Remaining product in pen cartridge
-
It depends on the pen. It ranges anywhere from a few units to 10. But I've found that many pens get inaccurate when you get close to the end. For example, if I have 20 units left and try to inject 30 units, I would expect the pen plunger to stop at 10. But some don't and you may get a different dose than 20 units. Again, depends on the pen. As a rule of thumb for me, when the cartridge gets to about 20 units, I just take it out. I either toss it or pull the rest out with an insulin syringe.
Edit Some pens like the Gansulin and Convipen don't allow you to dial more of a dose than is left in the cartridge.

I know it shouldn't bug me as much as it does but it would be nice if the cartridges came with a slightly convex plunger top to get out as much product as possible. But regardless, I still love my pens.

@HockeyRat, you would lose accuracy because the volume per click changes below where they stop.
Just use a syringe and pull out that last bit, and then you know how much you have, too.

Loosing that little bit at the end is a small price to pay for the convenience of a Pen. Long Live The Pen!
@Commander --- And, what I feel is more accurate dosing from the pen versus my "eyeballing" the syringe.
-
Exactly - as long as the pen IS actually accurate & remains accurate- I’ve got to the point now where I keep a little test kit in an old sunglasses case jutting to test & show people how to as well as actually reconstitute etc before they start but just using tap water.
I’ll be getting a stuffed rat
& starting a YouTube channel before long.

I know what you mean my eyes are bad and every time I try to stick the syringe in the little stupid 3ml vial half the time I ended up sticking my damn finger. I am blind as a bat now. Anyone know of a Peptide that helps your vision?

@Commander I have heard SS-31 helps some people. I think the dosing is pretty high though for eye help. I was reading somewhere they even are testing SS-31 as eye drops in human trials.

I pray it works. My eyes are getting worse by the day

@commander I have tried a couple of supplements and some peptides that allegedly may improve eyes/reduce floaters, but I can’t say that I have noticed any difference. My vision in one eye is 80% better since getting the lens replaced due to scarring (annd a subsequent capsulotomy) even with the floaters. Doc doesn’t want to do laser floater removal due to risk/reward profile.
Note that the typical subject for IoL/lens replacement is 80+, so while risk is very low, if you are much younger, as I was, you have a lot longer to live with any complications or side effects that might occur. And it is still probably worth doing. Get the best you can, and only do it once.

@Commander my vision went downhill the last year and I did something that had it improved, like floaters disappeared, the clarity increased. But I was doing a lot of things together. The main suspects are (to me) Carnosine powder, HBOT sessions, red-light sessions. HBOT actually makes vision worse right after the session, but then it quickly restores and maybe improves. Carnosine is a known antioxidant for eye tissue. Also I tried Visoluten peptide just recently, it actually had a similar effect as HBOT making vision worse, but then better after stopping the treatment.

@vpeptides HBOT has been used for several eye diseases. I didn't know it could correct a vision issue that requires the use of readers. How are you using red light on vision. I am intersted, I couldn't deal with readers so got contacts which was life changing. I tried Carnosine but noticed nothing different really

How are you using red light on vision
Not specifically on vision, I was using a setup of 6 300w red lamps with reflectors around a swivel chair before HBOT, eyes closed, no glasses. But I know that its ability to "boost" mitochondria via cytochrome c oxidase is known to affect vision positively.
I noticed a long time ago that after the dark winter months, going out and spending time at the sun, just facing the sun with my eyes closed, improves my vision. -

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
