Cat­a­lyst

The Weekend Australian - Review - - Television -

Thurs­day, 8pm, ABC1 This episode of the ABC’s flag­ship science pro­gram at­tempts to an­swer the ques­tion: ‘‘ Do we face a fu­ture where we will be in­creas­ingly brain dop­ing?’’ Only three out of five for gram­mar, but five out of five for this in­ves­ti­ga­tion into drugs in sport and life. First up, Maryanne Demasi looks into pep­tides, the main vil­lains in the re­cent Aus­tralian drugs in sport scan­dal. If your sport is about power and strength, then one of the most com­monly used pep­tides is hu­man growth hor­mone. Gym junkies would be well ad­vised to lis­ten up. ‘‘ Giv­ing the body more growth hor­mone than it needs does not make you stronger or more pow­er­ful,’’ says en­docri­nol­o­gist Ken Ho. Though mus­cles will look big­ger, most of that is ac­counted for by fluid re­ten­tion. The fo­cus of the episode is re­ally on how drug cheats and those who would de­tect them are in an end­less race against each other. But there’s plenty of sur­pris­ingly use­ful in­for­ma­tion about drug mis­use along the way.
