"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.”
