Nandrolone Phenylpropionate injection by Genesis

• Effective substance: nandrolone phenylpropionate,
• Content: 100mg/ml
• Vial with: 10ml
• Known as: NPP

Nandrolone (19-nortestosterone) is an anabolic steroid. The positive effects of the drug include muscle growth, appetite stimulation and increased red blood cell production and bone density. Clinical studies have shown it to be effective in treating anaemia, osteoporosis and some forms of neoplasia including breast cancer, and also acts as a progestin-based contraceptive. The substance Nandrolone phenylpropionate quickly gets into the blood, where it remains active for two to three days. Patients who hope for optimal results inject Nandrolone Phenylpropionate every third day, or even every two days. The dosage is around 50-100 mg per injection, or a total of 150-300 mg/week.

Nandrolone Phenylpropionate (NPP), often associated with the brand Genesis, is a fast-acting anabolic steroid used both in clinical medicine and performance enhancement.

Unlike the more common Nandrolone Decanoate (Deca-Durabolin), which has a long ester and stays in the system for weeks, the Phenylpropionate ester acts much faster, requiring more frequent injections but leaving the body more quickly once discontinued.

Product Description & Characteristics

• Formulation: Typically provided as an oil-based solution for intramuscular injection (often 100 mg/mL).
• Anabolic/Androgenic Ratio: It has a high anabolic rating with relatively low androgenic activity, making it popular for muscle growth with fewer "harsh" side effects compared to testosterone.
• Active Half-life: Approximately 2.5 to 3 days. This means it reaches peak blood levels quickly and requires injections every 2-3 days to maintain stable levels.

 Common Uses

1. Medical: Historically used to treat anemia, breast cancer, and osteoporosis. It is also utilized to prevent muscle wasting in patients with chronic illnesses.
2. Performance: Used by athletes for lean muscle mass gains, improved recovery, and joint relief (due to increased water retention in connective tissues).

 Side Effects & Risks

Because NPP is an 19-nortestosterone (19-nor) derivative, it carries specific risks:

• Natural Hormone Suppression: It significantly suppresses natural testosterone production. Post-Cycle Therapy (PCT) is generally required after use.
• Estrogenic Effects: While it aromatizes at a lower rate than testosterone, it can still cause water retention and gynecomastia (breast tissue development in men).
• Progestogenic Activity: It can increase prolactin levels, which may lead to side effects like "Deca Dick" (erectile dysfunction).
• Virilization: In women, it can cause irreversible male traits such as deepening of the voice, body hair growth, and clitoral enlargement.
• Cardiovascular Strain: It can negatively impact cholesterol (HDL/LDL) levels and increase blood pressure.

 Dosage Guidelines

Medical dosages are determined strictly by a healthcare provider. In non-medical contexts, users often follow these patterns:

• Men: Typically 200–400 mg per week, split into injections every other day or every third day.
• Women: Much lower doses (e.g., 25–50 mg per week) to minimize the risk of virilization.
