Well, here we shouldn't mix supplements with steroids. For eg. Creatine is said to be performance enhancing protein.

For eg. 2 cyclist with equal physical and sporting ability are taken into consideration. Their timing for x k.m. is same.

One of them is given supplement and the other cyclist is given just water. Either of the cyclist are not told what they were given. They are told to race for the same x k.m.

Would there be any difference in their timing? Or suppose the cyclist are told what they were given, the knowledge of supplement being taken plays in the mind of the athlete and the performance will increase.

Supplements i guess can help in improving the physical being like muscle mass, which in return could increase the power. But for performance to improve technique and natural talent has a larger role to play.

Anyone with answers would be really appreciated. 8o
