The Evolution
Pro Athlete Supplementation was formed as a result of a successful winning partnership between Jon Williams and Darren Campbell. Jon was responsible for Darren’s nutrition during the last 10 years of his career where he amassed his gold and silver medals. At the time when Darren was close to retirement Jon suggested that they form a company to develop the most effective sports nutrition products for professional athletes, football and rugby players. Hence PAS was formed. Working within professional sport over the last ten years Jon always wanted a better option to give athletes, explains Darren. When you are there with the athlete and the drug testers turn up you want to know 100% that the products they are taking are free from contamination. At one point everyone just avoided products that were on the banned list, no one thought products that we could buy off the shelf could be a problem, I was lucky Jon looked after me to ensure we worked with good companies, however Jon said that the only way we can fully guarantee is if we make the products ourselves. Today we source the raw materials, we blend the product in our clean room and we test every batch with HFL. Now we can have total confidence in saying our product is safe.

Darren’s aim following retirement was to maintain involvement in professional sport, to be able to help other athletes achieve their goals, the sprint training consultancy that he provides to football and rugby players (Andy Johnson and Mark Cueto to name just two) and his role with PAS fulfils this ambition.
Darren’s main priority was to ensure the products were safe for all drug tested athletes, since day one all products have been batch screened at HFL to ensure they contain no banned substances. We have been actively involved with HFL and the development of the Informed Sport testing protocol and are fully committed to its widespread application in professional sport.
