What's on the labels (hero lines)

• Anabolic L-Glutamine: ingredients list L-glutamine only. Mix one 10g scoop with water daily and/or around training. The brand states the powder may contain traces of cereals containing gluten, nuts, peanuts, eggs, soy, milk and lupins — always check the pack you receive.
• Creatine Monohydrate: creatine monohydrate plus vitamin B6. Each 6g serving (2 scoops) lists 6g creatine monohydrate and 2.1mg vitamin B6 (150% NRV). Mix with about 300ml water or a soft drink. Made in Germany (brand materials).
• Caffeinated lines: Radical Riot lists about 300mg caffeine per serving, Psycho Pharma Edge of Insanity about 420mg, and Fatboy Killa 213mg. Those products are not suitable for under 18s, or for anyone who is pregnant or breastfeeding. Undisputed Pump Booster is labelled caffeine-free; Donald Pump contains gluten from roasted barley malt.

Creatine increases physical performance in successive bursts of short-term, high intensity exercise. The beneficial effect is obtained with a daily intake of 3g of creatine. Vitamin B6 contributes to normal energy-yielding metabolism and to a reduction of tiredness and fatigue. There are no authorised health claims in Great Britain for L-glutamine, beta-alanine or EAAs as such, so we list labelled composition rather than performance claims for those products.
