Expired cyp

Hey Guys and Girls. I have been out of the game for a couple years. I have some Upjohn cyp that has been expired for a year. It's a shame I know but I have had medical problems that have kept me from putting it to use. My question is, can I still use it? I have had several opinions and would like some facts.
By the way, nice changes to the board here. Thanks

Forgot about the research button. Answered my own question. And yes it's been in a cool dark place.

I would use it :)

Use it bro. It just might not be as strong..

Yeah give it a go
