Left over
Iv looked online but I'm a bit confused. I have a golden dose left in a 2.5 pen, I'm currently using a new 2.5 I want to up the dose manually with 2.5 from new pen and 0.5 from golden dose to make my current dosage 3.
My question is how do I do that with a syringe? What's the actual number I fill to. Very confusing when reading online, mainly because it seems to explain larger dosages more in depth.
Thanks.
