Testomastren 400 Isis contains 200mg Testosterone Enanthate, 100mg Trenbolone Enanthate, 100mg Masteron Enanthate, 2% Benzyl Alcohol, 20% Benzyl Benzoate and Ethyl Oleate. The effects of Testomastren 400 would be similar to that of all testosterones. Testomastren 400 is the ultimate testosterone mass builder and is usually stacked on a bulking phase with the likes of Deca Durabolin and Dianbol or Anadrol 50. The Dianabol or Anadrol 50 should be used in the first 4-6 weeks of the cycle to kick start the whole process by up regulating the receptor sites, the Testomastren 400 and Deca Durabolin would be continued for the full 8-12 weeks. Testomastren 400 is very highly anabolic and very highly androgenic and will cause a massive increase in strength and size which you will physically see in approximately 14-16 days. Testomastren 400 is very popular amongst bodybuilders today and I have physically seen it produce dramatic results for competitive bodybuilders whilst in early stages of preparing for competition. Testosterone is one of the best mass-building agents. It is also strongly estrogenic and androgenic. This includes water retention, possible fat increases and even gynecomastia is estrogenic levels get too high, and acne, oily skin and possible hair loss from the androgenic component of this steroid. These side effects can be minimized with ancillary drugs such as anti-estrogens like Nolvadex, Clomid or Arimidex, and/or the 5-alpha reductase inhibitor Proscar. Testomastren 400 is readily aromatized into estrogen like most other Testosterone based Steroids. It has been shown to increase Sex drive, Aggression and libido.
