Compounded medication sourcing for functional medicine practices
Functional medicine practices order many small, formulation-specific products, so prices, shipping times and backorders vary across a long list of pharmacies and portals. AffinityRx is the multi-pharmacy marketplace that fixes this: synthetic thyroid (T3/T4), LDN, nutrient injectables and hormones from 15+ vetted pharmacies in one login, about 10% savings versus the practice's current price, 1–5 day shipping and failover within 1–2 minutes.

What functional medicine practices typically order
Functional medicine practices typically order the compounded categories below through AffinityRx, and each links to its medication page.
- Desiccated thyroid: FDA regulatory explainer; not orderable on AffinityRx
- Liothyronine: compounded and sustained-release strengths where a prescriber documents the need
- Levothyroxine: compounded strengths
- Naltrexone (LDN): low-dose capsules and other forms
- Methylcobalamin: injectable
- NAD+ and glutathione: injectables
- Progesterone and estradiol: hormone programs
Availability, strengths and price vary by pharmacy, and the live AffinityRx catalog is the source of truth. AffinityRx does not make clinical claims about any medication and does not choose a medication, dose or directions for a prescriber.
Sourcing problems for functional medicine practices and how AffinityRx addresses them
AffinityRx fixes the six sourcing pains functional medicine practices raise most, ranked by how often they close deals: unoptimized prices, slow shipping, backorders, multiple pharmacy portals or APIs, 50-state coverage and getting started. See the best compounding pharmacy marketplaces for how AffinityRx compares.
Thyroid formulations that do not match across pharmacies
The problem. Synthetic liothyronine and levothyroxine strengths and fillers differ, and a practice that titrates by lab values needs the formulation to stay put.
How AffinityRx addresses it. The AffinityRx catalog lists each pharmacy's strengths and dosage forms so staff keep a patient on one formulation, and AffinityRx does not substitute a different dose.
Small-batch orders in many categories
The problem. A practice may order ten different products a month in low quantity, which is expensive to manage through separate portals.
How AffinityRx addresses it. One AffinityRx account covers the 15+ pharmacies, and AffinityRx pharmacy comparison shows price for each product.
Lab-driven changes that interrupt refills
The problem. When a lab result changes a protocol, the next order changes too, and the old pharmacy's portal does not reflect it.
How AffinityRx addresses it. Staff prepare a new order against the current catalog, and the prescriber signs it. AffinityRx order tracking shows what is in flight.
Non-sterile and sterile quality evidence
The problem. Capsules and injectables sit under different standards, and a practice should see both sets of evidence.
How AffinityRx addresses it. AffinityRx compliance vetting displays USP 795, 797 and 800 status, COAs, sterility and endotoxin testing and accreditations per pharmacy.
Prescriber credentials across a care team
The problem. Practices have physicians, nurse practitioners and physician assistants, and each needs the right access.
How AffinityRx addresses it. Prescriber profiles and licenses and team roles are managed in the Clinic app. See billing and credits for who sees invoices.
503A, 503B, office-use and state licensure for functional medicine practices
AffinityRx orders are prescriber-signed and patient-specific today (the 503A model). Office-use and clinic-stock ordering are not available yet; they arrive with 503B outsourcing facilities in Q4 2026–Q1 2027.
Functional medicine practices write patient-specific prescriptions that 503A pharmacies fill, and each compounded preparation should be tied to a documented patient need. State licensure applies to both the pharmacy and the prescriber, and AffinityRx checks pharmacy eligibility against the shipping state. Office-use supply is not available yet; it arrives with 503B outsourcing facilities in Q4 2026–Q1 2027.
