Euro-Pharmacies Nandrolone Phenylpropionate 10 ml vial (100 mg/ml) ЗАКІНЧЕННЯ ТЕРМІНУ ДІЇ

Нандролон фенілпропіонат

Nandrolone phenylpropionate is a potent injectable form of the anabolic steroid nandrolone, closely resembling Deca-Durabolin, which utilizes the slower-acting nandrolone decanoate. The key distinction lies in the release rate of nandrolone into the bloodstream; while nandrolone decanoate can linger for about 3 weeks post-injection, nandrolone phenylpropionate’s effects are observed for roughly one week. In clinical practice, Deca-Durabolin is typically administered every 2 to 3 weeks, whereas Durabolin requires more frequent doses, ranging from every few days to weekly. Both preparations are largely interchangeable, with athletes and bodybuilders favoring Deca-Durabolin for its ability to enhance strength and support lean muscle mass gain with minimal estrogenic and androgenic side effects.

Структурні характеристики

Nandrolone phenylpropionate features a modified nandrolone structure, incorporating a propionic phenyl ester attached to the 17-beta hydroxyl group. Esterified steroids are less polar and absorbed at a slower rate at injection sites. Once in circulation, the ester is cleaved to free (active) nandrolone. This design helps extend the therapeutic effects, allowing less frequent injections compared to unesterified steroids. The release of nandrolone spikes sharply within 24 to 48 hours of deep intramuscular injection and tapers to baseline within a week.

Побічні ефекти (естрогенні)

This anabolic steroid exhibits a relatively low estrogen conversion rate, approximately 20% that of testosterone. While the liver can convert nandrolone to estradiol, its propensity for aromatization in adipose tissue is significantly lower, making estrogen-related side effects less of a concern compared to testosterone. Elevated estrogen can lead to symptoms such as water retention, increased body fat, and gynecomastia, particularly at higher doses. Employing an anti-estrogen like clomiphene citrate or tamoxifen citrate may be necessary to mitigate these side effects. Alternatively, an aromatase inhibitor such as Arimidex (anastrozole) may be utilized for more efficient estrogen control, though these inhibitors can be costlier and may negatively impact blood lipid levels. Additionally, it’s noteworthy that nandrolone has progestin activity. Its interaction can lead to effects similar to estrogen, such as inhibiting testosterone production and increasing fat storage. An anti-estrogen is often effective in preventing gynecomastia exacerbated by nandrolone.

Побічні ефекти (андрогенні)

Although primarily an anabolic steroid, nandrolone may still produce androgenic side effects, particularly at higher doses, including oily skin, acne, and increased body or facial hair. Anabolic/androgenic steroids can also heighten male pattern baldness risk. Women should be aware of potential virilizing effects such as voice deepening, menstrual irregularities, and clitoral enlargement. Nandrolone’s lower androgenic activity relative to its anabolic properties results in a higher threshold for significant androgen-related effects compared to testosterone or methandrostenolone. It’s important to note that nandrolone can suppress endogenous testosterone production, potentially affecting libido in men when not combined with another androgen.

Побічні ефекти (гепатотоксичність)

Notably, nandrolone is not C-17 alpha alkylated and is generally recognized as safe regarding liver toxicity in healthy individuals.

Побічні ефекти (серцево-судинні)

Anabolic/androgenic steroids can adversely affect cholesterol levels, decreasing HDL (good) cholesterol while increasing LDL (bad) cholesterol, which may heighten arteriosclerosis risk. The impact on serum lipids depends on various factors, including dosage, administration route, and steroid type. A study on weekly nandrolone decanoate doses of 600mg over 10 weeks indicated a 26% reduction in HDL cholesterol levels, a slightly more significant decrease than an equivalent dose of testosterone enanthate. While nandrolone decanoate is less impactful on serum lipids compared to C-17 alpha alkylated steroids, it may still pose risks for blood pressure, triglycerides, and cardiovascular disease.

Побічні ефекти (пригнічення тестостерону)

All anabolic/androgenic steroids can suppress normal testosterone production. Research shows a 57% reduction in serum testosterone levels for a weekly nandrolone decanoate dose of 100mg over 6 weeks; at 300mg per week, the reduction reached 70%. The progestational activity of nandrolone contributes significantly to this suppression. Unless testosterone-stimulating substances are used, testosterone levels usually normalize within 2 to 6 months post-therapy. It is crucial to consider that prolonged steroid abuse can lead to hypogonadotrophic hypogonadism, requiring medical intervention.

Адміністрація (чоловіки)

For anabolic effects, recommended guidelines suggest 25 to 50mg weekly for 12 weeks. For physique or performance enhancement, dosages typically range from 200 to 400mg weekly in 8 to 12-week cycles, allowing users to achieve notable gains in lean muscle mass and strength. Due to the quick onset of phenylpropionate, the dosage is often split into two injections per week.

Administration (Women)

For general anabolic effects, initial guidelines recommend 25 to 50mg weekly over 12 weeks. For physique enhancement, a standard dosage of 50mg weekly (administered in a single injection) is preferred, typically for 4 to 6-week cycles. Higher doses or extended use are discouraged due to potential androgenic side effects. Although mildly androgenic, women may still experience virilization symptoms; thus, immediate discontinuation of nandrolone phenylpropionate is advised to avoid permanent effects.
