Even more difficult to identify the use of peptide hormones and their analogues. Michael J. Bender has similar goals. In this class, the most frequently used human chorionic gonadotropin, erythropoietin and human growth hormone (somatotropin). “The actual scope of their use is unknown because of the rapid metabolism and subsequent output in the urine. Even the exact structure of the isolated compounds is usually unknown. There are no relevant internationally recognized reference materials in order to generalize the results achieved by different techniques in different laboratories. Quantitative concentrations found in one laboratory, almost comparable to those obtained in others. It is always difficult to establish a clear criterion to distinguish the exogenous application of (banned) from the normative endogenous concentrations. The structure of the peptide detected must be confirmed by mass spectrometry.

In modern times it requires great effort, although the new technique of ionization, new interfaces with chromatographic or electrophoretic systems and the evolution of ionoanalizatorov will contribute to the solution of this problem in the future (Segura, 2003). “Consumption of human chorionic gonadotropin (hCG) is constantly described as a means to achieve the release of androgenic and anabolic compounds of testosterone, which can be useful to improve performance (power and force) in Sports higher achievements. Consumption of hCG with a corresponding increase in testosterone and epitestosterone its inactive isomer, does not lend itself to existing methods of detection of testosterone abuse, which are based on measurement of the coefficient between the two isomeric compounds (Segura, 2003). Imperfection of the anti-doping laboratory confirmed by other facts. It is known that the IOC has been accredited, and in 2001 – 2003 gg. worked 24-30 anti-doping laboratories. However, they were loaded with extremely disproportionate. In particular, in 2001 the laboratory conducted in Los Angeles 27 436 surveys, Cologne – 10 634, Sydney – 7433, Seoul – 623, Moscow – 997 surveys. This can be explained state of logistics, staffing and other reasons, though, in our view, this situation is not normal.
