There are power lifting federations where they are not tested which can give you some information. PED seems to increase strength between 5-20 percent with most around 10% probably.

If you want watch people go all out with AAS, HGH, insulin and all that you can watch modern bodybuilding.

By the way, that's not a 10% increase in individual performance, but rather a 10% increase in relative performance for your weight. People on PEDs will usually move up a weight class from increased muscle mass.

Edit: See here for a really detailed comparison from someone who knows what he's talking about: https://www.strongerbyscience.com/steroids-and-strength-diff...

Imagine if you did have the two classes in an endurance race, with no prize money for the doped up classes. Imagine in cycling if there was Lance and co doing the Tour we know and then another clean race, much like in Learning Mans with motor sport. Lance and co would be the LMP class.

As per motor sport it is obvious what class a car is in, there is no pretending to be the other class.

The testing would be more part of signing up to a given class, everyone would know what everyone was taking whether that be nothing or everything. Much like how in Motorsport you know cylinder count, oil used and so on.

I'm with you on this. I'd be really interested in seeing, for example, an "Open Division" in Track-and-Field, whereby anything goes, up to and including gene modification and cybernetic enhancement.

It would be both a sport and a laboratory for transhumanism. I'd be incredibly interested to see what science came out of it.

There are probably ethical arguments to be made against doing that, but... meh.

PRIDE fighting in Japan explicitly does not test for anything.

they haven't been around for a while. I don't think ONE championship tests, and if they do, it isn't very rigorous.

In MMA the UFC is way way more strict than any of the other orgs. You very rarely see champs or big celebs pulled off card ever like you in the the UFC under USADA testing

Rizin FF[1] is the new PRIDE, in essence. It too has a 'relaxed' stance on PEDs.

And a 'relaxed' stance on stupid matches. Not a fan of the org after the Gabbi Garcia shenanigans

PRIDE has its fair share of preposterous exhibition matches though, to be fair. But no, I'm not a fan either.
