Does a pen have only a certain amount of times you can use it?
@Lovinglifeand
According to the manufacturer, yes, you should use it four times only and throw away the 0.8ml which is left. (That's one full dose plus a third of a dose - the famous "golden dose")
According to almost everyone who has to pay for the stuff, you can use it for much longer.
My own view is that if aseptic precautions are observed each time, I'll use the contents of each pen however I choose. But it has to be an individual choice.
I am acutely aware that most people were only ever willing to use the pen as per Eli-Lilly's guidelines - when they started buying MJ.
But when they saw what was being wasted, most of those people started using the surplus in the pens.
And when Eli-Lilly put the prices up, everybody decided to buy higher dose pens and eke them out, to save money.
In a 15mg pen, the 0.8ml left over is 20mg of MJ. That's a whole 5mg pen. Who would throw away a whole 5mg pen?
