Independent Arbitrator Imposes Four-Year Sanction on Chi Lewis-Parry for UFC Anti-Doping Policy Violations

UFC glove next to the UFC Anti-Doping program emblem logo.USADA announced today that an independent arbitrator has rendered a decision in the case of former UFC® athlete Chi Lewis-Parry, of Surrey, United Kingdom, and determined that Lewis-Parry should receive a four-year period of ineligibility for anti-doping policy violations that he committed while he was in the UFC program. This decision comes after the facts of the case were presented and fully argued at an evidentiary hearing on November 10, 2020.

Lewis-Parry, 37, tested positive for the following substances as the result of out-of-competition tests on September 12, 2019 and September 19, 2019:

  • Drostanolone and its metabolites 2α-methyl-5α-androstan-3α-ol-17-one and 2α-methyl-5α-androstan-3β,17β-diol;
  • Stanozolol metabolites 3′-hydroxy-17-epistanozolol-O-glucuronide and 3′-hydroxystanozolol-O-glucuronide;
  • Metabolites of dehydrochloromethyltestosterone (DHCMT) or similar 4-chloro-17α-methyl substituted anabolic steroid

The above are non-Specified Substances in the class of Anabolic Agents and are prohibited at all times under the UFC Anti-Doping Policy and UFC Prohibited List.

Upon being added to the UFC Anti-Doping Program, athletes are required to declare prohibited substances they have used in the previous 12 months. An athlete who makes such declaration will not be deemed to have committed a violation but, depending on the substance, may be required to refrain from competition for a period of at least six months and provide at least two negative samples. Lewis-Parry did not declare the use of drostanolone, stanozolol, or DHCMT on his onboarding declaration forms. Subsequent to his positive tests but before competing in any UFC bout, Lewis-Parry was released from the program.

In its investigation into the circumstances of the case, USADA also discovered that Lewis-Parry presented falsified evidence, specifically an adulterated supplement, to USADA and the arbitrator in support of the athlete’s claims that the prohibited substances had originated from a contaminated supplement.

Under the UFC Anti-Doping Policy, deceitful or obstructive conduct intended to avoid the detection or adjudication of an anti-doping policy violation may be regarded as aggravating circumstances, which can lead to an increased period of ineligibility. In this case, the independent arbitrator concluded that Lewis-Parry’s conduct warranted an increase from the standard two-year period of ineligibility for a first offense, to the maximum four-year period of ineligibility due to aggravating circumstances.


The arbitrator concluded, “[a]lthough the 4 year period where aggravating circumstances are present is a maximum, not a mandatory period I consider on the basis of the facts as I find them, that [Lewis-Parry] has sought to muddy the waters from first to last both prior to and during this Arbitration by provision of false evidence. 4 years is therefore in principle proportionate and appropriate.”

Lewis-Parry’s four-year period of ineligibility began on November 1, 2019, the date on which he was provisionally suspended from competition. The arbitrator’s decision can be found here, along with all other UFC Anti-Doping Policy arbitral decisions.

USADA conducts the year-round, independent anti-doping program for all UFC athletes. USADA is an independent, non-profit, non-governmental agency whose sole mission is to preserve the integrity of competition, inspire true sport, and protect the rights of clean athletes. In an effort to aid UFC athletes, as well as their support team members, in understanding the rules applicable to them, USADA provides comprehensive instruction on the UFC Anti-Doping Program website (https://UFC.USADA.org) regarding the testing process and prohibited substances, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements, as well as performance-enhancing and recreational drugs.

In addition, the agency manages a drug reference hotline, Drug Reference Online (https://UFC.GlobalDRO.com), conducts educational sessions, and proactively distributes a multitude of educational materials, such as the Prohibited List, easy-reference wallet cards, and periodic athlete alerts. Many of the resources available to athletes are provided in multiple languages, including Russian, Spanish, French, Portuguese, Korean, and Japanese.

Along with education and testing, robust anti-doping programs enable investigations stemming from tips and whistleblowers. USADA makes available a number of ways to report the abuse of performance-enhancing drugs in sport in an effort to protect clean athletes and promote clean competition. Any tip can be reported using the USADA Play Clean Tip Center, by email at playclean@usada.org, by phone at 1 877-Play Clean (1-877-752-9253), or by mail.
