My better half is currently using the standard insulin syringes, but for some random reason, injecting is now semi-painful for her. I bought her some slightly more expensive syringes thinking it might be that, as the peptide hasn't changes or using a different BAC etc, but she's still saying it's suddenly now painful, not mega painful, but uncomfortable. I'm using the same syringes and nothing has changed for me.
So after changing those syringes with no luck, I thought maybe I could buy her a gansulin/convipen (if I can find one in the UK), and get her to use the needle tips that are used for that, as she used to use the lily mounjaro pen and tips for months on end no issues.
So my question is, she currently uses per week, glow, tirz, reta - 3 vials. Is it practical/straight forward to make up 3x cartridges instead for these pens (I've never used one, but seen on youtube how to load prep a cartridge), and then swap them over out of the pen when needed? I didn't know whether the plunger mechanism was sort of locked into a postition for how much had been used on the last cartridge etc, so if you wanted to load in one 25% used vs one 50% used etc, whether this would cause any issues or how you would get it 'loaded' so to speak? Would you just keep turning the dial and depressing the button until it wont go any further, and then you know the plunger is in the right position?
Does anyone here use one pen for multiple peptides, or are people running multiple pens instead?
