Testimonials

Wilson Chandler, Denver Nuggets

I think it's the best thing for athletes...especially playing here in the altitude, Hydration is a big part of recovery for us. I think, with Onus IV Hydration, just getting those back, gettings those IVs, and adding certain things back, glutathione, amino acids, stuff that's essential to your body in recovery. And then bypassing your gut - going straight into your blood stream - it's the fastest way possible to get it.

After returning from an international trip that required 35 hours of flight time and not having much sleep for 50 hours, I was mentally and physically exhausted. I received an immunity iv drip. Immediately, I had energy and alertness, which helped me power through my day and think clearly. Onus is a secret offset to jet lag.

This was my first time doing IV Therapy and Onus IV was amazing! Jason was extremely helpful and made me feel very comfortable. I would highly recommend checking them out!

Derrick McBride

Onus is my go to anytime I'm trying to fight off or prevent an illness. The first time I got the immunity drip I had a brutal sore throat that WENT AWAY during the drip. I was sold from then on. These services have been huge for traveling and flu season. Just got another yesterday!

Eva K.

Wow!! Blown away by the customer service, relaxed environment and efficiency of Onus! My bf had been feeling under the weather so we came to get him some hydration. The guy giving the IV, I'm sorry i forgot your name, he was so knowledgeable, patient and kind! Didn't fish for a vein. Very professional and painless. The manager was also working and she was equally amazing. They ensure you're comfortable with blankets, drinks and entertainment. I would recommend onus 1000x over other hydration bars in Denver. Thanks guys!
