Overview
Is SiS Creatine worth adding to a cycling training program?
The SiS Creatine 400g Unflavored is pure creatine monohydrate: the most researched performance supplement in sports science, in a clean, unflavored powder format that mixes easily into water, juice, or a protein shake. Creatine works by increasing phosphocreatine stores in muscle, supporting the rapid regeneration of ATP during short, high-intensity efforts. For cyclists, that translates to improved sprint power, better recovery between hard intervals, and the ability to produce more force on repeated high-intensity efforts during training. Science in Sport delivers this at the clinically studied 3 to 5g per day dose with no added ingredients or flavoring.
The unflavored format is the most versatile: it adds no taste to whatever you mix it with, making it easy to stack with other supplements without flavor conflicts. Each 400g tub provides approximately 80 to 133 servings depending on dose. Creatine is most effective when taken consistently over time rather than acutely before a single session. A standard loading phase of 20g per day for 5 to 7 days followed by 3 to 5g per day maintenance is a common protocol, though a lower daily dose without a loading phase achieves the same end result over 3 to 4 weeks. Informed Sport certified, every batch tested against the WADA banned substances list.

FAQ
Good questions
Get to know Science in Sport

There's more to Science in Sport than this one product. Our Science in Sport page has the full Science in Sport lineup we carry and more about the brand.
Visit the Science in Sport page →How does creatine help cyclists?
Creatine increases the phosphocreatine stores in your muscles, which supports the rapid regeneration of ATP during maximal efforts lasting 1 to 10 seconds. This improves sprint power output, reduces fatigue during repeated sprints, and may support recovery between high-intensity intervals.
What is the recommended dose and protocol for creatine?
A common approach is a loading phase of 20g per day (split into 4 x 5g doses) for 5 to 7 days, followed by a maintenance dose of 3 to 5g per day. Alternatively, 3 to 5g per day without a loading phase achieves the same result over 3 to 4 weeks. Both approaches are equally effective long-term.
Is creatine legal for competitive cyclists?
Yes. Creatine monohydrate is the most studied supplement in sports science and is completely legal and permitted in competition. This product is Informed Sport certified, meaning every batch has been independently tested against the WADA banned substances list.
How do I take SiS Creatine?
Mix 3 to 5g (approximately one teaspoon) into water, juice, or a protein shake. The unflavored formula adds no taste. Take it at a consistent time each day. The timing relative to training matters less than daily consistency.
