The testosterone medication Delatestryl (testosterone enanthate) is available in both brand-name and generic form. Paddock Laboratories and Watson Pharmaceuticals are two of the companies that make a generic version. Although these formulations are considered equivalent to the brand-name product, they are allowed to contain different inactive ingredients, which may lead to problems in people with certain sensitivities.
Delatestryl® (testosterone enanthate) is a prescription medication approved for the treatment of low testosterone in men. It is also approved for use in women with certain types of breast cancer. The drug is injected into a muscle once or twice a month.
Brand-name Delatestryl is made by Sandoz Canada, Inc., for Endo Pharmaceuticals Solutions, Inc. However, it is also available in generic form. Generic Delatestryl is one of the most affordable testosterone replacement medications available.
Generic Delatestryl is available in one strength: Testosterone enanthate 200 mg per mL (in 5-mL vials). It is made by a few different companies, including Paddock Laboratories and Watson Pharmaceuticals, Inc.
All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns a rating to each one.
An "AO" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic versions of testosterone enanthate currently available have an "AO" rating, meaning they should be equivalent to Delatestryl.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
