Euro-Pharmacies Nandrolone Phenylpropionate 15 ml vial (75 mg/ml)

Nandrolone Phenylpropionate

Nandrolone phenylpropionate represents an injectable anabolic steroid, closely resembling Deca-Durabolin, which contains the slower-acting nandrolone decanoate. The key distinction lies in the rate of nandrolone release—while nandrolone decanoate remains effective for about three weeks, nandrolone phenylpropionate has a shorter active life of roughly one week, necessitating more frequent injections. Athletes and bodybuilders appreciate both for enhancing strength and lean muscle growth with minimal estrogenic or androgenic effects.

Structural Characteristics

Nandrolone phenylpropionate is a modified nandrolone form featuring a propionic phenyl ester attached to the 17-beta hydroxyl group. This esterification reduces polarity and slows absorption from the injection site. Once in circulation, the ester dissociates, unleashing active nandrolone. This design extends therapeutic effects and allows less frequent dosing compared to unesterified steroids, with nandrolone phenylpropionate delivering a quick release of nandrolone within 24 to 48 hours, tapering off within a week.

Side Effects (Estrogenic)

Nandrolone exhibits a low conversion rate to estrogen—approximately 20% of testosterone’s rate. Although the liver can convert nandrolone into estradiol, its conversion in adipose tissue is notably reduced. As a result, estrogenic side effects such as water retention, fat gain, or gynecomastia are less common but may occur at higher doses, possibly requiring anti-estrogens like clomiphene or tamoxifen. Users might also consider aromatase inhibitors like Arimidex (anastrozole) for more effective estrogen management, albeit at a higher cost.

Side Effects (Progestin Activity)

It’s important to note that nandrolone possesses progestin properties, potentially leading to similarities in side effects to estrogen, including testosterone suppression and increased fat storage. The combination of progestins and estrogens can elevate gynecomastia risk, thus suggesting the use of anti-estrogens to mitigate this issue.

Side Effects (Androgenic)

While primarily an anabolic steroid, nandrolone may still induce androgenic side effects like oily skin, acne, and hair growth at elevated doses. Women should monitor for virilization symptoms, which could manifest as voice changes or menstrual irregularities. Compared to more androgenic steroids like testosterone, nandrolone’s androgenic effects are typically milder, yet caution is advised to avoid libido suppression in men when not combined with an androgen.

Side Effects (Hepatotoxicity)

Due to not being c-17 alpha alkylated, nandrolone is unlikely to cause hepatotoxicity in healthy individuals.

Side Effects (Cardiovascular)

Anabolic steroids can negatively impact cholesterol levels, reducing HDL while increasing LDL, heightening arteriosclerosis risk. Dose, administration route, and steroid type will influence lipids, with studies showing nandrolone decanoate leading to significant HDL reductions. Cardiovascular risks include elevated blood pressure and potential myocardial infarction.

Side Effects (Testosterone Suppression)

All anabolic steroids suppress endogenous testosterone with sufficient doses. Research indicates a 57% testosterone level reduction with 100mg/week nandrolone decanoate, escalating to 70% at 300mg/week. The progestational effects of nandrolone may exacerbate this suppression, with testosterone recovery generally occurring within 2 to 6 months post-therapy.

Administration (Men)

For basic anabolic benefits, the recommended dosage is 25 to 50mg weekly for 12 weeks. Performance enhancement typically requires 200 to 400mg per week, split across two injections due to the rapid ester activity.

Administration (Women)

For women, initial guidelines suggest 25 to 50mg weekly for 12 weeks. For physique enhancement, common practice includes administering 50mg once weekly over 4 to 6 weeks. Care is needed due to potential androgenic side effects, and if they arise, immediate cessation is advised to prevent lasting changes.
