Promera Sports and the CON-CRET® brand are deeply rooted in rigorous science and dedication to quality.

Promera’s parent company, Vireo Systems (named for the Latin word for health and vigor), was formed in the culture of pharmaceutical science and forensic toxicology, where the highest standards of formal research and scrutinized certifications are required. Those standards have been the driving force behind our innovation, and the bedrock of our reputation as one of the most trusted brands on the market.

The company began in 2002, with university-based scientists studying and testing amino acid conjugations. On January 23, 2003, Vireo made a fortuitous miscalculation with a batch of acid catalysts resulting in the formation of the molecule that would become CON-CRET®.
