What is Opalite Health Medical Group?
Opalite Health Medical Group is a medical wellness practice at 301 Alamo Dr, Suite H, in Vacaville, California. It offers five services: weight management, hormone replacement, peptide therapy, IV hydration, and a nurse concierge service for care at home after some outpatient surgeries or hospital stays. The weight management program names semaglutide (GLP-1) and tirzepatide (GIP/GLP-1), and it also offers an oral GLP-1 pill taken once a day. Hormone care covers testosterone, HCG, enclomiphene, clomiphene, estrogen and progesterone. The peptide menu includes BPC-157, TB-500, sermorelin and several others.
Dr. Derek Witteman, DO, is the physician and medical director. Jennifer Crow, DNP, RN, is the founder and is also listed as a prescriber.
Weight management starts with an in-house consultation, then lab draws if needed. If you are eligible, medication is sent home with you in a personalized medication case. The clinic is open by appointment only, Monday through Sunday, with no specific hours listed. It has a 5-star rating from 16 Google reviews.
What does it cost?
The clinic does not publish prices for weight management, hormone replacement or peptide care. Its IV hydration page refers readers to a pricing menu instead of listing prices. It does not state a consultation fee, whether medication is included in any price, whether it accepts insurance, or whether it offers memberships or financing. Ask for each of these before you book.
What should you ask before you book?
Ask who writes each prescription. Ask whether Dr. Witteman or Jennifer Crow will see you before any medication is prescribed.
Ask whether any monthly price includes the medication. Ask what the consultation, follow-up check-ins and lab work cost separately, since the weight management page says labs are drawn "if needed."
Ask whether each medication is brand-name or compounded. The clinic's website says: "We use FDA-approved 503a/b compounding pharmacies that produce consistent, quality-controlled medications." Ask which pharmacy fills each prescription.
Ask the same about peptides: which pharmacy supplies each one, and whether it is FDA-approved. Ask what research supports the specific peptide you are considering.
Ask whether any visits can be done by telehealth, whether it takes insurance or HSA cards, and how to cancel a program or membership. Ask whether you pay for months you do not use.
Who is it a good fit for?
This is a good fit if you want cash-pay access to a practice with a physician and a nurse prescriber under one roof, and you are willing to get prices and medication terms in writing before you commit. It may not suit you if you need prices posted online before you call, or if you need telehealth visits.
