Maste K 1000 – Kassel Pharma USA

Premium Drostanolone Propionate (100 mg/ml)

Maste K 1000 by Kassel Pharma USA contains Drostanolone Propionate, widely recognized as "Masteron Enanthate." This elite injectable compound is a highly prized derivative of Dihydrotestosterone (DHT), making it the ultimate aesthetic finisher for cutting and pre-contest cycles. It is selected for its ability to dramatically increase muscle hardness, density, and vascularity without any associated estrogenic side effects.

Each 10 ml vial contains a concentration of 100 mg/ml. The Propionate ester provides a sustained release over 4.5–5 days, offering the convenience of less frequent injections compared to the Propionate version, while delivering the same high-quality, dry gains.

Key Benefits

• Maximum Muscle Hardness: As a powerful DHT derivative, Maste K 1000 provides an unmatched hardening effect, making muscles appear dense, detailed, and highly defined.

• Anti-Estrogenic Action: It does not aromatize (Aromatization: NO) and, in fact, exhibits mild anti-estrogen properties, helping to lower circulating estrogen and eliminate subcutaneous water.

• Dry, Vascular Look: Zero propensity for water retention (Water Retention: NO) ensures all gains are high-quality, lean muscle, maximizing vascular visibility.

• Libido & SHBG Support: It promotes a strong boost in libido and binds to SHBG, freeing up other anabolic hormones to circulate more effectively.

Potential Side Effects

Maste K 1000 is famous for its mildness, but as a powerful DHT derivative, its androgenic side effects are pronounced:

• Androgenic Effects: The primary risk is linked to its high androgenic rating. The product confirms the potential for Acne (YES). More notably, it is highly potent in accelerating Male Pattern Baldness in men genetically predisposed to hair loss. Users should use caution.

• Cardiovascular Strain: Like all DHT derivatives, Maste K 1000 can negatively impact the lipid profile, specifically by severely suppressing HDL (good cholesterol). A heart-healthy diet and cardio are vital.

• Testosterone Suppression: While not as suppressive as Nandrolone or Trenbolone, Maste K 1000 will still suppress natural testosterone production, requiring a Post Cycle Therapy (PCT) protocol.

Frequently Asked Questions (FAQ)

1. How often should I inject Maste K 1000?

Due to the 4.5–5 day half-life of the Propionate  ester, Maste K 1000 is typically injected twice per week (e.g., every Monday and Thursday) to ensure stable and optimal blood plasma levels.

2. Should Maste K 1000 be used for bulking?

No. Maste K 1000 is an aesthetic finisher. It is not designed to add significant weight or mass. It should be reserved for cutting cycles, pre-contest prep, or recomping when the user has already reached a low body fat percentage (under 12%) for the hardening effects to be visible.

3. Does this product eliminate the need for an AI?

In most cases, no. While Maste K 1000 does not aromatize (Aromatization: NO) and acts as a mild anti-estrogen, it should always be stacked with an injectable Testosterone base. The Testosterone will aromatize, so a dedicated AI is usually necessary to manage the resulting estrogen levels.

4. What is the main advantage of the Propionate version over Propionate?

The main advantage is convenience. Masteron Propionate requires daily or every-other-day injections. Maste K 1000 (Propionate) only requires two injections per week while delivering the same performance benefits.
