He doesn't look like he's on TRT. You can be natural and be ripped as you get older. You'll just be much smaller if your testosterone level is low. 170 at 6 feet tall is pretty small.
True but that's a killer athletic body. Around the height and weight for so many MMA guys. Yes, he is swims for cardio. I know from a bodybuilding stand point the size is missing. The reason I thought he was on TRT because I had a vague recollection he said that in an interview but I can't say for certain. Am I wrong but isn't TRT just very low dose test that is prescribed to grandpa's? It doesn't do much for bodybuilding at that dose.
