Billings providers order functional medicine compounds from Promise Pharmacy as a licensed nonresident 503A, not as a local retail counter. Billings is a mid-size city of about 120,864 residents in Yellowstone County (U.S. Census Bureau, Vintage 2023 population estimates). Compounds leave Palm Harbor under 21 U.S.C. § 353a and usually arrive in 3–5 business days.
Service area — shipping, not a storefront
If you practice in Billings, the honest version of this page is simple: we compound functional medicine compounds in Palm Harbor, we are licensed to ship into Montana, and we will not pretend a USPS tracking number is a local pharmacist down the street.
Billings (120,864 in Yellowstone County, U.S. Census Bureau, Vintage 2023 population estimates) loses winter days to weather. An unattended porch is a worse destination than a staffed suite when the compound is temperature-sensitive. Typical transit is 3–5 business days.
We do not operate a compounding bench in Billings. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific functional medicine compounds for Billings are prepared there, then shipped to the clinic or the patient named on the prescription. If you need a walk-in window on Yellowstone County streets, we are the wrong vendor — and we would rather say that than pretend otherwise.
Every tested batch has a Certificate of Analysis in the provider portal. If a Billings medical director wants the COA on file before the first patient injection, that is a normal request, not a special favor.
Billings is in Yellowstone County. We print that on this page because national pharmacy templates love to say “Greater Montana.” Greater Montana is not an address.
Amy Patel, RPh, our COO, has more than 25 years in sterile compounding. Clinical questions from Billings accounts go to the same compounding team — not a city-specific pharmacist we invented for this URL.
Standard compounding time is five business days. After that, Billings should plan on 3–5 business days in transit. If your protocol cannot survive that clock, say so on the onboarding call — expedite exists, magic does not.
Montana permits licensed nonresident pharmacies to ship compounded prescriptions and has a growing telehealth infrastructure serving rural communities. Verify a pharmacy license on the Montana Board of Pharmacy site rather than trusting a marketing page, including this one.
Montana has broad telehealth prescribing parity compared with many states, which is why video-first functional, integrative, and longevity clinics in Billings are a normal account type for us. Controlled substances are still federal: testosterone remains Schedule III, and Ryan Haight is not waived by a friendly state telehealth statute. For the underlying 503A vs 503B split, we keep a longer explainer on 503A vs 503B compounding rather than restating it on every city URL.

How this actually differs
This is a shipping 503A relationship with a Florida pharmacy — not a Billings storefront comparison.
| Promise Pharmacy (503A) | Commercial / retail | |
|---|---|---|
| Where it is made | Palm Harbor, FL compounding bench | Factory + wholesaler |
| What is being filled | Patient-specific 503A compound | Manufacturer stock bottle |
| Ship-to | Clinic or patient in Billings | Retail counter or mail-order PBM rules |
| Quality documentation | Third-party testing; COA in the portal | Manufacturer CoA, not yours to pull per patient |
| Billings transit & packaging | From Palm Harbor; typical 3–5 business days; insulated when the compound needs it | Local pickup or a chain that may not compound this Rx |
| Dosing | Written to the prescription, including custom strengths | Fixed commercial SKUs |
