Creatine is not a steroid, it’s a compound found in foods and is great for your health.
It increases muscle strength and power, enhances high-intensity exercise performance, and supports muscle recovery and growth. It also improves anaerobic capacity, boosts brain function and cognitive performance, and increases energy availability during workouts. Additionally, creatine aids hydration by pulling water into muscle cells and may help reduce muscle damage during intense exercise.
Typical dose? 5 mg creatine monohydrate. The brand doesn’t matter, it’s cheap and easy to find.
Side effects? Digestive issues in the short term, water weight retention. Anecdotally some people claim it causes hair loss, though research shows it does not.
