I have a vial of testosterone that expired on 10/06. Needless to say, the degradation is gradual, so if it was safe to use during 8/06 and 9/06, it'll be safe on 11/06 and 12/06. Does anyone know how they set these dates? Is 10/06 the date that, say, half of the potency would be gone? It was compounded testosterone and the expiration date was very, very close to when I purchased the medication. Very strange. It's the "brand" that Crisler gets from Signature Pharmacies. I want to take testosteone again, and I can't afford a doctor's visit or another vial. Shall I give this a shot?
