Why glass

Glass instead of a plastic tub.

Glass doesn't react with what's inside it, and it keeps out moisture and air (Pagnotta 2026). When the jar is empty, you can wash it and use it again.

We believe you deserve the highest quality for your body.

How are your products tested?

Each product is tested three times: once at the raw material location, once at the manufacturing facility, and another time as a finished product by an independent lab. We publish the independent lab's reports on our FAQ page.

How much creatine should I take?

Use our dosing calculator to find your daily amount.

When is the best time to take creatine?

Creatine is effective whenever you take it. Consistency is more important than exact timing.

Do I need to load creatine?

No, but it is faster. Loading (about 20 g a day, split into four 5 g doses, for 5 to 7 days) is the quickest way to fill your muscles' creatine stores. A smaller daily dose, such as 3 g a day, fills them more gradually over about 3 to 4 weeks. This applies to Creatine Monohydrate.

Why glass?

Glass doesn't react with what's inside it, and moisture and air can't get through it (Pagnotta 2026). Plastic is different: studies have found that chemicals can move from plastic packaging into food (Gerassimidou 2023), and plastic containers can release tiny bits of plastic into what they hold (Hussain 2023).

We believe you deserve the highest quality for your body.
