Rivalus is a North American supplement brand known for clean, Informed Sport certified formulas — particularly appealing to competitive athletes in drug-tested sport who require third-party banned substance verification on every product they use. Rivalus operates on a commitment to clean sport: every product in their lineup is certified by Informed Sport, providing assurance that no banned substances have been detected in any batch. Bulldog Nutrition is an authorized Canadian and US retailer of Rivalus, backed by 10+ years in the supplement industry.
Rivalus products include Promasil (a multi-source protein blend with whey, casein, and egg) and Clean Gainer (a mass gainer formula using whole food carbohydrate sources rather than maltodextrin). The clean sport focus makes Rivalus particularly relevant for athletes subject to regular drug testing — military, collegiate, professional, or competitive amateur athletes who cannot risk a failed test from a contaminated supplement.
Why Rivalus for drug-tested athletes: Informed Sport certification involves testing every batch of every product for banned substances — not just formula certification. For athletes where a failed drug test carries serious consequences (career, eligibility, reputation), Informed Sport certified products provide meaningful risk reduction beyond uncertified alternatives.
