Yes, it seems you have 10 vials of 40mg each. That’s a significant amount of GLP unless you’re using a high dose of around 10-12mg weekly. There isn’t a lot of reliable data on how quickly GLP meds degrade after being mixed (with the bacteriostatic water you likely got with your peptide), but I’ve heard three weeks is a reasonable estimate. Some say they can last 2-3 months if refrigerated after mixing. I usually try to finish my vials within 2-3 weeks, so I typically buy 10 or 20mg vials. However, when I’ve bought 30mg vials and used them at lower doses, they’ve lasted 2-3 months without a noticeable drop in effectiveness. Keep your unconstituted peptides in the freezer for a longer shelf life, and don’t reconstitute more than one vial at once! At that strength, you could mix with 4ml, so a unit (.1ml) would be 4mg, or if you're dosing less,.05ml would be 2mg. If you're aiming for a microdose of around 1mg, you might want to mix with more, but I think your vials are likely the smaller 3ml ones, so you might not fit 4ml in there. Good luck!
