Creatine is probably the second most important supplement after whey protein. Creatine is a nitrogenous organic acid that helps supply energy to cells, primarily muscle cells, enabling them to contract harder for longer resulting in an increase in size and strength.
Proteins are the building blocks of muscle and as such are the most important supplements for any athlete. Whey protein is the most convenient and cost effective way to supplement your diet.
Whey Concentrate (Standard Whey Protein)
Whey Isolate (Pure Whey Protein - usually above 90%)
Whey Casein (Slow Absorption)
Hydrolysed Whey Protein (Fast Acting, Easily Absorbed)
