I did my local 3 minute hill climb yesterday that I use for hard vo2 max type intervals. My power was the same as last week BUT I am now using a crank power meter vs hub power meter. I felt stronger as if I could have paced another 5 watts. I know I was stronger because there was a 15-20 mph headwind and my time was identical. At about 90 seconds, there is a 14-18% wall that just kills me and then it flattens out to 6-8% to the red barn finish line. What I noticed is less difficulty keeping the power down after the wall.

Is this possible? Or placebo?

Vukovich and Geri showed 8-9% increase in VO2 with just 2 weeks of 3 grams per day.
