Thermozen 90-Day Money-Back Guarantee

Take Thermozen consistently for 90 days. If you don't feel a meaningful difference in your hot flashes and night sweats, contact us at hello@vonolabs.com for a full refund.

You do not need to return the bottles. You do not need to fill out a form. You will not be asked to prove you tried it. No interrogation. No return shipping.

We offer this guarantee because we have seen what happens when women finally get the right dose targeting the right signal. We are not worried about the guarantee. We are worried about the women who need this and talked themselves out of trying.

To request a refund, email hello@vonolabs.com within 90 days of your purchase date with your order number. That's it.

For all other returns (wrong item shipped, damaged product, etc.) please contact us within 7 days of delivery.
