I forgot this, but during my last cycle I extended it by a few weeks. I ended up opening a bottle of test, but only doing a few pins out of it.

I hadn't thought about it, but I wrapped it in plastic and kept it with my unopened viles. That was like march.

Would that vile'S test still be safe to use?
