The state Board of Examiners for Nursing on Wednesday disciplined three nurses, including one who dealt in anabolic steroids. In the steroid case, the board fined RN Michael Mase of New Milford $3,000 and placed his license on probation for a year. He has said he started using steroids in connection with power lifting and that he bought them for his own use and to share with friends, records show. In 2015, he pleaded guilty to one count of conspiracy to distribute and intent to sell steroids, records show, and is now on criminal probation through 2018. Under the consent order he signed with the nursing board, Mase must undergo random drug tests but he can stay employed as an independent contractor with Vivacity Life Center in Stamford.
