Maybe the biggest guns right now.
Look at the forearms, doesn't add up.
Look at the double bicep pic he has good forearms. In the first pic he is not in competition shape, so you will get fat on your upper arm, but not on your forearms.
Still think he's got a lot of oil in those arms.
I think it is more that he shoots alot of oil based products in them. They like the site injections, even though the pro gh15 uses his ass only.
Kyomu would know but I doubt he would divulge the truth.
