ABOUT THIS PRODUCT

 

In development, a beta test is the second phase of testing in which a sampling of the intended audience tests a product or service. Beta Fuel has been in elite testing since summer 2017 and we will continue to gather elite insight and complete performance trials throughout 2018.

How does Beta Fuel work? A rate limiting factor of exogenous carbohydrate utilisation during exercise is the transportation of the nutrients across the intestinal wall. Once the sodium-dependent transporter, used to transport maltodextrin, is saturated at 60g per hour, additional carbohydrate in the form of fructose can be absorbed through another transporter, GLUT5.

Fuelling long endurance events (greater than 2.5 hours) requires 60-90 g of carbohydrate per hour. Beta Fuel has been developed to deliver these high levels of carbohydrate with minimal risk of GI issues.Why 2:1 now for Science in Sport?2:1 ratio sports drinks aren't new; however, historically they're delivered in hypertonic solutions meaning a high risk of stomach upsets which is why we've avoided as a brand. Now, following a development cycle alongside Team Sky, 2018 Giro D'Italia Winners,

Beta Fuel is a breakthrough technology delivering the optimal dosage of carbohydrate whilst maintaining an isotonic solution.What's the recommended usage for Beta Fuel?Mix one serving of Beta Fuel with 500ml fluid and drink little & often during exercise to meet fuelling requirements. No complicated directions, our drink isn't limited by a need to use a specific type of water like other niche brands, simply mix & go.

Very nice shirts but unusually long sleeves
Size: Large, Color: Light Green
PJ PAUL JONES Mens Dress Shirts Wrinkle Free Stretch Button Down Shirt. I bought white, coffee, grey, autumn green and apricot. Colors are true to the ads. I'm 6' , 170 lbs. I bought these in Large. They fit very well in shoulders, chest, and my big belly. As many reviews have stated, the sleeves are unusually long - coming down past my palms to my fingers. I would give them a 4 rating for that but I bought them with the intention of making them short sleeve. The white shirt is just too nice to change so I'll reserve that for weddings and funerals. The apricot is very nice but I just wouldn't wear that color as a casual shirt but it does go with my brown blaser so I'll keep it for rare occasions. I washed them in warm and put them thru warm dryer and didn't notice any shrinkage which I wouldn't expect with polyester. Very good shirts at very good price.

A Solid Buy
Size: XX-Large, Color: Black
Purchased this shirt to wear to a concert. I love the material because it's stretchy and flexible unlike the traditional cotton. It's mainly wrinkle free but I ran a warm iron to get out the creases from being folded. I wore this with gray pants and it made my outfit feel put together. The sleeves are very easy to roll up and won't come undone. A very nice shirt to add to your clothing collection.

Good looking shirt that runs a bit big in sizing.
Size: X-Large, Color: Green Gray
Nice looking shirt for dress up or casual wearing. Feels like silk, pretty wrinkle free. Lots of colors to chose from at a good price. Runs a bit big in size. I found the sleeves very long for me. But I like the casual look, feel and coolness in the heat of summer for a long sleeve shirt.
