I bought a bottle about a month and a half ago, tried it for a few days, then decided to hold off on using it until now. The expiration date is 2/2010, but since I opened the bottle, did it lose its 'kick'?
No it's ok.
Do not go gentle into that good night...Rage! Rage! against the dying of the light!!
Absolutely not... I keep open bottles at home and the office so i dont have to drag supps around with me.
Wont hurt it at all
