Tanner? You mean, Jas, he has Tanner in his avatar. He's a homosexual, but he's still pretty cool. I personally wouldn't grapple with him, just saying.
I don't train in BJJ or MMA. Rodja is the only pro fighter on this board and I'm sure he'll chime in and recommend some vids and supplements. I train pretty much powerlifting style so the supps I use may differ a little. Beta-Alanine is a winner, should help with endurance and give a nice strength boost. I also like a supplement called Cordygen 5, you can go look into it in the Millenium Sports section. They're good guys and IMO, Cordygen5 helps with cardio even though I don't do a ton. For Protein you should probably go with EvoPro by Cytosport or Whey protein by Optimum Nutrition. Both are relatively cheap and are a good quality protein supplement. Rodja should chime in and will probably add some good suggestions. You can buy cheap supplements at NutraPlanet, and you can get the Beta-Alanine in bulk which is a great deal.
Do you watch a lot of MMA? Either way stick around for some good conversation.
