Vials Question - Easy question

[some1else]

I have 2 vials that are good and I am using at the moment; however, I have another 2 vials that expired 06/2015.
They are all pharmaceutical grade, and I don't re-use needles.

Any how,
I was wondering if the 2 expired vials are okay to use once I finish those other two I am on, or is there a problem, are they too old, not usable anymore, infection problem, dangerous to body.. etc etc etc.


I keep them all locked in a dark black box in a dark place; they don't get any kind of humidity or sunlight, and they are stored in the house, aka, at room temperature.

They are good to go.

The only thing that can go bad is the oil. If the oil goes rancid, the color will change and it will smell bad. If the vial looks good and it smells normal, you're GTG.

If they were 10 years past due, I'd say maybe ditch them - and that's a maybe. 1-2 years is a no-brainer - they're 100% fine.
