Testoviron is a mixture of Testosterone Enanthate and Testosterone Propionate. In a way it is similar to sustanon as Propionate will kick in quickly and enanthate will keep working for 2 – 3 weeks. The usual dose is, as with all testosterones, 200 – 400 mg per week.

Testoviron is just like all other testosterones: gives good strenght and mass gains and at the same time also has noticeable side effects.


Testoviron is a mixed testosterone injectable (propionate/enanthate), produced by the firm Schering in many parts of the world. Since Schering also uses the Testoviron brand name to market pure testosterone enanthate, one should not confuse all such items with this mixed preparation. In fact most preparations found circulating with this brand name are actually the enanthates, which are vastly more popular among athletes. When locating the Testoviron blends, we notice they are prepared in a number of different strengths. All will contain a base of testosterone enanthate, with a lesser amount of testosterone propionate added in. Being much faster acting, the propionate gives us a quick effect while the enanthate is slowly reaching circulation. The result is an injectable that will increase the testosterone level very quickly; yet sustain an elevation for approximately two to three weeks. The design of this steroid is therefore similar to that of the testosterone blend Sustanon, although Testoviron will remain active in the body for a noticeably shorter duration.

This steroid is clearly not an unusual compound, as it would obviously have an effect similar to other blended testosterone products such as Sten and Sustanon. One can expect to see a rapid buildup of strength and muscle mass during a cycle of this drug, as is to be expected with all injectable testosterones. This will likely go hand in hand with a noticeable level of water retention, as testosterone converts into estrogen quite readily. A loss of muscle definition is likely to result, as subcutaneous water and fat stores reduce the visibility of muscle features. For this reason Testoviron is not the ideal item for cutting phases of training. The added estrogen level may also cause the development of gynecomastia. In order to reduce this possibility, sensitive individuals may need to add an antiestrogen like Nolvadex and/or Proviron during each cycle. Testosterone preparations will also suppress endogenous androgen levels, so a stimulating drug like HCG and/or Clomid/Nolvadex may be needed to avoid a post-cycle crash. Since this effect is particularly pronounced with testosterone, a combination of both drugs may prove to be the most useful in many cases.

Testosterone also converts to the more potent steroid DHT (dihydrotestosterone) in many areas of the body, a process that is responsible for the strong androgenic activity of this hormone. Testoviron is therefore likely to produce a number of unwanted androgenic side effects, including oily skin, acne, body/facial hair growth and male pattern hair loss. Those who have an existing male-pattern hair loss condition, or believe they may be prone to this problem, may wish to stay away from testosterone products for this reason. Strong androgens can easily aggravate cases of hair loss, a side effect of steroid use that is pretty much irreversible once noted. Others may simply opt to include a daily dosage of Proscar/Propecia, which will greatly reduce the buildup of DHT and lighten the androgenic nature of testosterone. We must remember however, that while Proscar offers us help, it is no assurance this side effect will not develop during a cycle all androgenic effects are mediated by the same receptor as anabolic. Deca-Durabolin would still be a much safer choice in this regard however.

Testoviron is clearly an acceptable alternative to standard testosterone preparations. These ampules are not commonly found on the black market, but are certainly a good choice if located. Here in the U.S., Testoprim-D ampules are the most likely to show up. This is not a counterfeit item as other steroid references may list, but is in fact a legitimately manufactured Mexican pharmaceutical. Counterfeits of this item have never been located, so Testoprim will probably remain to be a safe buy for some time. When looking for this item in Mexico, we see a single light resistant ampule that is packaged in a white and red box, bearing black print. With the ampule, we also note that the writing is printed directly on the glass surface. The ink used is a white/grayish color that does not smear with a good thumb rub. By the time this item is found in the United States, these boxes have usually been discarded (the ampules are easier to smuggle loose). Aratest from Mexico has also been circulating, and is the only version of this mix to come in a multi-dosed vial at this time. Early unconfirmed reports have been that it is a markedly under dosed product however, so be careful. The only fake to note in this section is actually a different but similar testosterone propionate/undecanoate blend bearing the company name Octagon, avoid.
