A NEWMAN Government MP says he would rather spend the rest of his life taking a banned performance-enhancing substance than drink fluoridated water.

Nudgee MP Jason Woodforth made the statement after The Courier-Mail raised the fact his bodybuilding supplement store sold a protein powder with an ingredient that is banned by sports anti-doping authorities and linked to heart, lung and liver damage.

BodiZone at Geebung stocks Body Ripped Superior Protein System, which contains growth factor 1 (IGF-1).

IGF-1, which is sold legally, is named in an Australian Crime Commission report as a substance athletes take to grow muscle and mask doping test results. The hormone is listed as an ingredient of Body Ripped by both the wholesaler and BodiZone on their websites, but is not mentioned on the product label.

Mr Woodforth agreed buyers should be told of any IGF-1 content on the label but he backed claims from the product's wholesaler that the concentration was small enough to have ``no metabolic effect''.

He claimed the health risks of peptides and hormones, which are at the centre of a national sports doping scandal, paled beside fluoride, a "toxic waste chemical''.

"If you gave me the choice of taking IGF-1 or fluoride for the rest of my life, I tell you which one I'd take right now,'' he said.

The Australian Sports Anti-Doping Authority warns that "non-therapeutic use'' of IGF-1, which is banned for athletes in and out of competition, can raise the risk of "cardiovascular disease, liver damage and hypoglycaemia''.

Queensland's chief health officer has accused Mr Woodforth of "scaremongering'' on fluoride.
