MJ expiry

[SquashPenguin]

I'm currently breastfeeding (pumping) but bringing this to a close at the end of November/ start of December. My BMI is currently 32, I put on a lot of weight during pregnancy and was overweight to begin with.

If I was to order MJ now, will it be ok to keep and start in a few weeks time? Or is the shelf life too short? I can't seem to find the answer online!

Yes, if you don't use it and keep it cold, I think the last pen I got said it had at 18 months shelf life before first use.

After you use it for the first time, you have to keep it under 30c ie. at UK room temp (though I think most people still store it in the fridge), and you're supposed to use the pen up within a month.

The shelf life has to be at least a month so that you are able to use it within the 30 days from first use as per the instructions. So some providers might provide a pen that has a short expiry date, because they expect you to use it pretty much straightaway. If they have old stock then they'll want to send that out first.

Having said that, the 2.5mg starting dose is likely to be the most frequently supplied so the least likely to have older pens in stock. I don't think I've seen anyone complain recently on here about getting a short dated 2.5mg pen. In all likelihood then expiry will be in 2025.

You could ask the pharmacy for the expiry date before you order, to check
