Health Canada is advising Canadians that the unauthorized health products “Black Mamba 2 Premium” and “ExtenZe” are labelled to contain drugs that may pose serious health risks (DHEA, pregnenolone, and yohimbe/yohimbine). Health Canada seized the products, which are promoted for sexual enhancement, from Yonge and John Medical Pharmacy at 7670 Yonge Street in Thornhill, ON.
