The high quality TWYDIL® programmes ensure that your horses achieve sport performances as close as possible to their full potential.

TWYDIL® remains worldwide the only company to undertake antidoping controls on each batch of the product before release. An overdose of a representative sample of each batch of the finished product with the respective formulas is given to a horse and its blood and urine are tested for a range of forbidden substances. The institution in charge of the tests is the LCH (Laboratoire des Courses Hippiques).

On April 4, 2011 the FEI (International Federation of Equestrian Sports) published a list of
prohibited substances that should not test positive during controls, see
