157 blends? i tried one with a super concentrated mix and it felt like the plunger was struggling to push. maybe i just need a bigger needle gauge?

man once you switch to the pens you can never go back to drawing from vials every morning lol. check out the "v2" or "v3" metal pens on ebay or etsy. they’re usually listed as "research pens" or "magic pens" to get around the filters but they fit the standard 3ml cartridges perfectly.

i got mine from a seller called elviralabs on ebay but i think they're on etsy too. they usually come as a kit with the pen and a few empty glass cartridges. just a heads up - make sure you get the metal one. the plastic ones feel super cheap and the clicking mechanism for the dose starts sticking after a few weeks.

honestly i just use a refurbished novopen i found online. they're tanks and the dosing is way more accurate than some of the generic ones. you just have to buy the empty 3ml cartridges separately and fill them yourself. it takes a minute to get the hang of filling the carts without bubbles but it's a game changer for travel.

be careful with the generic "80 unit" pens if you're doing tiny doses like ipamorelin. some of them aren't super precise at the very bottom of the dial. i prefer the ones that click for every 1iu or 0.01ml so you know exactly what you're getting. also definitely grab a 3d printed "cartridge holder" from etsy to make filling them easier - saves a lot of wasted product.
