performance enhancers

[firstborn]

Anyone have any experience of or comments on performance enhancers (if thats what they are called) such as Viper Turbo. And performance related to sport - marathons, ultras etc and not anywhere else

I would say it's one of the cases of try it and see.


I'm assuming other scientific studies show it doesn't have any effect.

There are plenty of these things around, some people say they are amazing, others say they feel no effect from them.

My feelings exactly tbh - might give it a go though prior to my sahara jolly as a few people have used it out there and swear by it
