The main active substance of the pharma is nandrolone decanoate, which belongs to classical steroids. The substance is a derivative of testosterone with increased anabolic activity and decreased androgenic activity.
In the section of the structure, the steroid differs from testosterone in that there is no carbon atom at position 19. This makes it similar to progestins and decreases the androgenic effect, but reacts with progesterone receptors. Testosterone gradually turns into estrogens, which does not happen with nandrolone decanoate. Anabolic activity is 150% of testosterone, and androgenic activity is 30%. It is minimally susceptible to aromatization and has almost no effect on the liver. The half-life is about 7 days. The substance is active for 15 days, and on doping control it can be detected within 18 months. This fact is very important, because the drug is not suitable for those who are preparing for the approaching competitions.
The course of nandrolone decanoate solo
The effect of the drug unfolds slowly enough. Do not expect a rapid anabolic effect. But at the same time, almost all the accumulated indicators are preserved even after steroid withdrawal. The course of solo nandrolone decanoate, as a rule, is long. Weight gain is approximately half that of testosterone. The recommended course duration is from 8 to 10 weeks. In some cases, athletes take it for up to six months, with a gradual increase in dosage. Injections are performed no more than once a week in a volume of 200 to 600 milligrams.
Side effects of nandrolone decanoate:
Nandrolone inhibits the production of testosterone by the body. This is due to the fact that the long-lived metabolites of nandrolone also have progestogenic activity, and the nandrolone itself is in the body for an extremely long time. The deca binds to progestin receptors, and therefore such reactions as suppression of the secretion of gonadotropic hormones, increased production of prolactin are not ruled out. Due to the moderate androgenic nature and the ability to suppress endogenous testosterone, nandrolone can influence libido reduction if Testosterone is not used simultaneously.
At the same time, problems associated with aromatization, this steroid is almost not typical, the risk of gynecomastia and excess water accumulation accompanies only the intake of high doses (over 400 mg per week).
