The US-based wellbeing company 10X Health Systems are at the centre of Paul Pogba’s failed doping test last year, Mail Sport can reveal.

High profile ‘health-guru’ Gary Brecka and 10X doctor Carrie Carda also find themselves involved in the storm that leaves Pogba fighting for his career.

The 30-year-old tested positive for DHEA, a banned substance that boosts testosterone, after featuring for Juventus in their opening game of the season against Udinese on August 20.

Pogba has subsequently been banned for four years, which given his age places doubt on whether he will ever play professional football again.

The former Manchester United midfielder is currently preparing for his appeal to be heard by the Court of Arbitration for Sport.

And Mail Sport can reveal American clinic 10X Health Systems are alleged to have supplied Pogba will the the pills he believes were responsible for his failed drugs test in September, with the firm cited in the midfielder’s appeal submissions.

It is understood there is photographic evidence of 10X Health Systems name featuring on the label of at least one of pill bottles received by Pogba.

Pogba details that following a consultation with Brecka, who is listed as co-founder and chief human biologist for 10X Health Systems, he was recommended to take a course of tablets after tests flagged certain deficiencies in his body.

Brecka is widely recognised as one of the most recognised figures in the health industry.

He has been photographed with a number of the biggest stars in sport on the planet - Cristiano Ronaldo and David Beckham among those snapped with Brecka, who has been dubbed the ‘celebrity health guru’.

Brecka is also understood to have a history with NFL and UFC stars and reported to have a number of clients in the public eye including P Diddy and Kendall Jenner.

In his submissions, Pogba also claims that Dr Carda, listed as a medical doctor on the 10X Health Systems website, administered the pills.

It is understood at least one of the bottles of pills received by Pogba reads ‘Prescribed by Carrie Carda’ on the label.

A passage on the 10X Health System reads: ‘We’re on a mission to 10X people’s wellness throughout the world by enhancing human performance.

‘And here’s the truth… modern medicine isn’t a patient-centric practice. We want to bring you on a wellness journey that’s going to change your life for the better and propel you to the next level.’

They have four health centres across the US, three of which are in Florida and the other in Beverly Hills, California.

Representatives for 10X Health Systems and Pogba both declined to comment.
