Trenbolone is basically a derivative of nandrolone with some very significant differences in their chemical properties and strength. Trenbolone and its parental hormone nandrolone belong to the category of anabolic steroids known as 19-nor compound, or 19-NORS (short for 19-nortestosterone).As the 19-nor anabolic steroids are called steroids lacking the 19 carbon in their structure, in all other anabolic steroids, including testosterone, this carbon is not missing. This will significantly change the characteristics of an anabolic steroid. This lack of carbon 19 is what makes the 19-nor compound highly resistant to the enzyme aromatase. Such modifications are also responsible for the great strength of the androgen (binding to the androgen receptor), and its ability to remain highly resistant to the metabolic break-down in the body.
Those who use it report that its effects on strength development are fully comparable with such means as oxymetholone, methandienone, testosterone, or even more powerful. The peculiarity of trenbolone acetate is also that it increases the metabolism of fat, while even in the bulking preparation it's possible with its 'help' to build big, strong and hard muscles at the same time.
As it happens, each extremely effective substance abused by athletes is also characterized by extremely negative effects on the body. The veterinary trenbolone acetate is no exception. In the foreign literature is mentioned the high harmfulness to the kidneys - particularly in longer-term application or at higher doses. Classic manifestation of his "action" is a strong blood coloured urine and pain in the kidney.
When using Trenbolone, it should be recognized that the "hard" and a unique side effects result from the fact that it is a 19-nor progestational compound. Studies have shown that 19-nor anabolic steroids tend to exhibit a binding affinity for the progesterone receptors in the body. Trenbolone has notably very strong binding affinity (much stronger than nandrolone) for progesterone receptor. Progestogen side effects are almost identical to estrogenic side effects, and these include: severe suppression of endogenous production of testosterone, gynecomastia and water retention (which is not the case with Trenbolone).It was found that the activity of progestogens is closely related to the activity of estrogen in the body.
Of course there are also problems of androgenic nature - acne, headaches, and supposedly enormous aggression and high blood pressure that can be increased because the composition does not cause retention of water and salt.
