Testomastren 400 by Isis pharmaceuticals is a powerful testosterone blend ( Testosterone Enanthate 200mg, Trenbolone Enanthate 100 mg, Masteron Enanthate 100 mg ). It is created to maximise positive effects and gains while reducing the down sides of each.
Testomastren 400 is a strong blend of testosterones which in some users can convert to dihydrotestosterone which is a worry for some as this can cause male pattern baldness but again this can be controlled by use of Finasteride and Regain. In order to achieve such a high concentration of steroid it appears that the amount of alcohol used in the solution has been markedly increased. Without increasing the alcohol level 400 milligrams of steroid would simply be too much for the solution to dissolve. The steroid hormone is more soluble in an oily solution with heightened amounts of alcohol, which allows us to achieve a dosage otherwise not possible.
Testomastren 400 is a blended product with each milliliter containing 25 milligrams of testosterone propionate, 187 milligrams of testosterone cypionate and 188 milligrams of testosterone enanthate. Denkall's Testomastren 400 is the absolute highest concentration for any steroid in one milliliter of oil.
Users commonly report strong irritation and pain at the site of injection due to that the alcohol makes for an irritating, almost caustic solution to inject. Thus in many instances requiring the user to dilute the steroid with lower dosed oil based products if Testomastren 400 is to be continued. Testomastren 400 looks like an instant winner for those solely interested in maximum dosage, or those willing to later dilute a steroid in order to purchase the most steroid in single vial possible.
