The chief executive of the AFL Andrew Demetriou says he's shocked by allegations Essendon players were injected with a variety of bizarre substances.
The former Essendon sports scientist Stephen Dank says Essendon players were given an anti-obesity drug, an extract from pig's brain, the first milk from a mother cow and a bark extract.
But Dank says nothing he gave the players was prohibited and stressed the supplements were safe.
Demetriou says he horrified at what's gone on.
The club is being investigated by the Australian Sports Anti-Doping Authority as part as on going investigation over supplement use in Australian sport.
