New and improved for quicker recovery.

First Endurance’s Optygen HP will help you train harder and recover faster by improving oxygen utilization, which increases your body’s ability to adapt to physical stress and a higher aerobic threshold. The improved formula of Optygen HP features Rhodiola (tested to improve mental and physical performance) that’s twice as strong as the original formula. In addition to Rhodiola, Optygen HP includes Beta-Alanine, with a 1,500mg of Beta-Alanine per serving. Beta-Alanine has been tested to increase muscular endurance, boost strength, exercise capacity, and to delay muscular fatigue.

  • New HP formula improves recovery with less front loading
  • Increases oxygen utilization
  • 1,500mg of Beta-Alanine per serving

Wow...That Actually Works.

  • Familiarity: I've used it several times

For a supplement with some sleek packaging and well crafted marketing message, heading into this I was bit skeptical. Package states you have to give it about a month to feel the effects, and while I didn't notice any major difference a week or two weeks in, the 3rd week is where I really started to reap the benefits. I'm no exercise physiologist, but I am a bike rider and using this product after a month has made me a better bike rider. Improvements in threshold power, more efficient recover blocks and better times on all the local climbs are evident that along with structured training, rest, and diet Optygen HP is just that extra edge.

It is no doubt expensive, but it could be that extra boost you need going into your main event for the year.

  • Familiarity: I've put it through the wringer

I'm not exactly sure what kind of magical potion is in these little red pills, but I definitely feel an edge at higher heart rates when taking them. Sure are expensive for a daily supplement when training though.
