About Us

After trying out many shakers – at the gym, on the go, at the office – one thing has become clear to me: many models fail where you really need them most. They leak, they're loud, they're slow.

With GainShaker you get a product that solves these problems: 100% leak-proof , quiet in operation , robustly built and ready for everyday use – not just for show.

Our values

• Quality & Function : Each shaker is carefully selected, tested and designed to bring you real added value.

• Honesty & transparency : No exaggerated promises. When we say "tight" and "quiet," we mean it.

• Customer-focused & reliable : I am personally available for immediate contact, ship quickly, and am ready to answer your questions – so that you are satisfied.

My promise to you

• Shipping is prompt – so you don't have to wait long.

• If something isn't right: Just let me know. I'll take care of finding a solution.

• And of course: You get a product you can rely on – in the studio, during your workout, or on the go.

Thanks for joining GainShaker. Have fun mixing – and achieving new personal bests!

Sporty greetings,

How is it ensured that the shaker remains airtight?

"Our shakers are equipped with two hard rubber seals. One in the lid and a solid rubber seal in the closure at the mouthpiece." (see image 3)

Are the shakers washable?

"Yes, our battery shakers are washable and 100% leak-proof – both inside and out."

Is the shaker quiet enough for everyday use (e.g., in the gym)?

"Yes, our shakers are virtually silent with the lid closed."

Does it have a self-cleaning function?

"Yes, there is a self-cleaning function."

Simply add cold or hot water + soap (dish soap) to the shaker, close the lid, press the button, shake, and then rinse with clean water.

How long does the battery last, how many shakes?

"Our long-term tests showed an average battery life of 50 minutes. This gave us approximately 55 to 70 shakes per charge."
