Caught a bug the day before I was supposed to fly across the country. Decided to give Onus a try, and so glad I did. I had the immunity booster iv and it was a great blend of vitamins and zinc to battle the bug I was fighting. It made me feel much better the next day. This was my first time getting an iv, and I wasn't sure what I was in for, but the staff were incredibly friendly and they explained the entire process in detail. There was a little pinch at the beginning (which wasn't that bad) and then it was pain-free. The space--inside Denver Sports Recovery--is calm, comfortable and helps you chill. While I hope to not get sick again for a long time, I will certainly head back here if I do. I'd also like to look into their treatments for hangovers, and sports recovery. read more

My first visit to Onus iV was yesterday and there is no doubt I will be returning soon. In fact, this was my first hydration IV. I selected John Meyer (JMC) and the result was amazing. Usually, in the late afternoon into the dinner hour, I struggle to stay awake and alert. If I watch TV I can fall asleep in minutes. After the treatment yesterday I was awake, alert, feeling great, and watching TV without falling asleep. This was so easy to do, the staff are amazing, the environment is cool, the IV was painless, it was over in about 30 minutes. After one visit I am planning on being a regular customer. read more

I absolutely love this place! They have IVs that will fit anybody's needs.

The staff is wonderful and do a great job creating a relaxing environment, while you get your drip! Can't say enough good things about this place. read more

I tried Onus IV a few weeks back while on a trip to Denver with some girlfriends. Got a bit too wild the night before and was practically dying from the worst hangover of my life the next morning. I found out about Onus IV while at an event at Red Rocks that morning and was calling the minute I found out they opened. They immediately called me back and said they were about to open and to come on in. This was my first time trying IV hydration and did not know what to expect. EVERYONE on the staff was friendly, welcoming, and super informative! Although I did not feel better instantly as I hoped, once I went home and napped I felt like a new person upon waking. Would definitely recommend Onus IV to anyone in the same boat I was :) read more

Awesome place! friendly staff made my experience very comfortable, I will be back! Loved how I felt after my vitamin infusion

I just discovered how amazing this makes you feel when you're worn down. I highly recommend if you feel on the edge of getting sick, or need a boost before a big work week etc. I would also bring out of town friends here if they're having altitude issues. All around awesome!! read more

Chaz was welcoming, answered my questions, was receptive. Great experience. Highly recommend.

Def worth the 5 stars!! What a cool place!! Came in for some much needed hydration. They have such an array of options to help whatever ails you! The space is tucked up above the Denver Sports Recovery Center, but it will be transforming soon. Even so, the space is comfortable and chill. Not to mention everyone there is very educated, personable and fun! Truly a fun & beneficial experience! Will def continue coming here! Oh-- and I forgot-- they have a mobile service too! Def could have used that when I was pregnant! read more

Amazing! The kindest people helped me recover from likely the worst hangover of my life. Within a few hours of my IV, I felt better. I strongly recommend Onus to anyone for recovery or wellness. They are fantastic, and I really really want them to open up in Stapleton. read more

Worth every penny! I was battling a terrible case of the flu and was extremely dehydrated, to a point where I couldn't even get out of bed or open my eyes. Chaz and one of his nurses came to my house and we're nothing short of fantastic. They were both so kind and caring and after a short nap and IV fluids (immunity bag), I felt so much better! I could actually get out of bed, make some food for myself, and ate and drank with no problem! You guys saved me!! Will definitely be referring people to you and use you in the future. Thanks! read more

Such an amazing facility and the best selection of add ons with the most knowledgeable and friendly staff! I highly recommend Onus for all your iv hydration needs! read more

I absolutely love this place! I've been three times! I've been super sick this winter and this has definitely made a difference in hydration and helping me get well! The staff are all so friendly and do whatever is possible to make you comfortable!!! Very reasonable in cost and I'd highly recommend this to anyone! Sure beats a visit to the urgent care! read more

Super nice experience. It was my first time and I was not disappointed. I got the Phoenix IV after a night of parting and it sure helped tremendously with recovery ! Staff is knowledgeable and super friendly. Definitely recommend to anyone ! read more

This place has saved my life this past year! As a high school Principal, PhD student, and all around busy person, Onus gives me the vitamins and hydration I need to continue to maintain and perform. The staff is amazing, professional, kind and helpful. read more

Had a wonderful experience her I made a same day appointment and only had to wait a tiny bit . I got my own iv cocktail and got hooked up and out in about 20 minutes. Going back tomorrow read more

Amazing service! Thought I was getting sick and the immune booster really helped.

August, fire-medic, was AWESOME. Found my vein on the first try and kept me super comfortable. I got IV for an illness years ago and even some of the best nurses and docs struggled to stick my vein the first time! Thank you August! I love this place and will be back for sure! Feeling awesome and grateful for ONUS IV. read more

My mouth was constantly dry due to medications that cause dryness. I couldn't drink enough water, my doctor even gave me a prescription mouth rinse. Nothing worked. Then, I saw an article in YourHub that mentioned Onus iV and I thought it couldn't hurt to try. I went to the office in Greenwood Village where everyone was so nice. After some questions they fixed up an IV mix for me and put me in a comfortable chair. That next morning, my mouth wasn't dry anymore, my hair stopped falling out and I felt great. I will not hesitate to make regular visits to stay hydrated! Great staff! Thanks, Jeanne read more

These guys are amazing!!! I used Onus IV to prep before the SuperBowl... I was able to party pretty hard that weekend without any hangover. After the Broncos won the SuperBowl we couldn't stop partying. When I got back to Denver I used Onus IV again and they were able to put some life back into me. They were professional, curious and very knowledgable regarding what my needs were. I would highly recommend Onus IV! read more

Awesome staff here at Onus. Very knowledgeable and amazing environment, definitely 5 stars and would come back in a heartbeat.

Amazing how much Onus can help you breeze through jet lag, a tough work week and the holidays. This place is a must go if you aren't feeling 100% or need to be for race or ski trip read more

I was so miserably hungover, spent all day in bed. Called up Onus and they came and hooked me up and I feel a million times better. Well worth it and the staff are so friendly! read more

I was feeling under the weather and had an upcoming flight so I booked an session on their website which made it super easy. I loved the whole experience. You get to sit in comfy chairs, drink tea, and watch Netflix if you'd like. I'm sort of a scaredy-cat when it comes to needles but the insertions was completely painless. I got an Immunity IV. When I walked in I felt fatigued and shaky. When I left I felt SO MUCH better. I totally recommend adding a trip to Onus into your Wellness routine. Will definitely be back soon. P.S. They do house calls!! read more

Great service. Comfortable chairs. Offered tea which was nice, just a little pricey compared to other places I've gone.

Awesome experience at Onus iV. Came in for the immunity iv and feeling better already. Comfortable setting and super friendly staff. Highly recommend. read more

Vince & Josh were very entertaining & awesome! Highly recommend this place. Hungover, sick, or just dehydrated they make it all better!

Onus was set up at a race finish line and since I had a BIG race coming up I decided I'd try it. Usually after a high altitude ultra I have a hard time rehydrating and sleeping for a few days. I had the fastest and best recovery because of getting an IV. The low cost was worth it because I slept really well after my race and went on to have a stellar race 4 weeks later. I highly recommend Onus for a speedy recovery after any race. read more

This is the best recovery spot in Denver. Highly recommended. The team is extremely friendly and accommodating.

My husband was so sick he couldn't even get out of bed. Thankfully a team from Onus iV came to our house to get my husband hydrated and back on his feet. Great customer service, reasonable pricing and they were knowledgeable as well as helpful. Thank you Onus iV!!!!! Now we want to go check out the location for all of the other services. I highly recommend Onus iV for health prevention and care. read more

Kelly was great. I was a bit anxious, but she took the time to explain all the different options and benefits. Nice atmosphere and super friendly people. Even got a blanket when I got chilly! Highly recommend. read more
