Case report: Possession of… • Testosterone-enantate, Testosteronepropionate, Testosteronecypionate, Testosteroneisocaproate, Testosteronephenylpropionate, Testosteronedecanoate • Trenboloneacetate, Trenbolone-enantate, Trenbolonehexahydrobenzoate • Metenolone-enantate, • Nandrolonedecanoate, • Boldenoneundecylenate, • Oxandrolone, • Metandienone, • Oxymetholone, • Fluoxymesterone, • Methyltestosterone • Stanozolol • Tamoxifen • Clenbuterol • Somatropin, GH-Fragment 176-191, mod- GRF Urine Test • Elevated TE (microbial degradation) • LH < 0,1 mIU/ml; • Norandrosterone, Noretiocholanolone (high) • Drostanolone (metabolite,low) Hair Test • Boldenone (6 pg/mg), • Clenbuterol (6 pg/mg) • Metandienone (9 pg/mg), • Nandrolone (7 pg/mg), • Testosteron-Propionate (7 pg/mg) • Testosterone 6 pg/mg > normal Summary • Hair Testing lacks sensitivity but gains retrospection. Follow up possible weeks after urine test (if hair is available) • (Dark) hair concentration of clenbuterol are comparatively well dose related. • High Discrimination Power between Low (5*ADI) and Hi (Abuse) cases. • A proposed threshold of 1…5 pg/mg clenbuterol in hair could contribute to discriminate most of the pending clenbuterol cases. • Increasing reporting levels of clenbuterol would cause potential disregarding real (even excessive) cases. • Estimated Clenbuterol Contamination Dosages in high risk areas (Mexico) correspond to administrations in the order of magnitude of 2 * ADI.
