⚠️ Note: Tirzepatide & Semaglutide can only be compounded for patients with a documented medical necessity — such as an allergy to an inactive ingredient or need for an alternative formulation. Diagnosis alone (e.g. weight loss, type 2 diabetes) and cost are not valid reasons under FDA 503A.

Required by your pharmacy under FDA 503A. The Rx must document this reason — the pharmacy will reject a generic or diagnosis-only justification.

⚠️ We can no longer fulfill compounded Natural Desiccated Thyroid (NDT) requests. The FDA is taking enforcement action against unapproved animal-derived thyroid products, and US compounding pharmacies are no longer filling NDT prescriptions. FDA-approved alternatives — Armour Thyroid, NP Thyroid, and WP Thyroid — remain available at retail pharmacies with a prescription. See alternatives →
Enter the per-fill amount the pharmacy will dispense each time — match what's written on your prescription if you have one. Example: an Rx for 60 capsules with 2 refills = enter 60, not 180.
