StimuMAX Black Edition, the unrivalled pre workout designed for your most intense and heavy sessions. This powerhouse formulation is not for the faint-hearted. We still have the ingredients you will recognise from the StimuMAX OG; Citrulline Malate, Beta Alanine, NAC-L-Tyrosine, Juglans Regia and Caffeine. To that we added Kigelia Africana Extract to make it even more powerful.
