The original Methyl 1 test put out by LG science was prob the strongest PH ever made. It was a 17a methyl 1 testosterone derivative. The problem was it was highly liver toxic but I know I read an article years ago that the pure chemist aka Patrick Arnold the godfather of PH's said it was 7 times more anabolic then synthetic testosterone. I cycled a bunch of it in the early 2000s. 2 weeks on 2 weeks off. Had patches of hair fall out. **** is no beuno.
