Profile & Medical use
Nandrolone (chemical name – 19-nortestosterone) – an anabolic steroid can be formed in the human body after intense or prolonged physical exertion or during pregnancy, the concentration of its main metabolite 19-norandrosterone in the urine , but in very low concentrations.
Structurally, nandrolone decanoate differs from testosterone due to the absence of a carbon atom in the 19th position (hence the name 19-nortestosterone) and this makes it more similar to progestins. Due to its progestin origin, nandrolone displays a significantly lower androgenic effect than testosterone, however, the stabilization of progesterone receptors causes unique side effects.
Another difference is that, unlike testosterone, this is converted by the enzyme 5-alpha reductase into a powerful androgen – dihydrotestosterone, which is responsible for the development of most side effects. In contrast, nandrolone decanoate is converted by 5-alpha reductase into an extremely weak androgen – dihydronandrolone.
EFFECTS:
Pronounced muscle growth (in one cycle you can gain up to 8 kg of muscle mass with minimal rollback phenomenon).
Strengthens bones (used to treat osteoporosis) and ligaments, improves skin regeneration, stimulates overall collagen synthesis.
Elimination of joint pain by increasing the production of synovial fluid (joint lubrication).
Increased red blood cell mass, which causes better oxygen transport. The result is better breathing in the cellar and greater resistance.
Strengthening of the immune system (recommended for AIDS patients).
Conversion to estradiol without aromatase enzyme.
Improve intestinal absorption of amino acids and other nutrients.
A good choice for male athletes with prostate problems.
Nandrolone decanoate has a relatively low chance of side effects. Due to the low androgenic activity, there are practically no side effects such as acne, baldness and body hair growth. However, they are possible, as with the use of any steroid, but in the case of nandrolone this only happens when the recommended doses are exceeded several times.
Nandrolone decanoate has a 6 times lower level of conversion to estrogen than testosterone (this occurs without aromatase). The highest conversion rate is observed in the liver, while the main conversion site (adipose tissue) remains inaccessible to this process. As a result, nandrolone decanoate has no estrogen-related side effects (gynecomastia, accumulation of fluid in the body). The estrogenic activity of the drug appears only at very high doses.
This explains why nandrolone decanoate is one of the most popular anabolic steroids for gaining muscle mass. In addition, it should be added that nandrolone decanoate practically does not cause a rollback phenomenon.
NANDROLONE HAS BEEN ASSOCIATED WITH THE FOLLOWING SIDE EFFECTS:
It has been noticed that nandrolone is able to bind to progestin receptors (about 20% of the introduced substance), this is due to the removed carbon atom at position 19. All 19-nor anabolic steroids exhibit progestin activity.
By binding to progestin receptors in the pituitary gland, nandrolone causes an increase in prolactin production and suppresses the secretion of gonadotropic hormones. Prolactin acts similarly to estrogen in the brain, its effect is manifested by a decrease in the production of its own testosterone. In the body it causes a slight increase in fat and, in rare cases, gynecomastia.
also, during increased blood pressure, abdominal pain, irritability, headache, depression are possible.
RARE:
Headache,
Back pain,
gynecomastia.
DOSAGE:
To eliminate joint pain and strengthen bones in elderly patients, use 50-150 mg per week for 5-10 weeks.
To increase muscle mass use 200-800 mg per week. The average dosage is 400 mg of nandrolone per week, combined with 500 mg of testosterone.
DECANOATE FOREIGN PROFILE:
Half-life: 7-9 days.
Duration of action: 14-16 days.
Frequency of intake: once a week.
Detection time: more than 10 months*
*- approximate drug concentrations at various dosages.
Decanoate has a long-lasting effect and its use is justified for long courses of mass gain. The nandrolone cycle usually lasts 8-10 weeks, while it is not uncommon for sports athletes to use it for up to six months, gradually increasing the dosage.
If you are an amateur, do not take a course for more than 8 weeks without additional medications. For long courses, the use of chorionic gonadotropin is recommended. If hCG has not been used for a long course, it is necessary to take it at the end of the course before the PCT, but not at the PCT itself.
Nandrolone decanoate injections are usually administered once a week. Considering the period of activity – 15 days, it is not necessary to take 2 injections per week. But if the weekly volume of injected drugs is large, it is often split into two or three injections.
Nandrolone cycle with mandatory use of testosterone is recommended to avoid progestin effects and consequences of low testosterone level (low libido, weak erection, depression).
