Major Updates to the 2024 List 

The 2024 list brings with it important changes and additions. 

Among them, the inclusion of new anabolic agents such as Trestolone y Dimethandrolone, thus expanding the category of nandrolone analogues. 

In addition, adjustments have been made to the peptide hormones and growth factors section, adding substances such as Kisspeptin and its agonist analogues, which stimulate the secretion of GnRH and, therefore, the production of testosterone. 

In the area of ​​stimulants, it has been added 2-phenylpropan-1-amine (BMPEA), a substance commonly present in dietary supplements, and the list of narcotics prohibited in competition has been updated, now including Tramadol.  

This latest addition responds to studies that confirm the potential of tramadol to improve physical performance, which has led to its ban in competition from 2024.
