Active ingredient: Nandrolone Decanoate

Type: Anabolic steroid (19-nortestosterone derivative)

Form: Injection

Carrier oil: Sesame oil

Nandrolone Decanoate is an anabolic steroid derived from 19-nortestosterone, commonly used in the form of injections. It is worth noting that Nandrolone is a chemical precursor to 19-norandrosterone, a metabolite found in urine at low concentrations after intense physical activity or during pregnancy.

Structurally, Nandrolone differs from testosterone due to the absence of a carbon atom in the 19th position, which gives it progestin-like properties. As a result, Nandrolone exhibits significantly less androgenic effects compared to testosterone. However, its interaction with progesterone receptors can lead to unique side effects.

Unlike testosterone, which converts into dihydrotestosterone (DHT) through the enzyme 5-alpha reductase, Nandrolone undergoes conversion into dihydronandrolone, an extremely weak androgen. This makes it a suitable choice for male athletes with prostate issues.

Nandrolone has a relatively low probability of side effects. Its low androgenic activity means that adverse effects such as acne, baldness, and excessive body hair growth are rare. However, it’s important to note that like any steroid, these side effects may occur when recommended doses are significantly exceeded.

Compared to testosterone, Nandrolone has approximately six times less estrogen conversion (without aromatase). The highest conversion occurs in the liver, while the main conversion site, adipose tissue, remains less accessible to this process. As a result, Nandrolone has minimal estrogen-related side effects such as gynecomastia or fluid retention. Estrogenic activity is only observed at very high doses.

These properties make Nandrolone one of the most popular anabolic steroids for gaining muscle mass. Additionally, Nandrolone is known for causing minimal muscle loss after a cycle.

Effects:

Promotes significant muscle growth with minimal muscle loss after a cycle
Strengthens bones, ligaments, and improves skin regeneration
Alleviates joint pain by increasing synovial fluid production
Enhances red blood cell mass, leading to improved oxygen transport and increased endurance
Boosts the immune system, beneficial for patients with AIDS
Converts to estradiol without the need for aromatase enzymes
Improves intestinal absorption of amino acids and nutrients

Side effects:

Binding to progestin receptors can cause an increase in prolactin production and suppression of gonadotropic hormone secretion, potentially leading to decreased testosterone levels, slight fat gain, and, in rare cases, gynecomastia
Possible side effects include increased blood pressure, abdominal pain, irritability, headaches, and depression
Rare side effects may include headache, back pain, and gynecomastia

Dosage:

To alleviate joint pain and strengthen bones, a dose of 50-150 mg per week for 5-10 weeks is recommended
To gain muscle mass, a dosage of 200-800 mg per week is common, with an average of 400 mg of Nandrolone combined with 500 mg of testosterone per week

Profile:

Half-life: 7-9 days
Frequency of intake: Once a week

Nandrolone decanoate is a long-acting ester suitable for extended mass-gaining cycles. Typical cycles last 8-10 weeks, although some experienced athletes may use it for up to six months, gradually increasing the dosage. For amateurs, it is not recommended to exceed 8 weeks without additional drugs. Long cycles should include the use of chorionic gonadotropin (hCG). If hCG was not used during the cycle, it is advisable to take it at the end of the cycle before beginning post-cycle therapy (PCT).

Nandrolone decanoate injections are typically administered once a week. Given its 15-day activity period, there is no need for twice-weekly injections. However, if the weekly volume of injected drugs is significant, it can be divided into two or three injections. Combining Nandrolone with testosterone is recommended to avoid progestin effects and the consequences of low testosterone, such as low libido, weak erection, and depression.
