While many of the claims are based on scientifically based physiological or biochemical processes, their use in bodybuilding parlance is often heavily colored by bodybuilding lore and industry marketing and as such may deviate considerably from traditional scientific usages of the terms. In addition, ingredients listed have been found at times to be different from the contents.
In , Consumer Reports reported unsafe levels of arsenic, cadmium, lead and mercury in several of the protein powders that were tested.

Prohormones are precursors to hormones and are most typically sold to bodybuilders as a precursor to the natural hormone testosterone. This conversion requires naturally occurring enzymes in the body. Side effects are not uncommon, as prohormones can also convert further into DHT and estrogen.

To date most prohormone products have not been thoroughly studied, and the health effects of prolonged use are unknown.

A number of scientific studies have shown that creatine can improve strength,  energy,  muscle mass, and recovery times. In addition, recent studies have also shown that creatine improves brain function. Creatine increases what is known as cell volumization by drawing water into muscle cells, making them larger.
Creatine is sold in a variety of forms, including creatine monohydrate and creatine ethyl ester , amongst others. Though all types of creatine are sold for the same purposes, there are subtle differences between them, such as price and necessary dosage.
