I read an article about Peptide (i think) use by Jumbo Visma. Totally legal but not used by some teams and used by others such as Ineos and QuickStep.
Those are Ketone supplements used by J-V team. They supposedly spare glycogen by getting the body to convert fat into a more immediately usable form of energy for higher % efforts than fat would normally be good for.
It basically mimics the ketosis state that a no carb diet places the body into, without the need to cut carbs from the diet. As far as I know, there's limited evidence this actually works.
