How many scoops should I use?

Use one scoop for 30g of carbohydrates, two for 60g or three for 90g. Match the amount to your workout’s duration and intensity, and increase gradually according to your personal tolerance.

What does Formula 369 taste like?

Formula 369 has a light, neutral taste designed to remain easy to drink throughout long workouts. It avoids the heavy sweetness and strong flavors that can become difficult to tolerate over several hours.

Does Formula 369 contain caffeine?

No. Formula 369 is caffeine-free, giving you control over whether and when you add caffeine to your fueling strategy.

Does Formula 369 contain electrolytes?

Each scoop provides 200mg of sodium from Australian sea salt. If your training, climate or sweat rate requires additional electrolyte support, you can pair it with Formula 369 Electrolyte Booster.

Can I use it with CARB DOPE?

Yes. Use Formula 369 in your bottles for consistent liquid carbohydrates and CARB DOPE when you want a portable additional fuel source during longer sessions. Adjust your total intake to match your fueling plan and tolerance.

That depends on the number of scoops you use per workout. At one scoop per session, the 3 lb bag provides 45 sessions, the 5 lb bag provides 73 and the 10 lb bag provides 146. Using two or three scoops per session will reduce the number of sessions accordingly.

Great endurance drink! I’m a part time, totally unprofessional ultra distance cyclist and have used 369 on several long rides without any stomach discomfort. Fructose and Maltodextrin in a 1:1 mix works perfectly for me. I love the neutral taste and the affordable price. Thanks!

I love it. Keeps me fueled for my rides.

The 369 endurance fuel mix has been perfect in keeping my carbs up during my 2 to 4 hours cycling rides and the Lemonade flavor hydration mix pairs with it for an excellent flavor while helping me to avoid cramping and ready to fire when ready! No more needed gels or gummies.

The only thing better than 5lb Formula 369 is 10lb 369! Plain and simple, cost effective and performance-proven.
Love the convenience of the subscription, but miss the ability to buy a pair of sweet 369 socks every now and then 😜

No bonk!!

No bonk!! Really helped alleviate the bonking I was getting at mile 70. The flavor out of the box is sweet and creamy. It’s ok. However, I found it pairs very well with flavor packets. Shown in the pic with skittles orange and skittles green apple. Personally, I’m finding I prefer to use my own flavoring. I imagine a 5 or 10 lb bag of one flavor would get boring. My kids love it too! Elementary age girls. On hikes and activities they tend to get picky about food and snacks, but they’ll drink this no problem. Has prevented or stopped many low blood sugar tantrums! Overall, big fan! I started with the 5 lb bag. Just bought the 10 lb.

Great product! I have Crohn’s disease and have been using Formula 369 for a year now. I have had GI issues with several other fluid based products. I like how Formula 369 is simply, but effective! I enjoy the taste as well. Not overpowering and very easy to drink whether you’re using 2-4 scoops per hour. I highly recommend for endurance sport! My gravel ride yesterday was great using Formula 369 as my primary drink mix!

Great product!

Ran the Viper 200 using this and the caffeinated one later in the race and kept me hydrated and no cramps. First time getting through a race with no nausea. Started with one scoop early in the race and then added a second scoop later.

Formula 369 has been a game changer for me. Not just financially, but performance wise. Crushing new PRs on my Mtb. I just turned 60 and this stuff is like jet fuel for me. I don’t see myself going back to the other products. Thanks and keep up the good work!!

This stuff is absolute gold! It is easy on my G.I. track. Taste great and Does exactly what I needed to do. Highly recommend recommended.

Very happy with Formula 369! No weird colors or flavors. No overload of salt. Mixes easy and completely clear. A very mellow sweetness that won't bother your stomach at all. Provides everything I need on each ride AND it's affordable! I'm a fan👍

Great hydration product, and you can't beat the price.

I am loving Formula 369 after a few weeks of use! It mixes easier than other carb drink mixes. The mild, sweet flavor I find easier to drink than others with lots of flavoring added, especially when you're going full gas! I can't wait to try the caffeinated version as well.

Love this stuff. Easy on the gut. I can feel the difference in fueling during long rides compared to other drink mixes.

Wish I had found this a long time ago.

Did 51 miles on gravel in 90 degree temps in Oklahoma with Formula 369 and was very impressed. Flavor is lightly sweet. I used 3 scoops in each of two large bottles and that was perfect. Skratch tastes great but the cost compared to this makes me laugh. SIS powder is loaded with aspartame, no thanks! F369 is great and the price is incredible.

As you can see I'm almost finished with my first 5lb bag. So glad I gave this a shot when it showed up on my social media feed. It's now my primary drink mix. Taste good, just a simple sweet flavor, even when it's not so cool anymore. Also the sustained energy and feeling like you're not going to bonk is real.

I Love this stuff! easy to go 10+ hours w/out needing food. so good for endurance. so much easier on my gut than anything else I've tried. 24 hr races are a gogo!

Currently training for a 500 mile ultra. It has been tough to dial in the nutrition, but F369 has made is easier. I have built up my tolerance to 90 carbs/bottle/hour and will be using this as my primary carb fuel source.

Gathering winter fu u el like I was King Wenceslas on a bike

Everyone can spin the peddles quick for a bit. But stamina only goes so far before the tank runs out. So you need to fuel. I used to but the SiS Beta fuel for $$$$ but never really liked it. Too sticky and made the water a bit claggy. This is my first bag of 369z I liked the look of the lad selling it, his background story his tips and tricks on his instagram page too. So I am giving it a try. First. It blends with the water really well. A little soupy but still refreshing and nowhere near as claggy as the other stuff. It’s doing a good job helping go longer miles and the last days of 2023 I hit my targets with a bunch of big rides day after day after day. So. If you’re reading this you are obviously doing your work and research and want this stuff to be good. I think it is, I am sticking with it and pretty sure it’s going to help fuel my goals of 2024. Ride on brothers and sisters

Great fuel for rides big and small! You won’t find a better deal. I like to put a splash of lemon juice in mine for a nice subtle fresh flavor. Would recommend for anyone looking to experience the benefits of fueling appropriately without breaking the bank.

Hands down the easiest and best mixing carb powders I have used. No overwhelming artificial flavoring just the right amount of sweetness to change up from drinking just water.

I've done 3 rides using this product (46mi/2500ft, 70mi/3500ft, 80mi/6000ft) and didn't feel hungry at the end of my rides! And it increased my 20min FTP to 318w (155lbs).

It’s simple carbohydrates and electrolytes and affordable. You can destroy your body by pushing hard but not destroy your bank
