What is Injecting Confidence?
Injecting Confidence is a medical spa at 8310 South Valley Highway, Suite 100, in Centennial, CO 80112, and it opened in 2018. Katie Guest, BSN, RN, founded the practice and is the only prescriber it names. Most of what it does is aesthetic: injectables such as Botox and dermal fillers, laser treatments, facials and medical-grade skincare. Its wellness side covers weight loss, hormone therapy, peptide therapy and longevity testing, plus Vitamin IV Therapy, ShapeScale Body Analysis and a New Patient Consultation.
Its weight loss service uses two GLP-1 medications, Semaglutide and Tirzepatide, and starts with a consultation, then a treatment plan, a guided start and regular check-ins. Hormone Replacement Therapy sits under its hormone optimization services, and Cellular Aging + Longevity Testing falls under longevity medicine. Peptide Therapy is listed as a service, but no description is published. It names Greenwood Village, Englewood, Littleton, Parker and Aurora as areas it serves, though Centennial is the only office address. Hours are Monday to Friday, 09:00 am to 06:00 pm, with Saturdays by appointment.
What does it cost?
It does not publish prices for any service, including weight loss, hormone therapy, peptide therapy or longevity testing, and it does not list a consultation fee. It does not say whether medication is included in any price, whether it accepts insurance, whether telehealth visits are offered, or whether memberships and commitment terms apply. Get every figure and term in writing before you book.
What should you ask before you book?
Start with the prescriber. In its own words: "Every treatment plan is overseen by our medical team." Ask who that team includes, whether a physician reviews or signs each prescription, and whether Katie Guest, BSN, RN, writes them herself.
Next, ask whether a monthly or per-visit fee covers Semaglutide or Tirzepatide, and whether either is the brand-name product or a compounded version. If it is compounded, ask which pharmacy makes it. Ask what the consultation, follow-up visits and lab work cost, since its weight loss and hormone services describe testing and regular monitoring without a price. Ask what peptide therapy is, what it treats and who prescribes it. Finally, ask whether HSA cards or financing are accepted and how you cancel.
Who is it a good fit for?
This is a good fit if you want a medical spa that handles aesthetic care alongside prescription weight loss or hormone therapy, and you are willing to get prices, prescriber names and cancellation terms in writing before you pay. It is a weaker fit if you need published prices or a clear explanation of peptide therapy before you call.
