A Word of Warn­ing

Dr An­drew Jowett, from Mel­bourne's Olympic Park Sports Medicine Cen­tre, be­lieves oth­er­wise. “En­doge­nous or nat­u­ral pep­tides play an im­por­tant role in nor­mal hu­man phys­i­ol­ogy but the use of ex­ter­nally man­u­fac­tured pep­tides is not fully un­der­stood in the re­search, which is in­suf­fi­cient to sup­port their wide­spread safe use out­side ap­pro­pri­ate re­search tri­als. The main con­cern with sub­stances that stim­u­late cell growth is they may stim­u­late ab­nor­mal or ex­ces­sive growth in cells such as can­cers, trig­ger­ing the de­vel­op­ment, growth and spread of tu­mours in the body.” Adds Dr Jowett: “The pur­ported ben­e­fits of pep­tides don’t take into ac­count the com­plex in­di­vid­ual mi­lieu of the hu­man phys­i­ol­ogy where a num­ber of hor­mones and growth fac­tors act in a co­or­di­nated man­ner. Of­ten when the claims sound too good to be true – it’s be­cause they are.”
