Supporting Studies

Why we're different...

We’re THE LAB. We’re scientists and nutrition experts. We do the research ourselves, do the experimenting ourselves, and formulate the products ourselves. We’re the guys who the other guys hire to make their products. We’ve been formulating supplements for decades so no one knows more about supplement science than we do. And no other brand focusses on emerging science and cutting edge ingredients like THE LAB does.

Real results

Energy Level through the roof....

At 43 years old I decided it was time to go back to the gym and get healthy again. I chose to try The Labs T-Sterone capsules knowing that men my age tend to have lower levels of testosterone. Within a few days of taken these capsules my energy level was threw the roof. These capsules made it easy to get back into an active lifestyle. I no longer feel sluggish and tired halfway through the day. - Chris G.

Girlfriend noticed a change...

While taking The LAB's T-Sterone Capsules I noticed an immense amount of energy throughout my work day. No more 2pm crashes. My workouts have been way more intense, and YES, even my girlfriend noticed a change. I LOVE THIS PRODUCT! - John B
