Oxi K50 Kassel Pharma USA

The product Oxi K50 70 Tabs contains the anabolic-androgenic steroid (AAS) Oxymetholone, which is commonly known by the brand names Anadrol and Anapolon.

Oxymetholone is one of the most potent oral steroids available and is primarily used for rapid, massive weight and strength gains.¹ However, its high potency comes with a significant risk of severe side effects, especially hepatotoxicity (liver damage).² Like all anabolic steroids, its non-medical use is generally illicit and banned by sports organizations.³

Here is a summary of the uses, side effects, and typical stacking information for Oxymetholone.

Why Bodybuilders Use Oxymetholone (Anadrol)

Oxymetholone is known as a mass-building steroid and is typically used at the start of a cycle to "kickstart" gains, or as a bulking agent.

• Massive & Rapid Weight Gain: It is exceptionally effective at promoting extensive gains in body mass, primarily by greatly improving protein synthesis and increasing red blood cell count.⁴ Users often report gaining significant weight (mostly water and muscle) within the first few weeks of use.⁵

• Significant Strength Boost: It is highly valued by powerlifters and bodybuilders for its capacity to produce dramatic increases in raw strength, making it ideal for lifting heavy weights.

• Improved Recovery and Joint Relief: The rapid weight gain and water retention can lubricate joints, which some users find provides relief from joint pain during heavy lifting.

• Synergy in a Stack: Because of its unique structure, it is not converted to estrogen via the aromatase enzyme (it's a DHT derivative).⁶ However, it still causes estrogenic effects (see side effects), but these are thought to be through other mechanisms (possibly direct activation of estrogen receptors), making it an effective compound to stack with other, less potent mass-building injectables.

 Potential Side Effects of Oxymetholone

Oxymetholone is considered one of the most harsh and dangerous oral steroids due to the severity of its side effects, particularly its liver toxicity.⁷

1. Severe Liver Toxicity (Hepatotoxicity)⁸

• Oxymetholone is a 17-alpha-alkylated (17-aa) compound, which makes it highly resistant to liver breakdown and therefore highly hepatotoxic.⁹

• Risks include elevated liver enzymes (AST and ALT), cholestatic jaundice (yellowing of the skin/eyes), and, most critically, serious and potentially fatal conditions like peliosis hepatis (blood-filled cysts in the liver/spleen) and liver tumors (adenomas and carcinomas).¹⁰

2. Estrogenic Side Effects (Despite Non-Aromatization)¹¹

• Water Retention (Bloating): This is one of the most prominent side effects, leading to a "puffy" or "smooth" look.¹²

• Gynecomastia (Gyno):¹³ Enlargement of male breast tissue. Uniquely, Oxymetholone causes estrogenic effects without aromatizing, meaning standard Aromatase Inhibitors (AIs) may not be fully effective, sometimes requiring the use of a Selective Estrogen Receptor Modulator (SERM).¹⁴

3. Cardiovascular Side Effects

• Severe negative impact on cholesterol: It can cause a significant decrease in HDL ("good" cholesterol") and an increase in LDL ("bad" cholesterol"), dramatically increasing the risk of cardiovascular disease, heart attack, and stroke.¹⁵

• Hypertension (High Blood Pressure): Exacerbated by the extensive water retention.

4. Other Side Effects

• Androgenic Effects: Acne, accelerated male pattern baldness, and increased body hair growth.¹⁶

• Hormone Suppression: Strong suppression of natural testosterone production, requiring a base of exogenous testosterone and rigorous Post-Cycle Therapy (PCT).¹⁷

• CNS Effects: Commonly reported side effects include headaches, nausea, diarrhea, and a feeling of anxiety or restlessness ("Anadrol aggression" is sometimes noted).¹⁸

 Best Stack with Oxymetholone

Oxymetholone is almost exclusively used as a kickstarter for the first 4–6 weeks of a longer cycle to rapidly achieve results while the main injectable drugs slowly build up in the user's system.

• For Bulking and Mass:

  • Testosterone (e.g., Testosterone Enanthate or Cypionate): A mandatory base for any cycle to prevent testosterone suppression side effects.

  • Nandrolone Decanoate (Deca-Durabolin) or Boldenone Undecylenate (Equipoise): Injectable compounds that provide sustained, quality muscle gains after the Oxymetholone phase ends.

• Crucial Stacking Rule: Due to its extreme hepatotoxicity, Oxymetholone should NEVER be stacked with other 17-aa oral steroids (like Oxandrolone or Stanozolol/Winstrol), and cycle lengths must be strictly limited to 4–6 weeks. Liver support is strongly recommended.

 4 Frequently Asked Questions (FAQ)

1. How often should Oxi K50 (Oxymetholone) be administered?

• The product has an active half-life of approximately 8 hours. To maintain stable blood concentrations and maximize its effects, the daily dosage (e.g., 50–100 mg/day) is typically split and administered in 2 doses per day (e.g., morning and evening).¹⁹

2. Can women use Oxymetholone?

• No, it is generally highly discouraged. Despite having a low androgenic activity ratio compared to its anabolic rating, its sheer potency means the risk of irreversible virilization (voice deepening, clitoral enlargement, facial hair growth) is extremely high, even at low doses.²⁰

3. Do I need an Aromatase Inhibitor (AI) for Oxymetholone?

• Oxymetholone does not convert to estrogen via the aromatase enzyme, so traditional AIs are often ineffective against its estrogenic side effects (water retention and gynecomastia). Users often need a Selective Estrogen Receptor Modulator (SERM) like Tamoxifen to block the estrogenic effects caused by Oxymetholone's unique mechanism.

4. How long should an Oxymetholone cycle last?

• Due to the risk of severe, potentially fatal liver damage (hepatotoxicity), Oxymetholone is used for a very limited time. Cycles should typically be kept to 4 weeks and should not exceed 6 weeks under any circumstances.
