For BHRT and integrative practices in Billings, Promise Pharmacy compounds lab-guided bioidentical estradiol, progesterone, testosterone, DHEA, pregnenolone, BiEst, and TriEst on a patient-specific prescription, then ships from Palm Harbor, Florida. Billings is a mid-size city of about 120,864 residents in Yellowstone County (U.S. Census Bureau, Vintage 2023 population estimates). Fulfillment target is five business days in the pharmacy, plus 3–5 business days in transit.
Service area — shipping, not a storefront
Billings is a mid-size city of about 120,864 residents in Yellowstone County (U.S. Census Bureau, Vintage 2023 population estimates). We support practices in Billings with clinic delivery and direct-to-patient shipping.
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.
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.
Montana has broad telehealth prescribing parity compared with many states, which is why video-first BHRT and integrative practices in Billings are a normal account type for us. Controlled substances are still federal: testosterone remains Schedule III, and state telehealth laws do not waive Ryan Haight requirements. For the underlying 503A vs 503B split, we keep a longer explainer on 503A vs 503B compounding.
Standard compounding time is five business days. After that, Billings should plan on 3–5 business days in transit. Discuss any expedited requirements during your onboarding call.
Credentialing is not a formality. We check an active Montana-recognized prescribing license (MD, DO, NP, PA, or equivalent) before the account orders BHRT compounds. Testosterone and other controlled substances also need DEA registration.
A mid-size market like Billings needs reliable repeat fills. We support repeat prescriptions for BHRT compounds with portal ordering, a named account manager, and five-day compounding.
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.
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.

Clinic or patient address. Typical transit 3–5 business days. Refrigerated compounds go insulated.

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