- Active Ingredient: Nandrolone Decanoate
- Type: Anabolic Steroid (19-nortestosterone derivative)
- Form: Injectable
Nandrolone, also known as 19-nortestosterone, is an anabolic steroid that can be naturally produced in the human body during intense physical activity or pregnancy. Its main metabolite, 19-norandrosterone, is found in urine but in very low concentrations.
Structurally, nandrolone is similar to progestins due to the absence of a carbon atom in the 19th position. This difference from testosterone results in significantly less androgenic effects. However, the stabilization of progesterone receptors can cause unique side effects.
Unlike testosterone, nandrolone does not convert to the powerful androgen dihydrotestosterone (DHT) via the 5-alpha reductase enzyme. Instead, it converts to an extremely weak androgen called dihydronandrolone. This makes nandrolone a suitable choice for male athletes with prostate problems.
Nandrolone has a relatively low risk of side effects. Due to its low androgenic activity, issues such as acne, baldness, and body hair growth are rare. However, as with any steroid, these side effects are possible if recommended doses are exceeded.
Nandrolone has approximately 6 times less estrogen conversion compared to testosterone. It does not aromatize in the liver, and the primary site of conversion, adipose tissue, is inaccessible. As a result, nandrolone has minimal estrogen-related side effects such as gynecomastia and fluid retention, which occur only at high doses.
Due to its ability to promote muscle mass gain and minimal risk of rollback phenomenon, nandrolone is highly popular among anabolic steroid users.
- Pronounced muscle growth with minimal rollback phenomenon
- Improved bone and ligament strength
- Enhanced skin regeneration and collagen synthesis
- Relief from joint pain through increased synovial fluid production
- Increased red blood cell mass, leading to improved oxygen transport and endurance
- Boosted immune system (recommended for AIDS patients)
- Conversion to estradiol without aromatase enzyme involvement
- Improved absorption of amino acids and nutrients in the intestines
- Nandrolone can bind to progestin receptors, leading to increased prolactin production and suppression of gonadotropic hormones. This can cause a decrease in testosterone production, slight fat gain, and, in rare cases, gynecomastia.
- Possible side effects include increased blood pressure, abdominal pain, irritability, headaches, and depression.
- Less common side effects may include headache, back pain, and gynecomastia.
- For joint pain relief and bone strengthening in elderly patients, a dosage of 50-150 mg per week for 5-10 weeks is recommended.
- For muscle mass gain, a dosage of 200-800 mg per week is common. The average dosage is 400 mg of nandrolone combined with 500 mg of testosterone per week.
- Half-life: 7-9 days
- Frequency of administration: Once a week
Nandrolone decanoate has a long duration of action and is suitable for extended mass-gaining cycles. The typical duration of a nandrolone cycle is 8-10 weeks, but some athletes may use it for up to six months, gradually increasing the dosage. For amateurs, it is advisable not to exceed an 8-week cycle without additional drugs. Chorionic gonadotropin (hCG) is recommended for longer cycles. If hCG is not used during the cycle, it should be administered before post-cycle therapy (PCT) and not during PCT itself.
Nandrolone decanoate injections are typically administered once a week. Since its activity period is 15 days, there is no need for multiple weekly injections unless the total weekly volume is large. Testosterone should be used concurrently with nandrolone to prevent progestin-related effects and low testosterone consequences (low libido, weak erection, depression).
