Not always the case. My 1.5 year old test went rancid. QSC confirmed to toss it. Oil may go bad long before the potency of the anabolics do.Kept out of light, generally, if made properly, at least 5 years, Many reports of Test much older than that still good, and I believe tests showing minimal loss of effectiveness. A few percent at most.
But of course with those shitty QSC stoppers who knows. Might be a good idea to transfer into new vials using a filter syringe for long term storage.
