So you find it NECESSARY?
I'm talking about the main basics of what he needs. There is no reason to be taking pills if everything else isn't in check.
In my eyes: results = diet 80%, routine 15%, supplements 5%.
If he has everything exactly in check with his diet and routine then I would consider supplements. Most people half ass on their diet, and their routine sucks. That's 40% + 10% = 50% less results.
I was referring to people that are training at same or almost the same level as real UFC fighters.
I would say 2% supplements.
