I have come into an almost full bottle of Winstrol (Stan QV). Its a 50 ml bottle with about 5 ml missing. Meaning it was previously used and the rubber breached. I am unfamiliar with Winnie so I have a few questions about this particular bottle. First, how long does winnie last (the expiration date on the label is torn off? Is it supposed to be milky looking (I read this is what it is supposed to look like)?
