Harder Ingredients and How They Work

Harder was developed by our co-founding urologists, Dr. Joshua Gonzalez and Dr. Brian Steixner, to target blood flow, erectile strength, and longer-lasting performance. Every ingredient was selected to complement your Volume + Taste routine and take your results further.

Take 2 capsules daily with water alongside your Volume + Taste. Harder is designed to be paired with Volume + Taste and is not intended as a standalone supplement. Hydration and consistency are key. This is a daily supplement, and results improve over time with regular use.
