I found an interesting read yesterday, but didn't bookmark it. I don't know where the fella got his info, but he wrote about how tb500 works. The interesting thing, being I am using EQ, was when he talked about the effects of EQ on tendons. In a nut shell he was saying EQ causes a 300% increase in type 1 collagen, which is used by the body to make new tendons. The TB500 increases type 3 collagen, which the body uses to repair existing tendon material. The type 1 collagen and new tendon material can be helpful in long run, but that new material is easily injured and does nothing to repair injuries. The type 3, increased with TB500, is what heals those tendon injuries. He states combining EQ and TB500 makes for the best way to strengthen tendons and repair tendonitis. He didn't address any of the other claims of TB500.
