I would definitely have deca in the mix if they aren't testing for the feel good nature of it, improved callogen synthesis and bone mineral content. As a fighter I'm sure your body feeling good will go a long way in the ring especially from a mental standpoint. Improved red blood cell count is going to boost endurance and carry more oxygen. Enhanced protein synthesis, IGF1 and nitrogen and the reuduction in the glucocorticoid hormones is going to drive endurance.
