Conte, the founder and owner of the Bay Area Laboratory Cooperative (BALCO), helped a number of a leading athletes draw up programmes using banned performance-enhancing drugs, including sprinters Marion Jones, Tim Montgomery and Dwain Chambers, boxer Shane Mosley and baseball player Barry Bonds.

Conte was later sentenced to four months in prison for his role in the scandal.

He has since helped the World Anti-Doping Agency (WADA) go about catching drugs cheats, and under his new company Scientific Nutrition for Advanced Conditioning provides legal supplements for current athletes.

He has now been invited to address a number of US law enforcement officers by Travis Tygart, the chief executive of the United States Anti-Doping Agency (USADA).

The audience for his speech in Colorado Springs on November 5 will not feature Jeff Novitzky, the Internal Revenue Service (IRS) agent whose investigation uncovered Conte.

Conte is due to speak for 20 minutes and has told insidethegames that it will be "my prescription to fix anti-doping procedures.

"Travis wants my participation in a manner of my choosing.

"It's an honour for me to be invited to participate at the upcoming anti-doping conference.

"I've made serious mistakes in the past, so I greatly appreciate the opportunity to attempt to make a contribution."

But his message is set to be a controversial one.

"It will include a focus on increased out-of-competition testing and possible corruption in anti-doping agencies and in labs themselves," Conte told insidethegames.

"My advice to the attendees is that they might want to look at each other, and do a better job at gathering intelligence.

"The first tier is quality control.

"The second is quality assurance.

"There's a lot of money out there for those interested in not having a positive test.

"This isn't just about athletes or testing."
