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 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 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 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 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 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 is one of the most popular anabolic steroids for gaining muscle mass. In addition, it should be added that nandrolone practically does not cause a rollback phenomenon.
SIDE EFFECTS:
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.
FOREIGN PROFILE:
Half-life: 2-4 days.
Duration of action:10-15 days.
Frequency of intake:2 times a week.
Hepatotoxic rate: low.
Detection time:More than 8 months*
*- approximate drug concentrations at various dosages.
Phenylpropionate is a medium-acting ester. The usual frequency of intake is 2 times a week, the peak decreases quickly, but the residues leave the bloodstream slowly.
It is said that Nandrolone Phenylpropionate can be used during the cutting cycle, but since it is the same drug and the ester has an insignificant effect on the properties of the Nandrolone molecule, so the use of Nandrolone Phenylpropionate is limited to bulk only . Only gain, mass and recovery cycles.
