⚠️ WARNING: Potential Risks of Anabolic Steroids
Anabolic steroids can cause hormonal imbalances, liver strain, cardiovascular issues, and psychological effects, and should only be used under strict medical supervision. Unauthorized or improper use may lead to serious health complications.
If used, obtain these substances exclusively from licensed, verified medical providers to ensure safety and proper oversight.
Soste K – Sustanon Blend (300 mg/ml), Kassel Pharma USA
Soste K 3000 (Kassel Pharma USA) is a multi-ester Testosterone blend commonly known as "Sustanon." This advanced formulation combines four distinct Testosterone esters—Propionate, Phenylpropionate, Isocaproate, and Decanoate—designed to offer both a rapid initial spike in hormone levels and a prolonged, sustained release. This makes Soste K 3000 a versatile base for any anabolic cycle aimed at mass building or performance enhancement.
Each 10 ml vial features a high concentration of 300 mg/ml, allowing users to achieve therapeutic or performance-enhancing dosages with fewer injections compared to lower-concentration compounds.

Key Characteristics and Usage Profile
Immediate and Sustained Action: The four-ester blend ensures that the effects of elevated Testosterone levels are felt quickly and maintained efficiently throughout the week.
Fundamental Compound: As Testosterone, it serves as the base for virtually all effective anabolic cycles, providing the necessary high androgen environment for muscle growth, strength, and recovery.
Mass and Strength: It significantly increases nitrogen retention and protein synthesis, leading to substantial gains in both size and functional strength.
Endogenous Health: As pure Testosterone, it supports optimal masculine health, libido, and energy levels during the cycle.
⚠️ Potential Side Effects and Management
As a highly potent testosterone product (Aromatization: YES), the side effects of Soste K 3000 are strongly linked to estrogen conversion and dosage, requiring careful management.
| Risk Area | Status | Precaution/Explanation |
| Estrogenic Issues | HIGH | Aromatization is YES. The risk of water retention, bloating, and gynecomastia is high, especially at dosages above 500 mg/week. An Aromatase Inhibitor (AI) is essential to control estrogen levels. |
| Androgenic Effects | VARIES | The high conversion to DHT (Dihydrotestosterone) can cause oily skin, acne (especially at high doses), and accelerate hair loss in men genetically predisposed to male pattern baldness. |
| Cardiovascular Strain | PERHAPS | The potential for High Blood Pressure (HBR: PERHAPS) is primarily tied to unmanaged water retention and poor cholesterol maintenance (HDL suppression). |
| Testosterone Suppression | COMPLETE | Like all exogenous Testosterone, Soste K 3000 will cause immediate and complete suppression of natural hormone production, making a robust PCT mandatory. |
Frequently Asked Questions (FAQ)
1. How often should I inject Soste K 3000?
Despite the long 7–8 day active half-life listed, the short esters (Propionate and Phenylpropionate) clear quickly. To maintain stable blood serum levels and minimize peaks and troughs, it is highly recommended to inject twice per week.
2. Is an Aromatase Inhibitor (AI) necessary with Soste K 3000?
Yes. Since the compound strongly aromatizes (Aromatization: YES), an AI (such as Arimidex or Aromasin) is almost always necessary to control estrogen levels, prevent gynecomastia, and mitigate excessive water retention.
3. Is Soste K 3000 better for bulking or cutting?
Testosterone is highly versatile and effective for both. Its mass-building strength is maximized in a calorie surplus. When paired with an AI and stacked with dry compounds, it is excellent for muscle preservation while dieting.
4. What should I use for Post Cycle Therapy (PCT)?
Soste K 3000 is highly suppressive. A PCT protocol utilizing SERMs (like Nolvadex and/or Clomid) is mandatory to signal the body to restart natural testosterone production and retain cycle gains. PCT should start approximately 3 weeks after the final injection due to the blend's long esters.
