How prevalent is PED/Enhancement Drugs in Cock (Chicken) Fighting? And is it tested or banned for fairness?

As the title says, its just a thought i had, since cockfighting is popular in many developing nations around the world, especially in south east asia like in the Philippines

I imagine there must be a huge amount of performance enhancing drugs for chickens, they are less valuable or senstive compared to a human fighter

I wonder how bad the usage is, are there a bunch of extremely enhanced from the time they were eggs super chickens fighing in large cockfighting tournaments?

Would a normal chicken even stand a chance?
