1.Deceptive Subscription and Billing Practices: ZenSulin is often sold through confusing checkout pages promoting bulk bundles and “limited-time” offers. Many users report unexpected recurring charges after their initial order, with cancellation terms hidden in fine print, making it difficult to stop unauthorized repeat billing.

5.Unverified and Questionable Ingredients: ZenSulin promotes common blood sugar-regulating ingredients, such as cinnamon and bitter melon, but lacks transparency about ingredient dosages, sourcing, and third-party lab verification. Consumers cannot confirm the product's purity or effectiveness.
6.No Independent Testing or Clinical Evidence: There are no peer-reviewed clinical trials supporting ZenSulin’s claims for blood sugar regulation. It is not FDA-approved and lacks independent lab testing, leaving its safety and effectiveness unproven.
