I'd never heard of 2,4 DNP, so I looked it up. Nasty stuff, and I can't see how it would help performance. Apparently it reduces body fat, but has been deemed too dangerous to use since 1938. https://en.wikipedia.org/wiki/2,4-Dinitrophenol

It's a weight loss drug. I've done a rough categorization of the full list here: https://news.ycombinator.com/item?id=16777656

As far as why it counts as "doping" — it is probably used by body builders to drop body fat to competition levels. Anecdotally, without chemical help you are hungry all the time at 4-8 %bf.

Also, the common wisdom among runners is that body fat is dead weight and losing it makes you faster and reduces load on your joints. So it may help there too. Cyclists probably see less benefit, but less fat may help acceleration and hill climb ability.

Yes this article confirms that professional cyclists in the Tour de France are under 6% and hungry all the time. But they have to be careful not to go too low or they run the risk of getting sick and dropping out of the race.

Yeah. In running there is some belief that it may be safer and healthier to train at less extreme %bf in the off season, and only drop to extremely low %bf shortly before and during the race season.

For those sports where there are weight classes, losing 5-10 pounds rapidly can move you from a weight class we're your average to a weight class where you dominate.

DNP is really nasty shit. It's very popular for bodybuilding because it really does work great but you can get yourself into serious trouble if you aren't careful.

Also running dnp in the summer is not something you want to do. Your body heat goes up like crazy and it's miserable in the summer.

The drug itself is just a dye basically and it will ruin everything it touches.

If you want to know more about DNP search /r/steroids for it. There's endless threds and posts about it's use.

I'll take a lot of stuff, but DNP is the one I won't touch.

Generally for most endurance sports, losing weight is gaining time. It's why one might see someone using a cocktail of drugs, some to help with endurance/O2 uptake others with lowering weight to affect both sides of the power/mass ratio.

not used for performance. used by bodybuilders to cut before competition
