Aged Trimix

[Nocturne]

Having good luck so far, although yesterday was a bit of a scare as I was hard for almost 4 hours before it went down (with a little help from my wife). Not convenient or safe. Going to have to adjust my dose down a bit I think, but weird because 23 units has been the sweet spot for a while now.
As it turns out, I drew the last needle I can draw from my working vial this morning. It’s empty.
But - I do have a vial that I got way back in August, and kept in the freezer until December or so. Only used it once or twice that month (that’s when I got a priapism with 35 units, which I will not do again!). Put that vial back in the freezer after that (in late December) and just took it out again a week or two ago.
Is it worth trying that vial again? It’s almost full and I did get soaked $500 for it (“Game Day” men’s center - beware, they overcharge!). I feel like it can’t hurt to try, but - could it? Can this stuff go bad?
For the record, the vial I just finished has been in my possession since… February. In the fridge. Been working fine all this time.
