IMPORTANT NOTICE: WADA-prohibited substances detected in Koshiki Bainiku Extract

Thank you for your loyal patronage of Meitan Honpo Super Athlete products.  We wish to inform you of important information.  The UK's LGC has tested the following products for the presence of substances prohibited under WADA anti-doping regulations.
  • Koshiki Bainiku Extract
  • Top Condition (TC)
  • Meitan Super Extra Gold
  • Meitan Extra Gold
  • Meitan Cycle Charge (CC)
  • Cycle Charge Caffeine Plus (CCC)
  • Cycle Charge Caffeine 200 (CCC200)
  • 2Run
  • Electrolyte Powder
Test results revealed the presence of 1,4-androstadiene-3,17-dione [also known as boldione] in Koshiki Bainiku Extract.  Specific test results for Top Condition have not yet been received.   The other products listed above have been confirmed to be free of prohibited substances, but because the following products include Koshiki Bainiku Extract as an ingredient, to be safe, athletes subject to doping control should stop taking them.
  • Koshiki Bainiku Extract
  • Top Condition (TC)
  • Meitan Super Extra Gold
  • Meitan Extra Gold
  • Meitan Cycle Charge (CC)
  • Cycle Charge Caffeine Plus (CCC)
  • Cycle Charge Caffeine 200 (CCC200)
Please note that 2Run and Electrolyte Powder have both been cleared by testing and do not contain Koshiki Bainiku Extract and are safe for athletes subject to doping control to use.

The results above are the results of screening testing only, so preparations are currently underway for more detailed secondary centrifuge testing of the Koshiki Bainiku Extract used in the Cycle Charge group of energy products.  We will post the results as soon as they have been reported.

The reality is that major international marathons use a bicycle to measure the distance.  This rule is an international standard, and the same method of measurement is used everywhere.  It was put into place in 1986.  In order to ensure that the same method is used everywhere, a bicycle that meets IAAF specifications must be used for measurement. In the case of Japan's major marathons, to be certain that the distance is correct a provisional measurement is first made.  Before the course is certified using a bicycle the course is measured using a 50 m-long length of wire to determine that it is in fact 42.195 km.  When a bicycle is u...
