@karakurilabs They don’t state anywhere that they’re non-sterile? [image: 1774520737577-be92b265-f0ae-439b-a8ad-3de563dddb8a-image.jpeg] They’re the same ones I use; I have ordered .5ml & 1ml.. no issues. They’re smooth and glide a lot better than others I’ve tried

@Randy Thanks for the response. Higher dilution is a great idea. I'll definitely dilute the next batch as the current research amount is 10 units. I do count to 10 after pushing already, so I'm good there. I think I knew the answer on sterilization....don't even know why I asked...

@ussliberty Got mine today- should have ordered at least another one- very nice!

With regular pens, you have to press the plunger manually to dispense the product. Auto-injectors are spring-loaded, so you press and hold the button and the pen smoothly dispenses the product. I think they are both accurate. The problem that you describe is, imo, a separate problem. You are trying to dispense an amount that is barely greater than the margin for error. If you are injecting 3 units, and you lose .5-1 unit to inaccuracy in measurement or something else, and then you lose a little more due to dripping or failure to inject completely, you could lose a substantial amount of the product. If I inject 200mcg in 3 units and lose 1 unit, I am losing 66.6 mcg of the stuff. If I am injecting 200 mcg in 10 units and lose 1 unit, I am only losing 20 mcg. It might make sense to dilute you peptide to make it easier to get accurate and consistent measures.

Hi all, just joined the forum and I must say it’s an incredible resource. However I am at the stage where I am looking around for pen supplies and pre sterilized pen cartridges, however I am having a hard time finding any which are located within the EU, does anyone here perhaps have any suggestions for a good supplier? Thank you all in advance.

Thank you!

Lyophilization itself freezes the peptides. As long as they're not reconstituted you can freeze them.

Anyone using the Gansulin with 12mm 29g needles and Testosterone Cypionate? I use a manual pen, it is a slow steady injection with warmed Testosterone Cypionate. Wondering if it can handle the slightly more pressure with oil based injections. Thanks for any info. -Phil

@diegoc What Diego said. Buy some v2s and and try it.

So are needles and thats why they share them in San Fransisco

Having a few pens is a good idea for those peptides you do constantly, you can have 1 pen that you swap vials but its a pain in the ass. Ive injected myself so many times with out priming the pen, lol

Thanks Randy. I was wondering what the exact amount was. I guess I had more loss than I thought.

@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
