  1. Testosterone expiry dates?

    Sorry I'm a bit late to this, but my own experience may be of help. I re-analysed some samples of mine that had been collecting dust for more than 10 years (HPLC and Mass Spec) and found that they were still in top-notch order. The solution of one vial had darkened somewhat - probably oxidation of the oil - but the active constituent (DECA) was fine. The steroid skeleton is chemically fairly stable and as these are oily solutions the risk of oxidation and hydrolysis is small. However, I would suggest that they always be stored in the dark, as light can induce some photodegradation.
