The package says expire by June 2023. However, these little guys are not drinkable quality.
I am unsure if it was a sreoage situation or what but thw ones I got taste like sugar free cough syrup powder into weak coffee.
I do recommend the Celsius drink line itself. It good for folks who don’t like super sweet flavors. It doesnt give large boost of energy though. And this is more of an after work energy drink to me.
