The number of doping products seized by customs officials in France in 2012 were down on the previous year but still topped 300,000, a high-ranking customs official said Saturday.
The total number of products seized stood at 320,611 according to Jean-Pierre Garcia, director of the National Directorate of Intelligence and Customs Investigations (DNRED).
Garcia was speaking at the annual national conference on the fight and prevention of doping at the House of French Sport in Paris.
"It's a little bit less than 2011 when 327,000 doses were seized. I can say that in 2013 we've started very well because in February in Roissy (Charles De Gaule airport) we took 47kg of doping products," said Garcia.
"Our statistics will be better next year.
"I'm tempted to think that 300,000 doses is insignificant in relation to the mass of products in circulation."
He said the seizures included 73,182 doses of human growth hormone, all taken in one go at the airport.
More than half the products came from Thailand while significant amounts came from Greece and Slovakia.
Garcia highlighted that 10 of the most concerned countries were members of the European Union.
Doping in French sports has come under the spotlight over the last two weeks following an official senate hearing into the effectiveness of the fight against doping in sport.
