Supplements buying guide

Compare the price per serving

Protein powder and creatine are sold in many tub sizes, so compare the price per serving or per kilogram rather than the tub price. Larger tubs are usually cheaper per serving.

Check the dates

Discounted supplement stock is sometimes close to its best-before date. Listings on this site exclude short-dated stock where the seller says so, but it is worth checking the date in the description.

What the label tells you

Look for the protein content per serving and the ingredient list. Products tested under schemes such as Informed Sport are worth favouring if you compete in tested sport.
