Testobolin is an anabolic and androgenic steroid. The main active substance is testosterone undecanoate. The form of release – injections, packing 4х1 ml, on 250 mg / ml. Testosterone undecanoate is characterized by prolonged exposure (due to the long side chain of the ester).
Testosterone is the main male sex hormone secreted by Leydig cells and the adrenal cortex (in women – by the ovaries). By its nature, it is a product of peripheral metabolism. Testobolin is often used by athletes who want to reduce the frequency of injections, while maintaining the hormonal background at a consistently high level. The biological activity of testosterone is low, it weakly binds to androgen receptors and is actually a prohormone. Before acting on the androgen receptors of the organs, it under the action of the enzyme 5-alpha-reductase is converted into dihydrotestosterone.
How to take Testobolin
Undecanoate lasts longer than other esters of testosterone. But, despite this, to maintain the hormonal background, it is recommended to inject at least once a week. Dosage varies from 250 to 500 milligrams. The main purpose of taking a steroid is a set of muscle mass. The course Testobolin solo gives excellent results, and its combination with other AAS is caused not so much by the need to increase the effects, but in minimizing possible “pobochek”. The duration of the course varies from 6 to 10 weeks. Blocking the estrogenic effect is made by taking Tamoxifen, and even better – Proviron. The latter can be used on the course, and upon its completion switch to Tamoxifen. When the duration of taking Testobolin XR is more than 4 weeks, it is advisable to use gonadotropin.
As for how to take Testobolin in combination with other anabolic and androgenic steroids, the best assistant is Nandrolone. In this case, the total weekly dosage should not exceed the norm for solo intake.
