Trapper is the bionic man. Often he goes beyond the existing protocol to report back what he has experienced. It's not for everyone...but Trap is a pretty clean and healthy guy considering where he came from. His body seems to take quite a bit (it takes a licking and keeps on ticking). Because he has reached a pretty decent level of internal health, I think he can handle more than most. I think you read that he did start seeing colors, etc?
I would never suggest anyone do 10 pulls back to back unless you are zeroed in on major self-experimentation. Each of us are different, as different as snowflakes. That is why you had the reaction you did with 4 pulls, which is actually quite a bit. I don't usually do that unless I'm fighting a brochial thing.
I would think that if you did 10 pulls back to back perhaps your upper lip would have fallen off your face - LOL...just kidding.
I read what Trap does and then I cut it by thirds if I want to push the envelope. He's an amazing guy.
