Testosterone Expiration Date Question

[Jinzang]

I am using a vial of Testosterone Cypionate, 200 mg/ml in grapeseed oil. It has an six month expiration date and I received it two months after it was compounded. By my calculation there will still be 4 or 5 doses in the vial by the time I reach the expiration date. How hard and fast is the expiration date and what problems will there be if I continue using the vial past that date?

That is a "use by" date, not a "this product no longer works beyond this date" so you are fine.

I agree with ERO, I wouldn't worry about going past the expiration date. But I would keep it out of the sun.

I read an article recently where a company did potency tests on several medications some as far back from the 1940's. It showed all the drugs basically kept their potency several years past the expiration dates. I think the drug tested from the 40's still showed like 85% potency. Not sure if injectable drugs were included
