Hormone Replacement
Fixed commercial HRT doses that do not match the labs sitting on the desk — that’s why Billings clinics call. We compound HRT compounds patient-by-patient and ship from Florida.

Billings providers order HRT 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
Providers in Billings can discuss patient-specific strengths, dosage forms, and availability for HRT compounds with our compounding team.
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 compounds for Billings are prepared there, then shipped to the clinic or the patient named on the prescription. Local walk-in service and pickup are not available in Billings.
Credentialing is not a formality. We check an active Montana-recognized prescribing license (MD, DO, NP, PA, or equivalent) before the account orders HRT compounds. Testosterone and other controlled substances also need DEA registration.
Billings is in Yellowstone County. We ship patient-specific compounds to clinics and patients in Billings.
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.
Amy Patel, RPh, our COO, has more than 25 years in sterile compounding. Clinical questions from Billings accounts go to our compounding team in Palm Harbor.
USP chapters 795, 797, and 800 are the compounding standards we work to. Chapter 797 addresses sterile compounding, and Chapter 800 addresses hazardous drug handling. The Montana Board of Pharmacy can tell you how Montana expects a nonresident pharmacy to document that.
Federal compounding authority for what we do is 503A of the FD&C Act (21 U.S.C. § 353a): a licensed pharmacy, a patient-specific prescription, USP compounding standards. State permission to land the package in Billings sits with the Montana Board of Pharmacy.
How this actually differs
This is a shipping 503A relationship with a Florida pharmacy — not a Billings storefront comparison.
| Promise Pharmacy (503A) | Commercial / retail | |
|---|---|---|
| Ship-to | Clinic or patient in Billings | Retail counter or mail-order PBM rules |
| Account model | Credentialed provider account + named manager | Retail profile or PBM network |
| Dosing | Written to the prescription, including custom strengths | Fixed commercial SKUs |
| Where it is made | Palm Harbor, FL compounding bench | Factory + wholesaler |
| What is being filled | Patient-specific 503A compound | Manufacturer stock bottle |
| 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 |

Montana compounding
These are separate programs on the same 503A account — still shipped from Palm Harbor, still not a Billings storefront.
