Testobolin XR is an anabolic and androgenic steroid from the Indian pharmaceutical company Alpha Pharma. 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. TrenRapid 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 influence of the enzyme 5-alpha-reductase is converted into dihydrotestosterone.
