A study done by Dr. Andrew Creer (2007 South Dakota State University) showed Optygen reduces cortisol levels (the primary stress hormone) by 26%. Researchers concluded that Optygen is beneficial for trained athletes undergoing high training volumes because it decreases baseline stress and improves training sessions. Cortisol is a catabolic (breakdown) hormone that the body produces when under stress, such as after hours of running. Chronically elevated cortisol levels can prevent an athlete from recovering, increase the risks of overtraining and supress the immune system.
Another study done by Dr. Karlton Larson (2007 Luther College) showed endurance athletes who used Optygen increased the time to lactate threshold by 42%. Results of this study show Optygen is effective in reducing lactic acid production and delaying onset of lactate threshold (the exercise intensity at which lactic acid starts to accumulate in the blood stream), therefore improving endurance.

Well, I have to say, I’m 100% in. I’m a believer. I am the manager of Performance Bicycle in Redmond, WA, and I’ve tried every supplement, all of them are complete bull except electrolyte replacement and Optygen. I took Optygen prior to my last Half-Ironman, and I was amazing on the bike, even catching the leaders by the end of the bike section. Optygen is amazing,

Hey Mike,
Thanks for the feedback. Have you tried Ultragen yet?

I was turned onto Optygen in 2006 and it has never failed me during training, or competition. I have introduced numerous clients to 1st Endurance over the years, and they have routinely utilized EFS, Ultragen and Optygen in their supplementation programs with awesome results. The customer service and knowledge base within 1st Endurance is also an excellent resource for athletes.

Mike, would you mind posting the studies referenced in your first post? Study size and methods are very important. Also, the statistics seem to be a bit misleading. Does delaying the introduction of lactic acid into the blood stream by 4-5 seconds really make a huge difference in an endurance workout? Once lactic acid is in the bloodstream, it will be there for the entire workout. How much does it matter if that starts at 12 seconds or 16 seconds after the beginning of the workout. Also, is there any real-life difference in a cortisol level of 0.8ug/dL vs. 1.2ug/dL? Normal daily levels can be as high as 30 ug/dL in a normal adult. Just some thoughts from a real scientific standpoint. Thanks, Jim

Jim,
A complete research packet can be found for each of our products by going to our product page and linking to research packet. Here you will be able to gain all the detail each study and on both the cortisol and time to onset of lactate threshold. Both double-blind, placebo controlled studies proved statistically significant and used elite college athletes.
To help answer your question: Time to onset of Lactate Threshold can make a significant difference because it clearly shows and improved efficiency in the metabolism of lactate. Just a few seconds of delaying onset of threshold can significantly increase an athletes pace and or ‘kick’ for the end of a race. For cortisol numbers were tested on collegiate cross country runners and found to be 30% greater than the general population. Allowing this cortisol to be 26% lower than the control group clearly showed Optygen’s ability to modulate stress which in turn allow athletes not only to remain healthier, but also to get more out of each training session.
