The U.S. Anti-Doping Agency announced on Tuesday that Jake Collier has accepted a 10-month suspension term after he declared the use of a product that listed and contained a prohibited substance, and subsequently tested positive for that substance.

Collier (11-4 MMA, 3-3 UFC) tested positive for Higenamine as the result of an out-of-competition urine sample he provided Dec. 27. According to the USADA release, Higenamine is “Specified Substance in the class of Beta-2 Agonists and prohibited at all times under the UFC Anti-Doping Policy, which has adopted the World Anti-Doping Agency (WADA) Prohibited List.”

The release continued with more details about the substance, as well as the circumstances which led to Collier’s suspension.

Research indicates that Higenamine may act as a general stimulant and may be found in some pre-workout, energy, or weight-loss products. Even low-risk supplements may be riskier than they appear. As such, USADA reminds athletes to check supplement labels for Higenamine (also known as norcoclaurine) or Higenamine plant-based sources (Aconite, Annona squamosal, Nandina domestica, Tinospora crispa, and others). USADA determined that Collier was eligible for a reduction to the otherwise standard one-year period of ineligibility due to his cooperation throughout the results management process and forthright declaration of the supplement on his doping control form.

After the news was announced, Collier, 30, took to social media to release a statement. He said there was no ill intent on his behalf (via Twitter):

To my fans and supporters, I jut wanted to touch base with you after the news has been announced of my sanction. First of all, I would NEVER purposely put any illegal substance in my body to gain a competitive edge. I’d rather lose than cheat. Returning from a surgery after an injury in my last fight, I went out to the local supplement store and purchased a pre-workout that was recommended by their staff that I have worked with previously. Unfortunately, there was a substance in the product that was listed on the label and on the USADA prohibited list that we were unaware of. For that simple mistake, I have accepted a 10-month suspension. During this process my wife and I have already taken action in learning the proper system to research produce names and ingredients. This has been quite a learning lesson and I take full responsibility for my mistake and apologize. Thank you to my team, my management @EmpireSM, Donna Marcolini and Jeff Novitzky with UFC for their continued support. I can’t wait to get back to work in the octagon.

Collier hasn’t competed since a unanimous-decision victory over Marcel Fortuna at UFC Fight Night 120 in November. He has alternated wins and losses over his six-fight tenure with the organization, which began in December 2014.

The suspension runs until Oct. 27, at which point Collier will be eligible to return to competition.
