NANDROLONE DECANOATE 300 MG – 10 ML VIAL  Injectable (Deca) Compound

What is Nandrolone Decanoate (Deca)?

Nandrolone Decanoate, commonly known as Deca, Durabolin, or Decox, is an injectable anabolic compound that is one of the most popular and long-standing choices in bodybuilding. It is highly valued for delivering potent anabolic effects with relatively mild androgenic properties, especially at lower doses.¹ Its key feature is a very low aromatization rate, converting to estrogen at approximately 20% the rate of testosterone.

Mechanism and Key Benefits

• Muscle Mass Increase: Known for steady, high-quality muscle gains by significantly increasing nitrogen retention and protein synthesis.

• Joint and Tendon Support: May stimulate collagen synthesis and potentially increase bone density, often providing relief from joint pain during intense lifting (a unique benefit of Nandrolone).²

• Performance & Endurance: Increases red blood cell production, which enhances oxygen transport and may improve endurance and workout performance.³

• Low Estrogenic Risk: Due to its low aromatization rate, it causes fewer estrogenic side effects than Testosterone.

Effective Dosage and Cycle Requirements

The Decanoate ester is long-acting, making this compound convenient for infrequent injections.

• Injection Frequency: Should only be injected once a week to maintain stable levels.

• Dosage Range: Recommended dosage is 100–600 mg per week.

• Bulking Cycle: Typically runs 8–16 weeks at up to 400 mg/week.

• Cutting Cycle: Up to 250 mg/week (requires additional compounds to control any fluid retention).

• Mandatory Stacking (CRITICAL): Deca must be combined with a form of Testosterone and often requires anti-progestin drugs (e.g., bromocriptine, cabergoline) to combat Prolactin-related adverse effects.

 Side Effects and Safety Warnings (CRITICAL)

Nandrolone is a 19-nor compound and poses serious Progestin and hormonal risks.

• Sexual Dysfunction ("Deca Dick"): High risk of severe suppression of natural testosterone and Prolactin-related issues, leading to loss of libido and erectile dysfunction. Testosterone stacking and anti-progestins are essential.

• Progestin/Estrogenic Effects: Can cause Gynecomastia and Water retention due to its low aromatization rate combined with moderate progestogenic activity.

• Androgenic Effects (at high doses): Acne, oily skin, hair loss, and increased aggressiveness.

• Contraindications: Should not be used by individuals with breast/prostate cancer, allergies, high calcium levels, or pregnant women.

• Mandatory PCT: Post Cycle Therapy (PCT) is essential and should include Tamoxifen, HCG, and Clomid.

 Frequently Asked Questions (FAQ)

Q1: Why must Deca be stacked with Testosterone?

Deca severely suppresses the body's natural testosterone production.⁴ If used alone, the user will experience dangerously low testosterone levels (hypogonadism), leading to severe loss of libido and erectile dysfunction ("Deca Dick"). Stacking with exogenous testosterone is mandatory.

Q2: How often should I inject Nandrolone Decanoate?

Due to its long Decanoate ester, the compound has an active life of about three weeks. Therefore, it should be injected only once per week to maintain stable and effective blood concentrations.

Q3: What is the main risk associated with Deca's Progestogenic activity?

The main risk is the potential for Prolactin-induced gynecomastia and severe sexual dysfunction. Progestin activity can cause or worsen these adverse effects even when estrogen levels are normal, necessitating the use of anti-progestin compounds like Cabergoline.

Q4: Is Deca recommended for cutting cycles?

It can be used in cutting cycles (at lower doses, up to 250 mg/week) because its low aromatization reduces fluid buildup. However, its tendency to cause some water retention and its long detection time mean it is usually favored for bulking and is used with caution during pre-contest prep.

Q5: Why might a lack of results after 6 months suggest a fake product?

Nandrolone Decanoate is a powerful anabolic compound.⁵ If used consistently for six months with proper diet and training, it should produce significant, measurable gains. A complete lack of results over such a long cycle duration strongly suggests the product is under-dosed or counterfeit.
