After more than a year of exhaustive diligence on multiple Thyroid manufacturers, we are excited to have selected and entered into a partnership with SP Labs as their only US distributor of Thyroid USP for compounding pharmacies.  We have been very careful to select a manufacturer that meets our best-in-class quality standards and passes our stringent supplier qualification requirements.  We are thrilled to bring Thyroid, USP back to our customers from a source Letco and our customers can trust.

NOW AVAILABLE: Thyroid, USP (Porcine). Manufactured in the United States, extensive supplier qualification process, third-party audited manufacturing facility, and complete testing for each lot received.
