Can you premix it hours before use or will it go bad?

Yes, you can premix Tailwind hours before use (and even store it in the refrigerator for around 7 days). If you wanted to mix it up prior to an event, you can do that as well several hours beforehand.

Is there a caffeine free option?

Yep. All the Tailwind I purchased has been caffeine free. The caffeinated version is indicated below the flavor on the front of the package.

What is it solubility?How many grams of it can be dissolved per 100 ml of water at about 68 degrees Fahrenheit？

Hi Mask, Thanks for your question, it sounds like a question about making concentrates. Here’s a link to our website, and a blog post about making a concentrate: https://tailwindnutrition.blog/2019/04/08/tailwind-concentrate/ Basically it says “it’s OK to make a concentrate, but make sure you drink enough water,” and doesn’t give a specific recipe. One of the reasons for this is that the recipes will be quite different for mixtures that are shaken (during a run or ride), and mixtures that stand and are allowed to settle. It turns out that 8 hours of Tailwind, 3 scoops per hour, or 24 scoops, will fit in a 750 ml bike bottle (I used level scoops), but only after it’s mixed with water. The volume of Tailwind powder mixed in water is a lot less than the sum of the volume of Tailwind powder and the volume of water added to it. Hot water works better. Here’s a method for 8 hours of Tailwind concentrate in a 750 ml bike bottle: 1) Add 6 hours worth (18 level scoops) of Tailwind to a 750 ml water bottle 2) Add 200 ml of hot water (electric kettle works well here), and shake well. Notice the volume goes way down 3) Add 2 more hours worth (6 level scoops) of Tailwind 4) Add another 100 ml of hot water, and shake well 5) Notice there’s some room to spare … add another 80-90 ml hot water, whatever fits However, I might suggest a less concentrated formula, because in order to use this concentrate you’re going to need a second water bottle. So why not start with that second water bottle already mixed up? Some options for 8 hours on the bike: 1) Two water bottles: One bottle with one hour’s worth (3 scoops Tailwind, 720 ml water), one concentrate bottle with 7 more hours 2) Three water bottles: Two bottles with one hour’s worth (3 scoops Tailwind, 720 ml water), and one concentrate bottle with 6 more hours 3) Four water bottles: Three with Tailwind mixed up, on concentrate bottle with 5 more hours Remember that if you eat other food (sandwich, gels, bars, spaghetti carbonara, whatever) you should drink just water with it, as Tailwind and food together can be a little much for you stomach. I hope that helps! Regards, Art Art Zemach, M.D. Director of Research and Development Tailwind Nutrition, Inc. 1099 Main Avenue, Suite 210 Durango, CO 81301 email: art@tailwindnutrition.com
