The BHA has today issued an update on the following products, which our testing on several samples has shown contain traces of Category A substances. We advise that trainers and veterinarians read and follow the information and guidance provided below.

A reminder that any product advertised as being herbal in origin does not guarantee that it is free from prohibited substances. More generally, we strongly recommend that trainers only use accredited supplements that comply with the British Equestrian Trade Association’s (BETA) NOPS scheme. More information about this is available here.

We will continue to keep trainers updated as soon as we have more information to share on any of the products referenced below. For any immediate questions, please contact: [email protected].

HOMOPLUS

Homoplus (Peak Performance Nutrition) is available as a paste and marketed as a herbal supplement for use in horses prone to bleeding during exercise.

Several batches of this product have been analysed by the LGC laboratory, and this has confirmed the presence of GABA (Gamma Aminobutyric Acid) in each of the samples tested. GABA is considered a Category A substance that is prohibited at all times under the Rules of Racing.

Despite attempts to contact the manufacturer and supplier we have received no response to date. Therefore, the source of this substance in the product is unknown.

We are therefore advising that trainers do not use Homoplus, as the samples we have tested contain a substance that is prohibited at all times under the Rules of Racing.

LUNG XL AND HEMOREX PASTE

The BHA contacted trainers in November 2025 to advise against the use of Hemorex Paste and Lung XL, as our analysis of product samples has confirmed the presence of 20-hydroxyecdysone, a Category A substance.

Trainers must not use or possess these products, as our engagement with the manufacturer has not been able to satisfy us that they do not contain a substance that is prohibited at all times under the Rules of Racing.

Furthermore, please ensure that these products are removed from licensed premises with immediate effect. If these products are found in yards, then they will be tested and the trainers will be at risk of a breach in the Rules of Racing for possession of a Category A substance.
