How It Works

Inside skeletal muscle tissue, creatine binds with high-energy phosphate groups to form phosphocreatine. This molecule serves as the immediate donor required to rapidly resynthesise adenosine triphosphate (ATP)—the body’s primary chemical fuel for short, explosive muscular contractions such as sprinting, jumping, and heavy lifting.

During intense exercise bouts, intramuscular ATP stores deplete within seconds. By supplementing daily with SiS Creatine, you saturate your phosphocreatine stores, enabling faster ATP regeneration between successive sets and sprint efforts. This delays muscular fatigue, increases total training workload, and supports intracellular cellular hydration, creating an ideal environment for muscle repair and strength development.

Recommended Use

• Standard Daily Use: Mix 1 level scoop (approx. 5g) with 200–250ml of cold water, juice, or your favourite post-workout protein shake. Consume once daily.

• Optional Loading Phase: Take 1 scoop (5g) 4 times daily for 5–7 days to rapidly saturate muscle stores, followed by 1 scoop daily for maintenance.

• Hydration Tip: Maintain adequate daily hydration by drinking at least 2 to 3 litres of water daily while supplementing with creatine.
