🔥 GRAND RE-OPENING CASTLE ROCK PERK ALERT: WEEK 2 🔥
This one’s a big deal. For a limited time, score 20% OFF hormone labs - that’s $30–$50 in savings toward feeling like you again.

Hormones run the show. They’re your body’s chemical messengers, controlling everything from energy and mood to metabolism, sleep, and muscle recovery. When levels are off, your body lets you know - and ignoring it can lead to bigger issues down the road.

✨ Feel better. Move better. Live better. ✨
Now’s the perfect time to check in on your hormones and take control of your health—for less.

It's Meet the Team Monday! Meet Abby B, RN! Here are some fun facts from Abby:
I am originally from Virginia and have lived in Denver for a decade.
Outside of work you can find me backpacking, snowboarding or traveling.
I actually love solo traveling and have visited four countries in this past year!
I don’t have any pets but I am an Auntie to the best golden retriever, Jackson :) My new favorite hobby is scuba diving and I will now travel to destinations for diving this year!
My favorite treatment at Qnus is the alpen glow. It's the perfect blend of beauty and immunity!

It's Meet the Team Monday! Meet one of our founders and chief marketing officer, Chaz! In his true fun-loving fashion, Chaz decided to share two truths and a lie for his fun facts:

1: Born in Denver, raised in Saudi Arabia 🇸🇦
2: Ranked in the Top 100 Tetris Players in the US when I was 9
3: I’ve had a Mohawk since 7th grade
My favorite treatment at Onus is BHRT(bioidentical hormone replacement)! It’s changed my life and I love hearing how many lives it changes for the better :)
