Testosterone enanthate is currently the most popular ester of testosterone available to athletes. Unlike cypionate, enanthate is manufactured by various companies all over the world. Ampules of Testoviron from Schering are probably the most popular although many others exist. Enanthate is a long acting testosterone similar to cypionate. Injections are taken once weekly, with a dosage of 200-600mg being most common for athletes. Testosterone Enanthate has very strong anabolic effects as well as strong androgenic side effects. Gynocomastia and water retention are the most common side effects and should be watched for. Being an injectable testosterone, liver values are generally not elevated much by this product.
