Pharma Lab Nandrolone Phenylpropionate 10 amps (10x 100 mg/ml) EXPIRATION

Nandrolone Phenylpropionate

Nandrolone phenylpropionate is an injectable anabolic steroid derived from nandrolone. Similar to Deca-Durabolin, which utilizes nandrolone decanoate, the key distinction lies in the release speed— nandrolone phenylpropionate acts within a week, while nandrolone decanoate lasts approximately three weeks. In clinical settings, Deca-Durabolin is administered every 2-3 weeks, whereas Durabolin requires injections every few days to once a week. Both steroids are effectively interchangeable, valued by athletes and bodybuilders for enhancing strength and lean muscle gains with minimal estrogenic or androgenic side effects.

Structural Characteristics

Nandrolone phenylpropionate features a modified structure where propionic phenyl ester attaches to the 17-beta hydroxyl group. These esterified steroids exhibit slower absorption from the injection site, extending therapeutic effects and reducing injection frequency. Nandrolone phenylpropionate provides a swift release peak 24-48 hours post-injection, tapering off to baseline levels within a week.

Side Effects (Estrogenic)

Nandrolone converts to estrogen at a markedly lower rate than testosterone, with only 20% of conversion potential. While elevated estrogen levels may emerge with higher doses—causing water retention, fat gain, and gynecomastia—anti-estrogens like clomiphene citrate or tamoxifen citrate can mitigate these effects. Aromatase inhibitors such as Arimidex (anastrozole) offer another option, although they may have a more significant financial cost compared to anti-estrogens.

It’s important to note that nandrolone has progestogenic properties; its effects can mimic those of estrogen, including testosterone suppression and increased fat storage. Monitoring can help, and an anti-estrogen might suffice to manage gynecomastia caused by nandrolone.

Side Effects (Androgenic)

Despite its classification as an anabolic steroid, nandrolone can produce androgenic effects, particularly at elevated doses. Users may experience oily skin, acne, and increased body or facial hair growth. For women, virilizing effects—such as voice deepening and menstrual irregularities—are potential risks. However, nandrolone’s lower androgenic activity means a higher dosing threshold is needed to trigger significant androgenic responses compared to more potent steroids like testosterone.

Side Effects (Hepatotoxicity)

As nandrolone is not c-17 alpha alkylated, it is unlikely to induce hepatotoxicity in healthy individuals.

Side Effects (Cardiovascular)

Anabolic steroids may negatively impact cholesterol levels, decreasing HDL (good) cholesterol and increasing LDL (bad) cholesterol, potentially heightening arteriosclerosis risks. Research on nandrolone decanoate indicates a 26% decrease in HDL levels at 600mg per week for 10 weeks—a greater suppression than seen with testosterone enanthate. While nandrolone decanoate poses less lipid disturbance than c-17 alpha alkylated equivalents, cardiovascular risks—including elevated blood pressure and altered triglyceride levels—remain concerns.

Side Effects (Testosterone Suppression)

All anabolic steroids suppress endogenous testosterone production at effective muscle-boosting doses. Research indicates that 100mg weekly of nandrolone decanoate can decrease serum testosterone levels by about 57% over six weeks, reaching 70% suppression at 300mg. Progestational activity is believed to contribute to testosterone synthesis suppression, and normal levels may take 2-6 months to recover without aid. Prolonged use can lead to hypogonadism, necessitating medical intervention:

Administration (Men)

For optimal anabolic effects, initial guidelines suggested 25-50mg weekly for 12 weeks. Most physique-enhancers utilize 200-400mg weekly over 8-12 week cycles, ensuring effective muscle mass and strength gains. The rapid release of the phenylpropionate ester typically necessitates splitting doses across two applications.

Administration (Women)

For women, early guidelines advocate a dosage of 25-50mg weekly for 12 weeks. For enhancements, 50mg weekly typically suffices, administered as a single injection over 4-6 weeks. Higher doses or extended use carry risks for androgenic side effects; immediate cessation is recommended upon signs of virilization to avoid permanent changes.
