The short version. This is an independent OlyLife distributor site, not OlyLife itself, and we earn income when you buy through it. The products are general wellness devices, not medical devices. Nothing here is medical advice or a promise of any health result. The lab reports we publish confirm the device is electrically safe and measure the energy it emits; they do not measure any health benefit.
01Independent distributor & material connection
thzupgrade.com is owned and operated by David Gantner, doing business as THzEssentials (referred to here as "we," "us," or "THz Upgrade"), an independent authorized distributor of OlyLife products. This site is not OlyLife's official website. It is not operated, sponsored, endorsed, or controlled by OlyLife, and the views and statements on it are ours, not OlyLife's.
Because we are an independent distributor, we have a financial relationship with the products on this site that you should know about: we earn income when you purchase through this site. When you click a "Buy Now" button, you are buying from us as the seller, and we benefit from that sale. We tell you this so you can weigh our enthusiasm accordingly. We have done our best to describe these devices honestly and to separate what is proven from what is still being studied.
"OlyLife," "Tera-P90," "Galaxy G-One," and related names are the property of their respective owners. We use them only to identify the products we sell.
02Health & wellness disclaimer
OlyLife products are marketed as general wellness devices, not medical devices. They are intended to support everyday comfort, relaxation, and a general sense of wellbeing.
These statements have not been evaluated by the U.S. Food and Drug Administration. These products are not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition. Nothing on this site should be taken as a claim that any device will treat or affect any specific health condition.
The information on this site is provided for general educational purposes only and is not medical advice. It is not a substitute for the advice of a qualified physician or other licensed healthcare provider. Always seek the advice of your physician with any questions you have about a medical condition or before starting any new wellness routine. Never disregard professional medical advice or delay seeking it because of something you read here.
Check with your physician before use if you are pregnant or nursing, have a pacemaker or any other implanted or wearable electronic medical device, have epilepsy or a seizure disorder, have metal implants, are being treated for any medical condition, or have any concern about whether these products are appropriate for you. If you feel unwell during use, stop and consult a healthcare provider.
Individual experiences differ from person to person. Any experience described on this site is personal to the individual who reported it and is not a representation of what you or anyone else will experience.
03Testimonials & reviews
Any testimonials, reviews, or customer comments on this site reflect the real, individual experiences of the people who provided them. They are shared because they are genuine, not because they are typical.
Results are not typical and are not guaranteed. What one person experiences with a device is not a promise, prediction, or guarantee of what you will experience. Testimonials describe personal wellness experiences only; they are not medical claims and should not be read as evidence that any device treats, cures, or prevents anything.
We do not pay for or condition any testimonial on it being positive. If a person who provides a testimonial has a connection to us that a reader would want to know about, for example, if they are a distributor, a friend, a family member, or received any incentive, that connection is disclosed alongside their comment. We do not publish invented testimonials, and we do not edit reviews to hide unfavorable feedback.
04Product claims, science & lab testing
We try to be precise about what the evidence actually shows, and to keep separate lanes separate. Two different things are easy to confuse, so here is the distinction we hold to:
What the lab reports confirm
Independent, third-party testing has been performed on these devices. Electrical safety and electromagnetic compatibility have been tested by an accredited testing laboratory (Intertek). Separately, the terahertz-band energy a device emits has been independently measured by a testing laboratory under defined test conditions. We are happy to provide the relevant reports on request.
What those reports do not confirm
These reports verify two things only: that the device meets recognized electrical-safety and electromagnetic-compatibility standards, and the characteristics of the energy it emits as measured in a laboratory. They are not measurements of any health benefit, therapeutic effect, or clinical outcome. An emission measurement describes what a device puts out; it says nothing, on its own, about what that does for the body. Where a measurement was performed, it is specific to the particular unit and model that was tested.
How to read terms we use
To avoid any confusion, a few words mean exactly what they say and nothing more. "Registered" with a regulator is not the same as "cleared" or "approved" by that regulator. A "granted patent" is not the same as a "pending" application. "Independently measured" refers to the energy the device emits, not to any proven health effect. PEMF is a technology category that has been studied for decades; references to that research describe the general field and are not claims about these specific devices.
05No professional advice & outside links
Nothing on this site is medical, legal, financial, or other professional advice. For advice specific to your situation, consult the appropriate licensed professional.
This site may link to or embed third-party content, such as videos hosted on Vimeo or pages on other websites. We do not control that content and are not responsible for it. A link or embed is not an endorsement, and we make no representations about the accuracy of anything found through it.
06No guarantee of results
We make no guarantee that you will experience any particular outcome from using these products. Wellness experiences depend on many personal factors that are outside our control and outside any device's control. Any descriptions of how a session "feels," or how often people use a device, are general and individual, not assurances of a result for you.
