Secret Stuff is a chalk cream. You rub a small amount on your hands - at first, it looks like nothing's there, but after a few seconds, the moisture will evaporate and you'll be left with a perfect layer of the highest purity Magnesium Carbonate we've ever made.

No mess. Longer lasting. The future of chalk.

    Don't just take our word for it...FrictionLabs Pro Dan Mirsky breaks it all down.

    Thanks to everything we've learned, we were able to give you:

    • 50% more chalk,
    • An even smoother texture, AND
    • More reliable packaging,
    • All while keeping the price the same!


    Why use Secret Stuff instead of other chalk options?

    Secret Stuff will naturally cleanse and disinfect your hands, killing bacteria and getting rid of gunk and grime that builds up over the course of your normal day and during activity. This unique cream will deliver chalk deep into the texture of your hands - as soon as you use it, you'll see how well it gets into every nook and cranny.

    Some people use Secret Stuff as a total chalk replacement. Others prefer to put it on at the beginning as a base layer, augmenting it with loose chalk or a chalk ball when they need to reapply. Some people like to use Secret Stuff as a mid-session refresher, helping cleanse and reset their hands when they start feeling worn down. Chemically, it doesn't matter - however you choose to use Secret Stuff, you can be sure you're getting the highest quality, cleanest, longest lasting chalk anywhere.

    How long will it last?

    A single 75mL bottle of Secret Stuff will last about 100 uses.

    Does Secret Stuff come in different blends/types/flavors/animals?

    Not this time - just super high purity Magnesium Carbonate engineered to help you crush.

    Frequently Asked Quesions

    Who is FrictionLabs?
    We are a group of athletes and scientists who realized that all the chalk out there was just awful - both for performance and for health. As we tested and developed our products, the reaction we got when people tried it was amazing, so we decided to start a business around the idea that Chalk Matters. We’re committed to doing everything we can to bring peak performance to every athlete who benefits from better grip.
    Isn’t all chalk the same?
    All chalk brands claim to be 100% Magnesium Carbonate. When you run the tests though, the truth is that they all have significant amounts of impurities, drying agents, heavy metals, and other fillers. We’re the first to admit that our chalk isn’t 100% pure; it would be extremely expensive and impractical to make. But our chalk is by far the purest out there, meaning it will last longer, dry your hands better, and keep your lungs and skin healthier than anything else you've been using.
    Why does it cost more?
    Our chalk goes through a proprietary process to remove unhealthy fillers common in other brands of chalk. Most climbers report re-chalking about half as often when using FrictionLabs since it lasts so much longer.
    Is FrictionLabs a specialty product meant only for elite athletes?
    Is organic food only for Olympians? This is the best, safest, and healthiest chalk on the market, making it the responsible choice for every person's health and performance. FrictionLabs chalk is the sensible standard, and thankfully more and more athletes of all experience levels are making the change every day.
