I was gathering up all my testosterone and paraphernalia and noticed that the last vial I’d been using is 23 months past the expiration date. It’s a 10 ml of the 200 mg testosterone cypionate manufactured by Watson and filled by Walgreens. I know it still works because of my blood test results (and morning erections). I saw there were a few old posts asking about expired testosterone and thought I’d mention my experience. I also asked the pharmacist about expiration dates in general and she said they’ve gotten noticeably shorter since she graduated pharm school in 1991, probably out of fear of lawsuits. She said most drugs had exp dates of 4 or 5 years after manufacturing date and now it’s down to maybe 2 years. She also said she’s used meds after their exp date.
