Open vial degraded after 6 months?

So I'm going on 6 months of using a vial. Since I only inject ~80mg/week, it takes forever to get through a 10ml vial. On my most recent TT/FT test, my levels had quite a significant drop off without a change in dosage. There seems to be no general consensus on expiration on a vial once...

Is it safe to use injectables past their expiration date?

I have some injectable glutathione (preserved in benzyl alcohol) that I got prescribed last year. It’s from Empower Pharmacy, and unopened. Is it safe to use it if it says it was “expired” in December last year? Is that a real true “expiration” date?

Testosterone Expiration for opened vials

What's the opinion on Testosterone shelf life for opened vials.... ? I was thinking of giving Test Prop a try again and have 90-95% full vial from Empower that was opened about 13-14 months ago....(it was stored in dark, dry place, the color and consistency still looks like new). Any thoughts?

Bharat Serums Pre-mixed HCG

Looks like Bharat Serums offers it now under the brand name Hucog. Anyone used it? I imagine once you break the seal, it's got the same 30-day expiration clock. But apparently it's shelf stable before then?
