We do everything in our power to make sure that THRIIV is 100% safe for everyone. We have gone through every related scientific study related to our formulation multiple times, created molecular biological models, tested the purity of every ingredient, laboratory tested our final product and in vivo tested the final product numerous times to ensure safety. We have not had even one mild incident occur and we plan to keep it that way. If for any reason you feel that THRIIV is unsafe, then please contact us, and hopefully we can address your concern. Even if it means redeveloping our product. We are open to doing anything that promotes safety with the use of our products.
