Normal insulin with undetectable C-peptide concentrations indicates exogenous insulin administration in a bodybuilder (1 ). Insulin has anabolic functions that inhibit breakdown and promote nutrient storage (2 ). Pharmaceutical-grade insulin is available without prescription, providing an easy-to-obtain performance enhancer (3). Although a urinary testosterone/ luteinizing hormone ratio 30 is a...

As well as athletes and competitive body builders, recreational body builders attending gymnasia are known to abuse anabolic steroids, using doses from 10- to 40-fold above physiological levels. Androgenic steroids induce hypogonadotrophic hypogonadism with associated azoospermia, leading to infertility.

The use of the Agilent LC/MSD TOF, an orthogonal-axis time-of-flight (oa-TOF) mass spectrometer, equipped with an atmospheric pressure chemical ionization (APCI) source, is described for the analysis of four anabolic steroids and one internal standard, in urine extracts at a 1–2 ng/mL concentration. The high degree of mass accuracy (<3 ppm) of the TOF instrument allows for both excellent confir...
