Dr Felipe Contepomi is the face of World Rugby's new programme pointing out the inherent dangers of taking supplements in order to make gains in size and power.
The former Leinster stalwart is at the forefront of an Anti-Doping campaign entitled 'Take Supplements; Take a Risk.'
"Do I need to take supplements? That is the first and biggest question," said Contepomi.
"Our metabolic necessities can be fulfilled by good nutrition, by good training and good rest."
This all happened on 'Keep Rugby Clean Day' as the Irish U20s were preparing to face down one of the most testing physical examinations in the game from The Baby Blacks.
