Products Description

#### 1. Product Overview and Market Positioning

FIERCE Testosterone 500 (hereinafter referred to as T500) is a high-concentration testosterone compound oil launched by the internationally renowned pharmaceutical brand FIERCE. It is designed for medical and professional fields that require efficient androgen support. As a rare 500mg/mL testosterone preparation on the market, T500 solves the industry pain points such as high-concentration testosterone crystallization and injection pain through precise formulation and production process innovation, becoming the preferred product for athletes, bodybuilding enthusiasts and hormone replacement therapy (TRT) patients.

#### 2. Chemical composition and formula structure

1. **Active ingredient system**

T500 adopts Multi-Ester Technology (MET) and contains three testosterone derivatives:

- **Testosterone Propionate**: 30% (150mg/mL)

Rapid onset (half-life ≈ 24 hours), reaching the peak blood drug level 24-48 hours after injection.

- **Testosterone Enanthate**: 50% (250mg/mL)

Medium-acting sustained release (half-life ≈ 10.5 days), maintaining stable blood drug concentration.

- **Testosterone Undecanoate**: 20% (100mg/mL)

Long-acting sustained release (half-life ≈ 34 days), reducing injection frequency.

Triesters synergistically form a "step-type release curve", combining rapid start-up and long-term maintenance characteristics.

2. **Carrier oil selection**

Use pharmaceutical grade **Medium chain triglyceride (MCT Oil)** as solvent, with:

- Low viscosity (≈30 mPa·s at 25℃)

- High testosterone solubility (theoretical value reaches 600mg/mL)

- Ultra-low allergy risk (does not contain cottonseed oil/sesame oil sensitizing ingredients)

- Rapid metabolic characteristics (liver first-pass effect reduced by 50%)

3. **Stabilizer and preservative system**

- **Benzyl alcohol (2% concentration)**: has both antibacterial and local anesthetic functions

- **BHT antioxidant (0.1%)**: prevents oxidative degradation

- **Polysorbate 80 (0.5%)**: prevents crystal precipitation
