@Randy Appreciate the update. I'll be on the lookout.

My Gansulins are spot on testing with a 31g syringe.

@Stevepep So this? https://peptidecritic.com/store/peptide-critic-research-pen-blue-copy I believe it comes with built-in cartridge and has the same loading process as Jeff's video tutorial, right? @randy?

@Nuncles Great idea here you go https://community.peptidecritic.com/topic/3255/poll-what-s-your-favorite-peptide-pen

Got them!!

@brandenscheidecker Were you using the V4 for your L-Carnitine?

@diegoc Agreed. Sometimes the gear-chasing rabbit-holes can bum me out. I haven’t had any issues with the bulk pen-carts from Amazon nor the 50-pack of LocoFiltrs nor the Furwey “sterile” empty vials… but if I grow a 3rd arm, they’ll be the reason why.

@STATIEEIGHT it was already in my "Saved for Later" on my Amazon.

@mrjoshua44 I have a V4 and a V2, and the Ultra is my new favorite. It’s not quite as smooth as the V4, but I like the enclosed pen cap and the smaller size.

When I get my monthly compounded Tirzepatide from Mochi, it always comes in these really nice travel canisters and comes with reusable ice packs. Well, these canisters are perfect for keeping your pens nice and cold and will keep them cold for a couple of days too.

@STATIEEIGHT said: @Commander I only know this because I’ve been playing around with it for a while now - only actually pinning for a couple weeks though - ARA-290 has possibilities if it is blood flow/nerve related (only from what I’ve read) especially in diabetic related problems/macular degeneration. Im not using it for that reason but wear glasses so am interested if I notice any difference- I haven’t been doing very long but will post if I notice anything. Eyesight definitely improves with lowering of HbA1c though - I can personally vouch for that one. Something else to look into anyway - and add to your warchest maybe . Keep me posted

@Stevepep You're correct those are autopens so completely different. I should have been more clear in that I meant quality/weight/feel of the v3 ultra is up there with those pens.

I primed and used bac water. I pushed the plunger to the point of a couple of drops of water was coming out. Maybe the vial, but it dispensed perfectly on the V2. Since it is non-returnable, l'm stuck with the V4.

@ResearchCat I always hated the thought of needles in my body until this year, now I'm just like you...I watch closely as the needle breaks the skin...I'm almost fascinated by it.

@EXTROPIAN said: @cc4part41 What we really need is some kind of micro ekg skin nerve detector or pins laced with Lidocaine. Now you're talking. Stick and pray isnt working great.

@gym.rat That is great to know. The post sounded so legit I started just taking the blend and adding another shot of TB500

Flat base tips do not work with the hide a needle feature caps.

Nice! Thanks for the ideas. Looking for something more hidden, but I’ll see about these holders

@damic thank you so much. I appreciate your help.

For those using a 3 mL syringe, what size and length breather needles do you recommend? Also, what size and length reconstitution needles work best?
