GU EnergyLabs Original Sports Nutrition Gel - Jet Blackberry

Q: Which flavors have caffiene and which do not?

GU energy gel comes in both caffeinated and non-caffeinated flavors. Strawberry Banana and Lemon Lime (& peanut butter) do not have any caffeine in them. Orange, Vanilla, Chocolate, Triberry and Plain all have 20mg of caffeine per packet. GU's Espresso Love flavor has 40mg of caffeine. Caffeine consumption during exercise improves performance in several ways: it sharpens focus and perks you up; but more importantly, it helps the body produce more power, reduce the pain of hard efforts, and may even tap fat for fuel during exercise. All of this prolongs your ability to exercise at a high intensity. We use just enough caffeine to jump start this benefit and no more. (From the GU Energy website). There might be other flavors out there but just check the website to be sure.

Q: How long do these stay good? When do they expire? I don't see an expiration date on the outside of my box...

When checking our stock for an expiration date we find they do not list an expiration date on the box. We have find they say these are best before 11/2015. Quite a few articles we have found say that these are still good past the best before date, however we would recommend consuming these before that date to be safe.
