This protocol, inspired by Phil Campbell’s Interval Training Model, stimulates HGH and EPO utilizing simultaneous hypoxia and hypoglycemia, separated by hyperoxia. The training method rapidly improves VO2 max beyond other known training methods.
EPO Phase: The model utilizes different stress models to stimulate adaptive mechanisms. EPO is stimulated by initial and repeated hypoxia.

ExtremeO2 increases respiratory challenge during high intensity training. Campbells group documented over a 500% increase in HGH levels with sprint‑8 protocols.
HGH Phase: Sprinting under hypoxic conditions creates a strong anaerobic burst, which drives strong hypoxia and rapidly consumes serum glucose causing a hypoglycemic dip. This dip stimulates HGH levels.
There are three main differences in this protocol from the traditional sprint‑8 model based on:
- The detox effect entends recovery time between sprints — especially early ones. You can gauge toxin mobilization by recovery delay before the next sprint.
- Recover but don’t rest. Once you recover from your previous sprint — do another;
- Stop when your sustainable sprint duration reaches half. The number of sprints you complete up to eight illustrates your progress.
- This protocol allows for “fuller” recovery between sprints to allow for detoxification. Start your sprints immediately after you recover. Don’t rest while your in the sprint phase.
- Adipose tissue is largely non-vascularized. The cycle appears to stimulate fat-loss when followed by systemic hyperthermia. When a sauna or hottub is available the author notes an average weight loss of 1/2 lb per session — when combined with moderate calorie restriction.
Escalated Detox occurs when blood flow and pulse exceed typical exertion levels. This tends to create considerable detoxification — especially in early cycles.

We have one of your VO2 Max machines at BioDentist in Denver Colorado. Is there a link or is there a product manual available to instruct us on how to use this? Or is there a link online with a video of some sort? We purchased this machine and have no way of knowing how to use it. Your help in getting this up and running would be most appreciated.
Thank you …
