Absolutlely every pro team use them at this point... At different points in time the UCI has said the both EPO and testosterone provided no benefit as well... LMAO...

As I eluded to the early studies that tested performance based on 1hr TT showed no effect or even impairment... recent studies that pair ketone ester with bicarbonate and mimic actual race situation do show significant performance benefit. When the performance was tested after 3hrs of moderate exercise and ketones paired with bicarbonate there was significant performance benefit.

I will find you links to the research.. UCI WAY behind as usual...
