have you seen jereem richards's progression .
2015 - 20.72 no 2016 then 2017 - 19.97 ...........former 46 flat 400m
i dont know of any androgens that can do this
lacks the muscle to suggest so and of the tall long legged type athlete
that perfect for the speed peptide.
regardless of wada's and media's absolute non discussion of it
have to admit that some ped out there responsible and not steroids
it is as said the speed peptide
and every single one of athletes in 200m was on it at very least
wada are the problem and their to control doping how ever exists at any time
and m. johnson is no saint , was usatf darling for along time
