Euro-Pharmacies Nandrolone Phenylpropionate 10 amps (10x 100 mg/ml) EXPIRATION

Nandrolon Fenylpropionaat

Nandrolone phenylpropionate is an injectable anabolic steroid similar to Deca-Durabolin. The key distinction lies in their release rates: nandrolone decanoate sustains release for around 3 weeks, while nandrolone phenylpropionate acts within a week. Clinically, Deca-Durabolin is administered every 2–3 weeks, contrasted with Durabolin, typically given every few days to weekly. Both steroids are largely interchangeable, and athletes admire them for promoting strength and lean muscle gains with minimal estrogenic or androgenic side effects.

Structurele kenmerken

Nandrolone decanoate features a modified structure where a propionic phenyl ester attaches to the 17-beta hydroxyl group. Esterified steroids are absorbed more slowly than free steroids, thus allowing for a sustained therapeutic effect and reduced injection frequency. After deep intramuscular injection, nandrolone phenylpropionate typically releases a significant amount of nandrolone within 24–48 hours, tapering off in about a week.

Bijwerkingen (oestrogeen)

Nandrolone’s estrogen conversion is relatively low at around 20% of testosterone. While the liver can convert nandrolone to estradiol, its lower affinity in adipose tissues lessens estrogenic concerns. Higher doses may still increase estrogen levels, leading to side effects like water retention and gynecomastia. Preventive measures include anti-estrogens such as clomiphene citrate or tamoxifen citrate, or aromatase inhibitors like Arimidex (anastrozole) to curb estrogen synthesis, albeit at a higher cost.

Side Effects (Progestin)

Nandrolone exhibits progestin activity, possibly affecting testosterone production and fat storage. This synergy could lead to gynecomastia even with minimal estrogen. An anti-estrogen may mitigate this side effect associated with nandrolone.

Bijwerkingen (Androgene)

Despite being classified as anabolic, nandrolone can produce androgenic side effects, especially at elevated doses. Symptoms may include oily skin, acne, and body hair growth. Women should be cautious of virilization symptoms like voice deepening and clitoral enlargement. With relatively low androgenic activity, users face a higher threshold for such effects compared to more potent steroids like testosterone. Notably, nandrolone can suppress libido in males if not combined with other androgens.

Bijwerkingen (hepatotoxiciteit)

Nandrolone is not c-17 alpha alkylated, indicating a low risk of hepatic toxicity in healthy individuals.

Bijwerkingen (cardiovasculair)

Anabolic steroids can negatively affect serum cholesterol, decreasing HDL and increasing LDL levels, raising arteriosclerosis risk. A study of nandrolone decanoate showed a 26% reduction in HDL levels, slightly worse than testosterone enanthate, yet better than c-17 alpha alkylated agents. Other cardiovascular risks include increased blood pressure and potential left ventricular hypertrophy.

Bijwerkingen (Testosteron onderdrukking)

All anabolic steroids, including nandrolone, can inhibit natural testosterone production. Research indicates that doses around 100mg weekly can reduce testosterone levels significantly. The progestational mechanisms of nandrolone contribute to this suppression, which can last 2–6 months after cessation, necessitating medical intervention in prolonged cases of hypogonadism.

Administratie (Mannen)

For anabolic effects, initial guidelines suggest 25–50mg weekly for up to 12 weeks. Performance enhancement typically involves 200–400mg weekly, in cycles of 8-12 weeks, with doses split into 2 applications due to the rapid action of its ester.

Administration (Women)

Women often follow similar general recommendations of 25–50mg weekly for 12 weeks. For performance enhancement, a single weekly injection of 50mg for 4–6 weeks is common. Due to potential androgenic effects, higher doses should be avoided, with immediate discontinuation advised if virilization occurs, to prevent long-lasting changes.
