I have searched high and low through the AHRC rule book and HRV local rule amendments and I can not find a rule that bans cobalt chloride or defines the measurable threshold. HRV are saying they have got a positive swab for cobalt, I cannot see how HRV can charge a trainer for using cobalt if there is no rule or threshold against it. Im wondering how HRV can charge a trainer, under what rule can they charge them for using cobalt?
