We’re a modern men's health company revolutionizing preventative care

Vault is a men's health company focused on letting men get back to the things they love doing.

1 in 3 men don’t have a doctor and most will only go to one if they think something is seriously wrong. We’re focusing on solving a big problem rarely talked about and infrequently diagnosed: low testosterone.

“Vault is giving patients access to the transformative benefits of testosterone replacement therapy.”

Dr. John P. Mulhall

We've worked with the best medical minds to create treatment plans for hard-working men like you

As men get older, we gradually lose our ability to produce testosterone. But that's not the end of the story. Our medical advisors have spent thousands of hours developing clinical care pathways to diagnose and treat testosterone deficiency. The result is the Vault platform: safe, effective, and unlike anything else in men's health.
