Testoviron 250 by Schering

Testoviron 250 is an injectable steroid made by Schering, its active substance is Testosterone Enanthate.
Testosterone Enanthate is probably the most commonly used form of testosterone by both athletes and bodybuilders alike.
Testoviron 250 is an oil based injectable steroid, which is designed to slowly release testosterone from the injection site. This slow release delivery leads to an elevation in testosterone levels lasting for approximately two weeks (it may even take as long as three weeks for the drug levels to fully diminish). Due to its relatively long activity level, Testosterone Enanthate is favored by the medical profession and is primarily used to treat cases of hypogonadism and similar disorders where low androgen levels are at fault. As with all testosterone products it has strong anabolic and androgenic activity. Gains in strength and muscle mass are notable, along with an increase in libido. It has also been noted that a relief in tendon pain and an increase in stamina are direct effects of Testoviron 250 administration. This is probably due to increased water retention coupled with an increase in red blood cells – leading to a greater oxygen uptake in the blood.
Testosterone is a highly anabolic and androgenic hormone, it has an anabolic (muscle building) as well as anabolic rating of 100 each, respectively. Testoviron 250 exerts the majority of its effects by promoting increased nitrogen retention in the muscle. Testoviron 250 is also known to increases levels of the growth factor IGF-1 in both the muscle tissue as well as the liver. This steroid also increases the activity of satellite cells, which are cells that play an active role in repairing exercise-damaged muscle.Testoviron 250 exerts these effects primarily by genomic mechanisms, meaning that it binds to the androgen receptor (AR) thus initiating gene transcription. This stimulation of the AR promotes various of the AR dependant mechanisms for both muscle gain and fat loss, as well as reducing catabolic glucocorticoid hormones, and increasing red blood cell production.

HOW DOES IT WORKS?

Weekly totals of 250-1000mg weekly are frequently used, and sometimes more for the highly advanced athlete. Due to the relatively long half life of Testoviron 250 (4-5 days), injections are usually administered twice per week. This will allow stable blood levels to be maintained. When the level of steroid tapers down, a new injection is made, keeping everything fairly level. This is unlike Sustanon, which requires more frequent injections for the same effect. For a first cycle, 500 mg alone of Testoviron 250, shot two times weekly (Monday and Thursday for example), for 10 weeks along with standard post cycle therapy would be very sufficient for good gains.
As the best mass builder available, Testoviron 250 stacks well virtually everything and can also be used alone with high levels of success. Due to the longer half life of Testoviron 250, a dose of 500 mg per week can be used for the first time user for a period of 10 weeks with very good results. Stacking oral steroids on a first cycle is generally considered uneccessary, because it is impossible to gauge your body's responsiveness to the individual steroids being used and determine which ones cause which side effects. For the more advanced athlete, doses of 500 - 1000 mg of Testoviron 250 are also excellent for creating clear results within a 10 week period. More advanced athletes will often stack Testosterone Enanthate with Dianabol, Deca Durabolin, Primobolan or Equipose to create a powerful mass building stack.
All testosterones aromatize, and enanthate is no exception. The steroid user should be familiar with anti-estrogen compounds such as Nolvadex and Clomid and keep them on hand during cycle in case symptoms of gyno arise. Increases in water weight and fat weight should be expected, and the possibilities of gyno are always out there when usingTestoviron 250.
Standard post cycle therapy consisting of either Nolvadex or Clomid should take place after the cycle is over.

SIDE EFFECTS:

Side effects such as water retention usually occur when using Testosterone Enanthate. Gyno, increased rate of hair growth, back acne, increased blood pressure, and aggressiveness, both in the gym and out, are possible when using this steroid. The liver is accustomed to processing testosterone, so liver toxicity is normally not a concern except at extremely high doses.
