Quick question

[John S]

i started a cycle of winnie and deca , well after some reading and help from you people i realized that i needed more time to learn about using, my question is can it go bad from not being used after its opened/injected into?

thanks JS

I am not positive but I would still use the same experation date, even if I used it before. I am glad you are smart enough to realize that it wasnt time to start.

not if you don't let it sit for years
