How long can u use Winny past the label date and it still be effective?

[tbro]

I was just told at my gym that you can use it up to 18 months past the date?

Well it's not a set date exactly. For example if the expiration date is June 1st. That does not mean that exactly on June 1st it will lose half its potency. It's just "an average" used by Pharm. companies to give pharmacists a rough idea of when they should start being more attentive.
