To answer your question about where the medications come from we use both Signature Pharmacy in Orlando and Central Drugs in California. Really though the raw materials that both pharmacies use to make the medications come from the same company called Medisca. Medisca is the largest supplier of the raw product Somatropin and other powders. If you need any more information regarding any of this we do have letters both from Medisca stating they supply these pharmacies with the raw product powders and then Cert of Analys. from Analytical Research Labs on the testings of the final products.
