In the assorted pack are they caffeinated? looking for only non caffeinated options.

now they have a new assorted pack, with no caffeine. Alas, only 4 tastes in it, and they are many great ones.

Purpose of amino acids in GU?

Hi, great question and thanks for asking! We have BCAA (branch chain amino acids) in just about all GU products. BCAA's refer to the three essential amino acids — leucine, valine, isoleucine. BCAA’s are metabolized in the muscle and help by preventing the breakdown of muscle tissue during and after exercise. Leucine, the most important amino acid, is critical in initiating the protein synthesis, the process through which your muscles rebuild and get stronger. So, these amino acids will help both during and after exercise! For more information and details, please see our website: www.guenergy.com Thanks! - Brian, GU Energy Labs

Can anyone report on the shipping time for the Variety Pack? Estimated delivery date is the 7th. Can't believe it takes that long...

Hi David! The ship time would depend on where you live. We are located in Upstate New York so our ship times would vary based on your distance from the upper east coast. Although it usually doesn't, shipping to the west coast could very well take a full week.

Are the "assorted flavors" the ones that are pictured? I ordered a box before from Amazon and it was different.

I have purchased the assorted flavors box three times, and each time it has been different. I have never received all the flavors pictured. I have always gotten some vanilla, chocolate, salted caramel, espresso, mandarin orange, strawberry banana. The number of each will vary, and the other flavors I get have also varied (e.g. sometimes I get blackberry or tri-berry, other times I don't). I have also gotten flavors that are not shown at all there. I have found that I do have a preference for some flavors, so now I order the boxes of the flavors I like.

Great Boost for Long Runs and Workouts!

I’ve been using GU Energy Packets for my long runs and intense workouts, and they’ve been a game-changer for maintaining my energy levels! The flavors are delicious (I’m a fan of the strawberry banana), and they’re easy to consume during my runs without slowing me down. The texture is smooth, and they’re easy to squeeze directly into my mouth for a quick energy boost.I’ve noticed a big difference in my endurance since incorporating these into my routine. They help to keep me fueled throughout the session without causing any stomach issues. I also appreciate the added electrolytes to keep me hydrated.If you’re looking for a reliable and tasty source of energy for your workouts or endurance activities, I highly recommend the GU Energy Packets! They’ve been a key part of my training and performance.

Good for the Price and Variety

Good to have a variety of flavors to select from. The Strawberry Banana is the best so far. The Lemon Sublime is ok and will take getting used to it. No after taste and not gritty. Haven't tried the other flavors yet. Easy to open. Not runny. So far happy with the purchase.

Favorite kind

Love these ones, great variety. I usually take them about 30-45 in to a run. Used them on my marathon and they definitely helped

Good but not the flavors I ordered

Similar as other reviews, I didn’t receive the flavors I ordered but I’m okay with it. I’d rather try a variety to see what I like. I ordered 6 of each: Strawberry Banana, Lemon Sublime, Birthday Cake, Campfire S’mores. I didn’t receive 6 of each but got some replacements with Raspberry Lemonade. Still got 24. Excited to try the flavors!

My favorite race fuel.

I am a long distance runner and I have found these to be the most reliable gels. I don’t want a bunch of caffeine and I don’t want flavors that are sickly sweet. These work well and have never upset my stomach. Very easy to open and stick the wrapper back in my pocket. I also don’t feel like they’re that sticky as some gels can be.
