Testoviron is a mixed testosterone injectable, containing varying amounts of testosterone propinate and testosterone enanthate. The faster acting propinate ester is included to support testosterone release during the early days of therapy, while the longer acting ester is included to support the latter part of the theraputic window. Together, the two are supposed to result in a rapid increase in testosterone level, followed by a sustained hormone elevation for approximately 2 weeks. The design of this steroid is therefore very similar to Sustanon, although lacking the decanoate ester will remain active in the body for a shorter duration. Testoviron was originally marketed as an improvement over single ester preparations like testosterone enenthate, said to provide a much more balanced release of hormone in comparison.
Upon close analysis, the pharmacokinetic properties of Testoviron are not as ideal as initially described. The problem lies in the fact that testosterone enanthate is not a delayed onset drug, but actually provides a sharp spike in testosterone levels 24-48 hours after administration. Adding a fast activg ester like tesotserone propinate to a formulation of testoerone enanthate only compounds the initial testosterone spike. A study administering a blend of 115.7mg of testosterone enanthate and 20mg of testosterone propinate confirms this tendency; demonstrating maximal increases in testosterone the first day following injection.
History
Testoviron was developed by international pharmaceutical giant Schering in Germany and marketed tat one time in many of the European markets including Ger4many, Austria, Italy, Spain, Ireland, Greece, Switzerland, Netherlands, Denmark, and Sweden. This product is, likewise, usually identified as a European item, although produced scarcely in Eastern Europe and the Caribbean as well.
The Schering Testoviron products first surfaced in Europe during the early 1950's and have since been duplicated in one form or another by numerous different drug manufacturers in many parts of the world. Although scarcely remembered, blended enanthate and propionate products were once even available commercially in the US. Most notable was the brand Testoject E.P. from Mayrand, which contained 200mg of testosterone enanthate and 25mg of propionate in a 1ml vial. Today however, no such commercial product exists. Blended ester products like this are still prescribed in the US, but lack of a commercial item means they are only dispensed by the private compounding pharmacies.
Sherign/Bayer has been fining its steroid product line a great deal since the 1990's eliminating many unprofitable or controversial items. This has resulted in their discontinuing the sale of blended ester Testoviron compounds in most markets. The only known product left on the European market is Testoviron Depot 100, which contains 110mg of testosterone enanthate and 25mg of testosterone proprionate for a 100 mg total dose of (free) testosterone. As mentioned earlier, blended testosterone enanthate and proprionate products are produced by many other companies, and can still be located in a wide variety of human and veterinary drug markets.
Availability
Schering (now Bayer) has discontinued manufacture of its blended Testoviron product in most parts of the world. Testoprim-D from Mexico is one of the most commonly located products. This item comes in a light resistant ampule that is packaged in a red box bearing white print. The writing is printed directly on the glass surface of the ampule. The ink used is a whte /grayish color that does not smear with a good thumb rub.
Aratest from Aranda (Mexico) appears to still be circulating. This product comes in a 10ml multidose vial.
Bi Testo is made by Cimol in Argentina. This product comes in a multidose vial. There are no security features to deter counterfeiting, although copies are not known to be a problem.
