GAS6, the new molecule doped?
Monday, July 15, a tweet (since deleted) repented of Swiss rider Thomas Frei (formerly BMC) had the effect of a stone into a pond: "Hey, guys, you know GAS6 - Growth Arrest - Specific 6 ? ". In the process, a user launched this molecule was used successfully in the 2013 Giro. Then a rumor widely reported, announced that Geert Leinders, the doctor "fired" by SKY last year (because of its implications in the doping network Rabobank), had worked on the development of person GAS6 university Leuven. It did not take more for this product, previously completely unknown to anti-doping, is the star of the day. Marc Kluszczinski, subject expert, author of the "on the front of doping" in Sport and Life magazine, had the extreme kindness to write an overview of products that are widely circulated in the nose and platoons beard controls.

EPO is not what it was: the new test maiia (Membrane Assisted Isoform Immunoassays) appeared in early can detect the use of micro-doses. It is an effective addition to the EPO biosimilars. It's fast and easy to use (20 minutes for 56 samples), while the first test of the year 2000 called for three days and was expensive, its interpretation remains difficult (remember samples Lance Armstrong in the Tour de Suisse 2001 and DL 2002). Surprisingly this year's TdF, runners returned to the ranks such Alberto Contador (attacks not have the same bite!) And Andy Schleck or Joaquim Rodriguez, all less sparkling than usual.
And autologous blood transfusions? Still undetectable, but the risk is big to make make a pocket during a rest day on the Tour, with it seems, who rode around the OCLAESP trucks, motor homes and hotels. But it would have been ordered not to trigger an earthquake during the 100th edition, filled with happiness to millions of viewers with its unforgettable landscapes, accompanied by no less memorable explanations. Interesting times of economic crisis, the Tour is traveling the French who can not go on holiday! We forget the crisis, the news and the Tour continues in an atmosphere poisoned, so much so that Bernard Hinault does not stop farting cables. We should stop talking about doping in cycling! But the start of Chris Froome in the climbs Ax-3-Domaines and Ventoux, its too great superiority over its rivals, its not far from those estimated years Pantani and Armstrong powers, the lack of open communication its athletic director, we fear the worst.
Better than the TB 500 and EPO together!
Yes, new products exist. Some are on the rise, such as growth factors. They are already included in the category of S.2 substances banned by WADA, but often treated as single vitamins by their users. On the eve of the 2011 Tour, Wim Vansevenant, then driver from Omega Pharma-Lotto, was arrested by the Belgian customs, the parcel TB 500 has been intercepted. The TB 500 is a peptide of 43 amino acids which acts on muscle development and vascularity of muscle, resulting in improved yield stress. Although these properties were observed in animals that experience, Dr. Alberto Beltran Nino already arrested him in March 2012 in Madrid airport when Skype operation of the Guardia Civil. In his luggage, had been found AICAR and TB 500.
AICAR and precisely? It is detectable and would not be effective alone. It should be combined with agonists of PPAR δ and γ that direct metabolism to use fat (GW 501516) molecules that are dangerous to the point that the AMA has taken care to warn of its dangers cheats last March. That has not stopped seven cyclists getting caught in March, six South American and Russian Valery Kaykov (RUSVELO).
But it was found better than the EPO and the TB 500 combined! Growth factor-6 GAS (Growth-arrest specific-6) promotes the secretion of endogenous EPO and vascularity. Studies have even shown in 2008 that the GAS-6 could replace the administration of EPO in anemic patients. You can bet without risk that the substance is already used in professional sports, not just cycling. And as always, we invoke the excuse of altitude to explain the increase in red blood cells. Poor blood passport!
Other options currently exist to increase the level of red blood cells without the use of exogenous EPO and without attracting the attention of radars (one is located in a well doping recovery smoothness doping). Inhibitors of HIF 1α prolyl hydroxylase mimic a state of hypoxia in the body and are secreted endogenous EPO. And how not to speak of thyroid hormones on 10000m by Mo Farah and Galen Rupp who made the first and second at the London Olympics? These hormones are not on the WADA list, have a lipolytic effect, stimulating and induce secretion of EPO! And if that was the secret of SKY, their "marginal gains"?
To darken a little table, talking about the growth hormone (GH) has left so many bad memories of Alex Zülle, Bjarne Riis or Tyler Hamilton. Hormone record holder of non-detection (over 25 years) is exceeded. It comprises 191 amino acids and is present in one hundred forms (isoforms) with very different properties. Two avenues are explored: isolating the active fractions or act upstream on the secretion of total hormone. Australian a laboratory succeeded in isolating the lipolytic fraction, a 15 amino acid peptide representing the C-terminus of the total GH. This peptide is found in the system of veterinary medicine and the Internet. Secretagogues peptides (GHRP-2 Hexarelin ...) are undetectable. WADA has to worry about the doping and still has good days ahead.
