The Mystery of Pre-Workout Clumps

Why Do They Happen and How to Prevent Them

You're ready to hit the gym, motivated and pumped up to get your workout on. As you reach for your trusty pre-workout supplement, excitement turns into annoyance when you notice unsightly clumps inside the container. If you've experienced this frustrating situation, fear not, as you're not alone.

Many fitness enthusiasts encounter the phenomenon of pre-workout clumps. In this blog post, we will delve into the reasons behind this common issue and explore effective ways to prevent those pesky clumps from spoiling your workout routine.

Moisture and Humidity

One of the primary culprits behind pre-workout clumps is moisture and humidity. Pre-workout supplements typically contain hygroscopic ingredients (like L-Arginine and Citrulline in our GoPrimal Humping&Pumping), which means they attract and absorb moisture from the air. When exposed to humidity, these ingredients tend to bind together, leading to the formation of clumps.

Do not remove the moisture-absorbing packets (desiccants) in the supplement containers to mitigate this issue.

    Prevention: To prevent clumping due to moisture, store your pre-workout in a cool, dry place, away from direct sunlight and moisture-prone areas like the kitchen or bathroom. Consider using airtight containers or resealable bags to further protect the powder from humidity.

    Long Storage Period

    Over time, especially if you don't use your pre-workout frequently, the powder may sit in the container for extended periods. This extended storage can lead to moisture absorption and clumping.

      Prevention: If you don't use your pre-workout regularly, consider purchasing smaller containers or portioning out the supplement into single-serving sizes. This will minimize the exposure to air and moisture, reducing the risk of clumping.

      Improper Storage

      How and where you store your pre-workout can make a difference. If the container is left open for an extended period, the powder is more likely to be exposed to air and moisture, leading to clumps.

        Prevention: Always make sure to tightly seal the container after each use. If you notice clumps, break them apart gently using a clean, dry utensil. Additionally, consider transferring the pre-workout to a new container with a better sealing mechanism. Pro-tip: a simple food blender can turn clumps into fine powder again!


        While pre-workout clumps can be a frustrating occurrence, understanding the reasons behind them empowers you to prevent and manage the issue effectively. By storing your pre-workout properly and being mindful of environmental factors, you can maintain the integrity of your pre-workout and ensure it remains lump-free, allowing you to focus on maximizing your workouts and achieving your fitness goals. So, say goodbye to clumps and hello to uninterrupted workout sessions!
