I Know GSP is sponsored by Biotest but are any other fighters on Bio’s payroll?
Not sure about fighters but they sponsored (or had the cage mat advertisement for the TKO-29 event in Montreal a couple months ago.
I thought it was a weird place to advertise since they can only sell the caffeine-free version here (although you can order it in). Nonetheless, it’s nice to see the Biotest products out there getting publicity.
