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

Нандролон фенілпропіонат

Nandrolone phenylpropionate is a powerful injectable anabolic steroid closely related to Deca-Durabolin, which utilizes the slower-acting nandrolone decanoate. The key distinction lies in the release speed; the latter lasts around 3 weeks, while phenylpropionate is effective for about a week. Clinically, Deca-Durabolin injections are typically administered every 2-3 weeks, whereas Nandrolone phenylpropionate is given every few days to weekly. Both preparations are interchangeable and favored by athletes and bodybuilders for promoting strength and building lean muscle mass with minimal estrogenic or androgenic side effects.

Структурні характеристики

Nandrolone phenylpropionate features a propionic phenyl ester attached to the 17-beta hydroxyl group, enhancing its absorbability. These esterified steroids release active nandrolone after entering the bloodstream, extending the therapeutic effects. Following a deep intramuscular injection, users can expect a rapid increase in nandrolone levels within 24-48 hours, declining to baseline within a week.

Побічні ефекти (естрогенні)

With a low estrogen conversion tendency (around 20% compared to testosterone), nandrolone poses a lesser risk of estrogen-related side effects. However, elevated estrogen levels at higher doses may lead to water retention, body fat gain, and gynecomastia. Anti-estrogen medications like clomiphene citrate and tamoxifen citrate may be necessary if these side effects arise. Aromatase inhibitors such as Arimidex (anastrozole) can also be used for better estrogen control, albeit they can be costly and might impact blood lipid levels. Notably, nandrolone has progestin activity, which can lead to similar side effects as estrogen, necessitating caution.

Побічні ефекти (андрогенні)

As an anabolic steroid, nandrolone may still cause androgenic side effects, particularly at higher dosages. Users may experience oily skin, acne, and increased body or facial hair. Although having low androgenic activity compared to testosterone, it can still negatively affect libido and lead to male pattern hair loss. Women are also susceptible to virilization symptoms like deepened voice and irregularities in menstrual cycles.

Побічні ефекти (гепатотоксичність)

Nandrolone lacks c-17 alpha alkylation, indicating a low likelihood of hepatotoxic effects in healthy individuals.

Побічні ефекти (серцево-судинні)

Anabolic/androgenic steroids can negatively impact cholesterol levels. Nandrolone has been shown to reduce HDL cholesterol and increase LDL cholesterol, heightening the risk of arteriosclerosis. Dosage, administration route, and steroid type influence these effects. One study indicated that 600mg weekly of nandrolone decanoate led to a 26% drop in HDL levels, slightly more than testosterone enanthate.

Побічні ефекти (пригнічення тестостерону)

Anabolic/androgenic steroids are known to suppress endogenous testosterone production. Research shows that administering 100mg weekly of nandrolone decanoate can reduce testosterone levels by approximately 57% during therapy, reaching 70% at 300mg per week. Progestational activity in nandrolone is believed to play a role in this suppression. Recovery of normal testosterone levels typically occurs within 2-6 months following treatment.

Адміністрація (чоловіки)

For anabolic purposes, early guidelines suggested 25-50mg weekly for 12 weeks. The typical performance-enhancing dosage ranges from 200-400mg per week for cycles lasting 8-12 weeks, with many users achieving significant muscle mass and strength gains. Due to its fast-acting nature, the total weekly dosage is usually divided into two applications.

Administration (Women)

For women, recommended dosages for anabolic effects start at 25-50mg weekly for 12 weeks. For performance enhancement, a common dose is 50mg per week, given as a single injection over 4-6 week cycles. Higher dosages or extended cycles are generally not advised due to virilization risks. If symptoms arise, discontinuation is crucial to prevent permanent changes.
