What is Testosterone enanthate?
Testosterone enanthate is a depot formulation that releases testosterone over time. Products, injection route and schedules differ across markets.
Approved-use context
Licensed products are used for testosterone replacement when deficiency has been established through clinical and laboratory assessment. Some products have additional narrowly defined indications.
How it works
The ester is hydrolysed to testosterone after administration. Resulting testosterone acts at androgen receptors throughout the body.
Formulations and schedules
Testosterone enanthate is commonly supplied as an oil-based injection. Some products use intramuscular administration while specific devices may have different authorised routes.
