ZPHC Oxandrolone 50mg – Available Now in the UK

For the advanced, experienced UK bodybuilder who demands maximum efficacy with minimal tablet burden, ZPHC Oxandrolone 50mg delivers the legendary cutting effects of Anavar in a high-potency, premium pharmaceutical-grade oral formulation. First described in 1962 and introduced for medical use in 1964, oxandrolone is a synthetic androgen and anabolic steroid (AAS) derived from dihydrotestosterone (DHT). It has strong anabolic effects and weak androgenic effects, which gave it a mild side effect profile in that regard and made it especially suitable for use in women at appropriate doses.

The 50mg strength is specifically designed for experienced users who require higher dosing protocols while minimizing the number of tablets consumed daily. A 50mg daily dose is just one tablet, while 100mg daily is two tablets—offering unprecedented convenience for advanced cutting and lean mass preservation cycles.

The Science of Oxandrolone (Anavar)

Mechanism of Action

Oxandrolone is a synthetic androgen and anabolic steroid (AAS) and, as such, is an agonist of the androgen receptor (AR), the biological target of androgens such as testosterone and dihydrotestosterone. It has strong anabolic effects and weak androgenic effects.

Key pharmacological properties include:

• Androgen Receptor Activation: Oxandrolone binds to and activates the androgen receptor to exert its effects on protein synthesis and muscle growth.

• Glucocorticoid Receptor Antagonism: Studies demonstrate that oxandrolone blocks glucocorticoid signaling in an androgen receptor-dependent manner. This is a novel action of oxandrolone to suppress glucocorticoid action via crosstalk between AR and GR. This contributes to its muscle-sparing, anti-catabolic effects.

• No Aromatization: Oxandrolone does not aromatize to estrogen, meaning it has no propensity for producing estrogenic side effects such as gynecomastia and fluid retention.

• Anti-Catabolic Effects: By counteracting cortisol, oxandrolone helps preserve lean muscle tissue during calorie-restricted cutting phases.

Key Benefits of ZPHC Oxandrolone 50mg

• Lean Muscle Gains: Oxandrolone promotes steady, quality lean muscle gains without the water retention and bloat associated with other bulking compounds. Gains are keepable and contribute to a dry, hard look.

• Strength Enhancement: Users report consistent, noticeable strength increases across compound movements, making it valuable for both bulking and cutting phases.

• Muscle Preservation During Cutting: Oxandrolone is renowned for its anti-catabolic properties, helping athletes retain hard-earned muscle mass while in a calorie deficit. It’s an ideal choice for cutting cycles and contest prep.

• No Estrogenic Activity: As a DHT derivative, oxandrolone does not aromatize to estrogen. This means no water retention, no gynecomastia risk, and a dry, defined look.

• Improved Muscle Definition and Vascularity: By reducing body fat while preserving muscle, oxandrolone contributes to improved muscle definition and vascularity, making it a favourite among competitors.

• Enhanced Protein Synthesis: Oxandrolone increases protein synthesis within muscle cells, promoting nitrogen retention and creating an optimal anabolic environment for muscle growth.

• Convenient High-Potency Dosing: The 50mg strength allows for simplified protocols with fewer tablets.

• Low Androgenic Activity: With weak androgenic effects, oxandrolone causes fewer androgenic side effects like acne and hair loss compared to stronger compounds.

• Triglyceride Reduction: Studies have shown oxandrolone significantly reduces serum triglycerides in certain types of hyperlipoproteinemia.

Important Pharmacokinetic Information

Absorption and Bioavailability

After administration of a single oral dose (10 mg containing 20 μCi of 14C in ethanolic solution), the peak concentration of 14C-oxandrolone in the plasma was 417 (mean) µg per milliliter at 0.50 to 1.50 hours. Bioavailability is approximately 97%.

Half-Life and Distribution

Oxandrolone levels decline in two phases: from 1.5 to 4.0 hours with a half-life of 0.55 hour and from 4.0 to 48 hours with a half-life of 9.4 hours. In adults, the elimination half-life is 9.4-10.4 hours, and in the elderly, it is 13.3 hours. The 50mg strength follows the same pharmacokinetic profile, with higher peak concentrations scaled proportionally.

Metabolism and Excretion

Oxandrolone is primarily metabolized by the kidneys and, to a lesser extent, the liver. The ingested 14C is eliminated predominantly by urinary excretion. In the urine, 43.6% of the administered 14C was excreted in 24 hours and 60.4% in 96 hours. Recovery of 14C in the feces accounted for only 2.8% of the dose. Unchanged oxandrolone accounted for 28.7% of the ingested 14C. Two major metabolites were tentatively identified as oxandrolone and 16β-hydroxyoxandrolone.

How to Use ZPHC Oxandrolone 50mg (Dosage & Cycle Guidance)

CRITICAL: This information is for educational purposes only. Oxandrolone is a potent 17α-alkylated steroid with significant risks, including an FDA BLACK BOX WARNING for peliosis hepatis, liver tumors, and life-threatening blood lipid changes.

• Form & Strength: Each tablet contains 50mg of ZPHC Oxandrolone.

• Medical Dosage: For legitimate medical purposes, the daily adult dosage is 2.5mg to 20mg, given in 2 to 4 divided doses, for courses of therapy lasting 2 to 4 weeks. The 50mg strength is significantly higher than therapeutic doses and is intended for experienced users only.

• Male Bodybuilding Dosage: Most experienced users find 50-100mg daily (1-2 tablets) to be an effective range for cutting and lean mass preservation. Due to the 9.4-10.4 hour half-life, split dosing (morning and evening) is recommended for the 100mg dose, while the 50mg dose may be taken once daily.

• Female Dosage: The 50mg strength is NOT suitable for female use without splitting tablets, and extreme caution is advised. Women typically use 5-20mg daily and must monitor closely for any signs of virilization. Even at low doses, women can experience irreversible virilization, including deepening of the voice and clitoral enlargement.

• Half-Life & Administration: With an oral half-life of 9.4-10.4 hours, split dosing (e.g., morning and evening for 100mg total) is recommended to maintain stable blood levels. The 50mg strength makes this simple—half a tablet (25mg) twice daily for 50mg total, or one tablet twice daily for 100mg total.

• Cycle Length: Due to its 17α-alkylated structure and hepatotoxicity, oxandrolone cycles are typically limited to 6-8 weeks.

• Crucial Support and Monitoring:

  • LIVER SUPPORT IS MANDATORY: As a 17α-alkylated steroid, oxandrolone is associated with cholestatic hepatitis, peliosis hepatis, and liver tumors, which can be fatal. A documented case report describes a 31-year-old man who developed acute liver failure with bilirubin reaching 56.6 mg/dL after using oxandrolone and testosterone cypionate for 5 months. Aggressive liver support (TUDCA, NAC, milk thistle) is absolutely mandatory during and after use.

  • Blood Work: Regular monitoring of liver function, lipid profiles, and serum calcium (in women with breast cancer) is essential.

  • Warfarin Interaction (CRITICAL): Concurrent dosing of oxandrolone and warfarin may result in unexpectedly large increases in the International Normalized Ratio (INR) or prothrombin time (PT). Doses of warfarin may need to be decreased by 80-85% to maintain desirable INR levels.

• Post-Cycle Therapy (PCT): Oxandrolone suppresses natural testosterone production through inhibition of pituitary luteinizing hormone (LH). A comprehensive PCT protocol is essential after any cycle.

Important Safety Information and Warnings

FDA BLACK BOX WARNINGS

• PELIOSIS HEPATIS: A condition where liver and sometimes splenic tissue is replaced with blood-filled cysts has been reported. These cysts are sometimes present with minimal hepatic dysfunction, but at other times they have been associated with liver failure. They are often not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops. Withdrawal of drug usually results in complete disappearance of lesions.

• LIVER CELL TUMORS: Benign and fatal malignant liver tumors have been reported. Withdrawal of drug often results in regression or cessation of progression of the tumor. However, hepatic tumors associated with androgens or anabolic steroids are much more vascular than other hepatic tumors and may be silent until life-threatening intra-abdominal hemorrhage develops.

• BLOOD LIPID CHANGES: Blood lipid changes that are known to be associated with increased risk of atherosclerosis are seen in patients treated with androgens or anabolic steroids. These changes include decreased high-density lipoproteins (HDL) and sometimes increased low-density lipoproteins (LDL). The changes may be very marked and could have a serious impact on the risk of atherosclerosis and coronary artery disease.

Hepatotoxicity

• SEVERE LIVER INJURY: A documented case report describes a 31-year-old man who developed acute liver failure with total bilirubin reaching 56.6 mg/dL (normal <1.2) after using oxandrolone and testosterone cypionate for 5 months. Liver pathology showed bland cholestasis, mild centrilobular inflammation, and perivenular fibrosis.

• Cholestatic Hepatitis: May occur with 17-alpha-alkylated androgens at a relatively low dose.

Drug Interactions

• Warfarin (MAJOR INTERACTION): Concurrent dosing may result in unexpectedly large increases in INR or PT. Warfarin doses may need to be decreased significantly.

• Oral Hypoglycemic Agents: Oxandrolone may inhibit the metabolism of oral diabetes medications.

• Adrenal Cortical Steroids/ACTH: Concomitant administration may increase edema.

Virilization in Women

• IRREVERSIBLE CHANGES: Women are at risk of virilization, including deepening of the voice, hirsutism (excessive facial/body hair growth), acne, and clitoral enlargement. Some virilizing changes in women are irreversible even after prompt discontinuance of therapy. The 50mg strength is NOT recommended for women.

Contraindications

• Absolute Contraindications: Prostate cancer, male breast cancer, breast cancer in females with hypercalcemia, pregnancy (can cause fetal harm), nephrosis, nephritis, hypercalcemia.

• Pregnancy Category X: Oxandrolone has been shown to cause embryotoxicity, fetotoxicity, and masculinization of female animal offspring.

Frequently Asked Questions

What is ZPHC Oxandrolone 50mg?
It is a premium, high-potency pharmaceutical-grade formulation of Oxandrolone, a 17α-alkylated DHT-derived anabolic steroid known for its ability to promote lean muscle gains, enhance strength, and improve muscle definition without significant water retention. The 50mg strength is designed for experienced users requiring higher doses with fewer tablets.

What is the advantage of the 50mg strength over lower doses?
The primary advantage is convenience and reduced tablet burden. A 50mg daily dose requires just one tablet, while 100mg daily requires two tablets—compared to five 20mg tablets or ten 10mg tablets. This simplifies dosing protocols for experienced users.

What is the half-life of Oxandrolone?
Oxandrolone has an elimination half-life of approximately 9.4 to 10.4 hours in adults, with a biphasic decline: an initial half-life of 0.55 hour from 1.5 to 4.0 hours, and a terminal half-life of 9.4 hours from 4.0 to 48 hours. In elderly subjects, the half-life is 13.3 hours. This supports once or twice-daily dosing.

What is the bioavailability of Oxandrolone?
Oxandrolone has an exceptionally high oral bioavailability of 97%, ensuring consistent and predictable absorption.

Is Oxandrolone 50mg suitable for beginners?
ABSOLUTELY NOT. While considered one of the milder steroids, oxandrolone is a potent 17α-alkylated steroid associated with severe hepatotoxicity, including peliosis hepatis and liver tumors, which carry an FDA BLACK BOX WARNING. The 50mg strength is significantly higher than therapeutic doses and is intended only for experienced users who fully understand the risks and necessary precautions.

Is Oxandrolone 50mg suitable for women?
The 50mg strength is NOT recommended for women. While oxandrolone at lower doses is one of the few anabolic steroids used by women due to its weak androgenic effects, the 50mg strength carries significant risks of virilization (deepening of voice, facial hair growth, clitoral enlargement), which can be irreversible even after prompt discontinuance of therapy.

What are the most significant side effects?
The most critical side effects are severe hepatotoxicity (liver damage) , including peliosis hepatis (blood-filled liver cysts) and liver tumors, which carry an FDA BLACK BOX WARNING. A documented case report describes a 31-year-old man who developed acute liver failure with bilirubin reaching 56.6 mg/dL after using oxandrolone and testosterone cypionate for 5 months.
