Came across a repost on instagram of Mo Katir promoting a supplement company named SC Nutrition Europe? When I looked on their instagram profile it checked out. On the website it lists two products as Katir's go to supplements- the 'blood booster' seems like it is riding a pretty fine line? I've linked the product below.
Any doping experts care to explain how these products are 'doping free' as described on the web site?
