Former Essendon player Mark McVeigh has slammed former teammate Kyle Reimers over allegations the club used supplements that contravened the rules of sport.

McVeigh, speaking to radio station SEN, defended the club and claimed that all injections were above board and the players knew what they were taking at all times.

“We knew that it was 100 per cent above board, and we trust and respect our coaches and doctors who knew about it,” McVeigh told SEN

“And that if anything was to come of it we’d be absolutely shocked and disgusted.”

The Bombers are under siege after requesting the AFL investigate unusual training methods during the 2012 premiership season.

McVeigh said everything he took was within WADA and AFL regulations, and that players had sought to make sure all rules were being followed.

"When we were told we would be taking certain supplements and having injections, the club and the players asked that we could have, not a waiver form... it was a consent form that the players asked for," McVeigh told SEN.

"We were going on a different program that we hadn't been on before. We'd never really gone into some of the supplements we were taking that we were going to take so we asked for a consent form that WADA and the AFL code would make sure it was ticked off and that it was within the regulations.

"We were comfortable with what we were taking."

He also claimed that the only off-site injections that were performed on him as a player were vitamin injections.

The former Bombers on-baller also put paid to claims the club had used the banned substance GRHP-6.

McVeigh also said he backed Essendon trio chairman David Evans, chief executive Ian Robson and coach James Hird 100 per cent.

However, he had less than kind words to say about former teammate Reimers, who he described as a "disgruntled player".

"Kyle Reimers has come out and said some things that are untrue," McVeigh said.

Essendon could face severe sanctions from the AFL if the club was found to be giving its players performance enhancing substances, while players could be banned for two years under WADA guidelines.
