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

Нандролон фенілпропіонат

Нандролон фенілпропіонат is a potent injectable anabolic steroid, exhibiting benefits similar to Deca-Durabolin, which utilizes the more gradual nandrolone decanoate. The key distinction lies in the rate of nandrolone release; while nandrolone decanoate sustains effects for around three weeks, nandrolone phenylpropionate functions effectively for about one week. Consequently, Deca-Durabolin can be administered every two to three weeks, whereas Durabolin requires injections every few days to weekly. Both steroids are interchangeable in performance enhancement, favored by athletes for promoting strength and lean muscle mass with minimal estrogenic or androgenic issues.

Структурні характеристики

Nandrolone phenylpropionate features a modified structure, where the propionic phenyl ester is attached to the 17-beta hydroxyl group, causing slower absorption post-injection due to its less polar nature. After entering circulation, the ester is hydrolyzed, activating the free nandrolone. This design extends therapeutic efficacy, allowing less frequent dosing. Following a deep intramuscular injection, users experience a rapid increase in nandrolone availability within 24 to 48 hours, tapering off to baseline after one week.

Побічні ефекти (естрогенні)

Nandrolone exhibits a reduced propensity for estrogen conversion, around 20% compared to testosterone. This lower conversion rate is largely due to nandrolone’s lower activity in fat tissue. While estrogen-related issues like water retention and gynecomastia may arise, particularly at higher doses, anti-estrogens such as clomiphene citrate or tamoxifen may be deployed to mitigate these effects. Aromatase inhibitors like Arimidex can also be utilized for enhanced control of estrogen synthesis despite their higher cost and potential blood lipid impacts.

Additionally, nandrolone acts as a progestin, binding effectively to its receptor and potentially leading to estrogen-like side effects, including testosterone production inhibition and increased fat storage. A strong interplay exists between progesterone and estrogen, heightening the risk of gynecomastia even in the presence of low estrogen levels, where anti-estrogens can provide relief.

Побічні ефекти (андрогенні)

Despite its classification as an anabolic steroid, nandrolone may trigger androgenic effects, particularly at high dosages. Users might experience oily skin, acne, and increased hair growth. Additionally, women could face virilizing effects such as voice deepening and menstrual irregularities. Nandrolone’s low androgenic activity means that users may experience fewer complications compared to stronger agents like testosterone. Nevertheless, the possibility of libido decline exists in males when not supplemented with other androgenic substances.

It’s important to note that in androgen-sensitive tissues, nandrolone is converted to dihydronandrolone (DHN), which lessens its androgenicity. Thus, using a 5-alpha reductase inhibitor like finasteride could amplify androgenic side effects.

Побічні ефекти (гепатотоксичність)

Nandrolone is not classified as a c-17 alpha alkylated substance and is not associated with hepatotoxicity in healthy users, making liver damage unlikely.

Побічні ефекти (серцево-судинні)

Anabolic steroids can adversely affect cholesterol levels, reducing HDL while increasing LDL cholesterol, leading to potential arteriosclerosis risks. Research shows that a 600mg weekly nandrolone decanoate administration can lead to a 26% HDL reduction, slightly more than with testosterone enanthate. While nandrolone decanoate proves less impactful on serum lipids than c-17 alpha alkylated steroids, it may still affect hypertension and triglyceride levels, thereby increasing cardiovascular disease risk.

Побічні ефекти (пригнічення тестостерону)

All anabolic steroids, when taken in sufficient amounts, suppress natural testosterone production. Studies have found that a weekly 100mg nandrolone decanoate dose can dip testosterone levels by around 57%, increasing to 70% at 300mg weekly. The progestatogenic characteristics of nandrolone may exacerbate this suppression. Typically, testosterone levels normalize between 2 to 6 months post-therapy, though prolonged low testosterone can occur, requiring medical intervention.

Адміністрація (чоловіки)

For optimal anabolic results, initial guidance recommended 25 to 50mg weekly over 12 weeks. Most users pursuing physique enhancement target doses between 200 to 400mg weekly in cycles lasting 8 to 12 weeks, often splitting the dosage into two equal applications due to the quick release of the phenylpropionate ester.

Administration (Women)

Similar guidelines advise a 25 to 50mg weekly dose for women over 12 weeks. For performance enhancements, 50mg weekly in a single injection is common, taken for cycles of 4 to 6 weeks. Higher doses risk androgenic effects, and any emergence of virilization symptoms necessitates immediate discontinuation of nandrolone phenylpropionate to prevent long-term changes.
