I was wondering if anyone knew if there was an expiration date on the Carb Boom gel product. I used one this weekend that I had from last year and ended up not feeling right afterwards. I've kept them stored properly. It might have been a case of a 24 hr flu bug but I'm kind of nervous about using the remaining 10 packages I've got. Does anyone have any experience here? I did drink a lot of water as I used the product.

Thanks for the help.

:confused:

Explain what you mean by not feeling right. I find Carb Boom products to be nasty and not sit well on my stomach, so it could just be they don't agree with you. Have you ever used them before?

I guess you're right I didn't explain myself. AFter I returned home I felt a little stomach ache. I ate breakfast and it didn't go away. Later I ate lunch and it was still hurting. Around 4:00 pm I had to lie down because my stomach was burning. I ended up throwing up later that night (once) and felt a lot better. The next day I still felt like I was getting over the flu. I did drink a lot of water before and after I ate the gu shot. I've used them before with no ill side effects. I'm not sure if it was the case of the flu or a bad carb boom pack. I've had these since the end of last summer.

I don't know if I should throw the rest of them away or not.

I have about 4 cases of carb-boom from last summer, I use one or two on every ride, and have yet to have any problems. I prefer carb-boom over GU any day...

i think they are expensive? so i hate to say this, but when in doubt throw it out :(.
another option, check if they have a website and email them the question, you never know thats the kind of thing where the company might send you a coupon for some free bees just to avoid the risk of you getin sick from there product.

I doubt that they had spoiled. Most of these products are very high in sugars. What causes things to spoil is microbial action. Bacteria can not attack concentrated sugars like honey because they suck water out of them.

Years back, I worked in a biology lab. And like all labs, it had some strange things lying around. This lab had a bunch of tin cans of "light boat rations" from WWII. At the time these things were 40+ years old. They had hard candy in them - basically pieces of fused sugar. They used to be fruit flavored and colored but had all turned a deep amber color. One of our more deranged postdocs opened the can and ate one. He pronounced it quite edible. And what with all of us being cheap, we snacked on the silly things for the rest of the year and no one suffered any noticeable ill effects.

I would think that maybe you are not used to eating this product now and that is why it bothered you. The thing is if it bothered you, you will remember that and avoid it in the future (whether the product was at fault or not).
