How many clicks in MJ pen?

It’s the old one with the golden dose still. I know 240 clicks is 4 x full dose but curious how many ‘extra’ clicks they have for priming.

Well, it has to be at least 8 as the instructions say to prime by turning to the second line for each of the 4 doses, so 2 x 4. Then, repeating if necessary, so that would be 16 clicks, and again if you have to change needles after that, so 24 maybe?

I've just logged clicks and doses for a whole pen, imcl remaining fluid and it worked out to be 315 clicks or 52.5mg in my 10mg pen! I used my pen for 2 months, 9 doses. The remaining fluid is always more than a full dose in the old pens. FYI I don't prime, but a few drops would have been lost when the needle goes on. Also the last dose I removed with a syringe.

I click count from a 5mg pen. I’ve got between 308 and 328 clicks/units.

11 doses is the most I have got from one - only on 2.5mg and now in maintenance.

In my experience, about 256 actual clicks until the pen locks up and you have to break the mechanism or use a syringe for the remaining medication.

Ignore the bot…. It’s very straightforward to work out how much medication each click is. 1 click is 0.01ml of medication. No guesswork needed, just some very simple maths.
