Testosterone Expiration?

Is it okay to go beyond the expiration date on your bottle of T?
My Dr. messed up by ordering me a bottle too soon and I just realized that what I am taking now will expire in the middle of December, but I have enough left to last through January.

It’s T Cyp in sesame oil.


No problem. The T molecule is very stable. Keep in its box to protect from light. The benzyl alcohol prevent bacterial growth.

KSman or anyone else -How long before you would get worried? I actually see my Doc soon and will ask him too. I’m figuring now its going to be the end of January before I run out, so almost 2 months past expiration.


I’ve read of guys keeping gear on hands for years before using it, you have nothing to worry about for a couple months.

Not an issue at all!
