Thanks, will do. That cart only has 1-2 shots left. My two new gansulins, Semax, NAD+, and label printer all hit the porch today, so today is a good day. More research homework to do tonight.

Ive always been against having one pen and multiple cartridges. Ive seen people accidentally do reta instead of tesa etc. A couple v2 pens and a pack of carts from our store, and some 4mm needles from amazon would be all you need https://peptidecritic.com/store

@MyB Ah! Gotcha, that makes sense, thank you!

@SoCalGirl There are some content creators who will swear up and down that mixing peps or buying blends will destroy them, but it just isn’t true. There is a small amount of degradation(1-2%) over a couple months, but for the most part it’s fine. And you can find videos that show what @nosaj posted with longer explanations if you’re interested. That being said, there are individual peptides with shorter shelf lives and some that require more careful handling.

Randy, I will have to give that a try- not anything I'm into yet with the 3d printing but I may be soon!

Nice! I have a v4 coming this week- very excited to see how much better it is than my beginner one that works well, but doesn't seem as quality as these!

@MyB Yeah, not to get political, but it’s funny that the states with the most ‘free’ health care also have the most restrictions. In MA, anything to do with diabetes or deemed to be medical related, from syringes to Hospira bac water, require a prescription, and sell for way more than on the open market. Amazon is hit or miss depending on the vendor. There are places that will ship, but pricing isn’t always great and availability of your preferred product might be limited.

I use these 30 gauge 1/2 inch luer lock needles as vent needles.

The Alcohol trick worked a treat. I'm really happy with being able to rotate cartridges and queue up the plunger within a click/U. It's funny, the lady and I both have 4 pens now. How this "hobby" grows.

Is it ok to store unused 30ml BAC water vial with a vial spike adapter attached? Vial spikes for reference: https://peptidetest.com/products/universal-vial-spike-with-0-2-µm-air-filter https://peptidetest.com/products/vial-spike-adaptor-for-20mm-vial-neck-compatible-with-hospira-30ml-vials

@Randy Thanks!

@SEOCoder spot on. I do 6mm for glp because i really want to get the "fat juice" in there but 4mm is plenty.

Wait till you see the puck on a 500mg bottle ;). Size doesn't matter

Droplet 29g 12mm pen needles may be the go to without spending a ton of money for specialty needles of greater length and bigger bore size. [image: 1771984686390-screenshot_20260224-175706.png]

Today’s fun was reconning 10x10mg SS-31 vials and loading them into 2 carts. Overall clean run with very little waste. I did 2 lines of 1 into 1 … with 5 vials each to keep it moving. Lesson: Make sure your vent needle doesn’t end up under the fill line or you may get backflow up the vent. I flipping love the Gansulin pen and need to get more of them. I also tried the 32g 6mm pen needles and they are sweet! Charlie the research cat doesn’t even feel them. Is there anything special to do with a loaded cart you aren’t using yet? I just put it in the Gansulin pouch. Might throw it in a little baggy. (I purged the excess air.) [image: 1771609356921-att.uojhjkoy2qc-2mehxq6b88trqpm8xyrq_61qjyqia3c.jpeg]

@ResearchCat Much appreciated.

They're slightly shorter and thinner. They wont fit in any of the pens we have. The pens that use them are harder to find and disposable.

Jano has a fee to put other vendors names on the test if you are the original tester. My point is you dont trust their tests. its one bottle from a batch of 30,000

Oh no! Those were a limited run. Any case we do is limited to 30 except the peptide critic 6 vial cases.

Thank you both!
