Once you put heat through the cart, its best to use it until empty.

I would say an unused cart, left in a dark, cool cupboard would keep for around two months before any separation/Discolouration would occur.

I would try to finish a used cart within two - four weeks of first use.

This would apply to carts made with distillate and terpenes, if made with pg / vg / peg, I would use within two weeks and store for no longer than 4 weeks.

I’ve still got a bit left of one of yours I bought months ago MJ no discolouration, the flavour disappears and potency isn’t as good but still good!

I got scared of vaping carts due to the negative hype, tried a few big name carts but they weren’t a patch on yours mate. I’ll be after a couple for my next holiday!

Mjs carts are absolutely banging. I haven't tried any others apart from some very basic pg/vg stuff a mate made but it was a bit duff.

I'd like to try some American brands but the risk of counterfeits is just to great, even from legit dispensaries. I've seen some 'Mario carts' which puzzles me as well as Nintendo are savage with their ips so how can they be legit/safe, I'll never know.

I trust mjs as they aren't trying to pass them off as anything other than their own 'brand' been using them for about a month or so and haven't expirienced any respiratory problems.

How do you make them mate?

Yeah the ham would be minging lol but I’m guessing cartridges might stay fresher quite a bit longer, I just wondered if anyone knew timelines at all! ?
