Pen vs syringe in the office.
-
I have a bunch of pens I use daily, including V1’s, V2’s, and V3’s. I like the V2’s best but they are all about the same to me. The Gansulin is my favorite, and the Xulin pen is good.
No idea how long they last, but the QoL improvement and cost relative to syringes probably makes the break even less than a year and they will probably last much longer than that.

@jackie I have 3 now and I love them. I still use the other ones for color coding and to see how they operate. (And things like KLOW and NAD+ are best injected slow, imo.)
-
You really can't go wrong with your first. I'm embarrassed to admit I now have a dozen of them in various stages of use and only one has given me trouble. I must have viewed the Gansulin on here 50 times just haven't pulled the trigger. The 2 Xulins seem the most refined- by just a bit.

I’ve read that pens last 18 months or 300 injections, whichever one comes first.

@ResearchCat probably a dumb question but do you have to use a new needle every time?

Yes! You don’t want to risk infection -
Yep. I go through about a box a month. sometimes more.

How would an unused pen go bad?
And even a pen in use, I'd have to imagine would last for at least 5+ years (and thousands of injects) before the parts would start to break down

@ResearchCat ok thanks. Is 31 gauge 3/16 inch 5mm a good size?
-
Yeah, apologies for being long winded. Basically my question is does a syringe, filled with peptides, travel well? Or dont bother and invest in a pen?
@phiberopttic PENS!!

-
Wow!! Impressive!! I feel completely inferior. The past two nights, I've loaded up cartridges, packed everything up in the super handy Peptide Critic travel pack; adding a spare syringe, but in case... then the next day, after I cant make the pen do anything, I used my spare syringe to pin the doses. Does anyone have a YouTube recommendation for how to inject with a pen?

Its a bad idea. I know that. But when I am in a hurry in the morning to inject into my girlfriend's big brown beaver, I will go a few times. I have never had a problem.
BTW, the Novofine brand is by far the best and slips in easily even multiple times.. Must be the coating and/or the grind.

I just started with 6mm for GHK-Cu into my reasearch beast's butt. It seems to diffuse better than 4mm's - no topical welts. And I don't know why anyone would not use the slightly longer needle to certaInly get it past the skin layers.
The asian made ones on Amazon are pretty cheap. -
@phiberopttic PENS!!

@mrjoshua44 What label maker and labels size are you using for your pens?
