@Randy thanks. Nice to finally e-meet you. You’re all over my YouTube feed.

I see that the v4 are sold out. Is there difference with these 2 versions?

A lab owner I'm friends with who's much smarter than I am did the testing to debunk any of that.

use the smallest one possible to avoid waste. The filtration capacity is as follows. 1ml and under 4mm 10ml and under 13mm 33mm 100ml and under Use 13mm and purge it with air or 15iu when your done to reduce peptide waste. Its rare im doing less than 1ml but i do have 4mm on hand.

This morning I let it sit out as I sipped my coffee and then I changed the needle. It worked! Thank you. The needle is so much better than the disposable insulin ones, I couldn't feel it! I was a bit worried to push the button, that it might just be on the outside of my skin! LOL

what was your order number. Chances are you got UV sterilized as we had a thousand of those come in at one point.

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!

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.

@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

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
