There's Nolotil. Even Chad N. has talked about it, said it worked best if the muscle was pumped a lot before going on stage.
I find it incredible that a man like bob, who has been around the sport for what, 27 years, has only heard of esciline (outdated) and synthol as the only two site injection products.
Bob, i admire you for avoiding the shady side of the sport all these years.
