What is Norethandrolone?
Norethandrolone (Nilevar) is a steroid with anabolic properties primarily used for muscle growth and strength gains. Developed in the 1950s, this compound delivers strong anabolic effects along with androgenic properties, making it attractive to athletes aiming to increase muscle mass. However, its popularity has decreased over time, and its use is now limited.

General Information
Effects on Muscle Development and Performance
Muscle Growth: Norethandrolone helps in increasing muscle mass. Since it has a high anabolic effect, it promotes the development of muscle tissue by increasing protein synthesis.
Nitrogen Retention: It supports muscle building and prevents muscle loss by positively affecting the nitrogen balance in the body.
Strength Gain: May improve athletic performance by providing higher energy levels during training.
Side Effects
Estrogenic Effects: Norethandrolone does not aromatize so it does not directly convert to estrogen, but due to its progesterone-like effects it can lead to side effects such as gynecomastia or water retention.
Liver Toxicity: As an oral steroid, it can have toxic effects on the liver. Prolonged and high-dose use can cause liver damage.
Androgenic Side Effects: Androgenic side effects such as acne, oily skin, and hair loss may occur. In women, side effects such as male-pattern hair growth (hirsutism) may occur.
Recommendations for Use and Dosages
Beginner Level
Weekly dosage: 25-50 mg per week, usually used for 4-6 weeks.
Since it is taken orally, daily doses can be divided into 5-10 mg. It is recommended to start with this low dose for the beginner level.
Intermediate Level
Weekly dosage: 50-75 mg, usually for 6-8 weeks.
For intermediate users, it can be divided into 10-15 mg daily doses.
Advanced Level
Weekly dosage: 75-100 mg, 8 weeks course for maximum effect.
Advanced users can go up to 20 mg per day, but with higher doses, regular checks for liver health are important.
Pharmacological Details
Half-Life: Approximately 8-10 hours.
Duration of stay in the body: 1-2 days.
Elimination Time: It may take 2-4 days to be completely eliminated from the body, but the exact elimination time varies according to individual metabolic rates.
Combination Suggestions
Norethandrolone can be combined with other anabolic steroids for more effective results:
Testosterone Enanthate or Cypionate: Increases energy and strength while promoting muscle mass gain. This combination is popular during the bulking phase.
Primobolan (Methenolone): It is preferred to increase muscle hardness and endurance. When combined with Norethandrolone, it contributes to the formation of hard and dense muscle mass.
Oxandrolone (Anavar): Provides more defined muscle growth by minimizing water retention. It can be a good combination, especially for those looking to gain lean muscle mass.
Duration of Use and Side Effects
It is recommended that Norethandrolone not be used for more than 8 weeks in order not to increase the risk of toxicity in the liver. In addition, it is important to adjust the other steroids used in the combination according to the same cycle duration in order to reduce the burden on the liver.
