Products Description

### Systematic introduction of FIERCE brand high-quality oil Testosterone Enanthate (TE200)

#### 1. Product Overview

FIERCE brand **Testosterone Enanthate (TE200)** is a high-concentration injectable oil with testosterone enanthate as the core ingredient, designed for hormone replacement therapy (HRT) and physiological function regulation under medical supervision. As a classic long-acting esterified derivative of anabolic steroids, TE200 has become a widely recognized testosterone preparation in the medical and professional fields for its excellent stability, controlled drug release characteristics and low irritation. Each milliliter of oil contains 200 mg of testosterone enanthate, dissolved in a high-purity carrier oil to ensure sustained release and bioavailability of the drug.

#### 2. Core advantages of the product

1. **Ultra-high purity and safety**

- The raw materials are processed through a multi-step purification process with a purity of ≥99.5%, minimizing the risk of allergies or inflammation caused by impurities.

- Meets USP/EP pharmacopoeia standards, no heavy metal residues, and microbial indicators pass sterility testing.

2. **Long-acting sustained-release properties**

- The long carbon chain (C7) of enanthate delays the release of testosterone, and the blood drug concentration is stable for 7-10 days after a single injection, reducing the inconvenience of frequent injections.

3. **Low-pain formula**

- Low-viscosity carrier oil (such as cottonseed oil or mixed ester oil) is used with benzyl alcohol as a solvent to significantly reduce the incidence of local pain and nodules during injection.

4. **Optimized bioavailability**

- The carrier oil and esterification structure work synergistically to promote the slow absorption of drugs in muscle tissue, with small fluctuations in blood testosterone levels, reducing mood or physical fluctuations.

5. **Wide compatibility**

- Suitable for a variety of hormone cycle schemes, and can be used in combination with other esterified testosterone (such as testosterone propionate) or synthetic steroids to meet personalized medical needs.

#### 3. Physical and chemical properties

1. **Chemical structure**

- **Active ingredient**: Testosterone enanthate (C26H40O3), molecular weight 400.6 g/mol.

- **Ester chain characteristics**: Enanthic acid (Enanthic Acid) as the ester group, carbon chain length C7, balance lipophilicity and hydrolysis rate.

2. **Solubility and stability**

- **Carrier oil**: Refined cottonseed oil or complex ester oil, providing an inert dissolution environment, solubility>200mg/mL at room temperature, no crystal precipitation.

- **Thermal stability**: Long-term stability from -20℃ to 25℃, avoid high temperature (>40℃) or light causing ester chain degradation.

3. **Physical and chemical parameters**

- **pH value**: 6.8-7.4, close to human tissue fluid, reducing injection site irritation.

- **Viscosity**: Dynamic viscosity ≤35 mPa·s at 25℃, ensuring smooth injection (using 23G-25G needle).

#### 4. Appearance and packaging specifications

1. **Visual features**

- **Color**: Transparent light amber, may be light yellow due to differences in carrier oil type, no turbidity or suspended matter.

- **Clarity**: 0.22μm microfiltration to ensure that the solution is sterile and free of particulate impurities.

2. **Packaging design**

- **Specifications**: 10mL sterile glass bottle (Type I borosilicate), standard bromobutyl rubber stopper and aluminum-plastic seal, leak-proof and anti-contamination.

- **Label information**: Contains batch number, expiration date, concentration (200mg/mL), storage conditions and warning signs, in compliance with GMP specifications.

#### 5. Production process and quality control

1. **Manufacturing process**

- **Raw material synthesis**: Enzyme-catalyzed esterification technology is used to ensure directional bonding of ester bonds and reduce by-products.

- **Aseptic filling**: Filling is completed in an ISO 5 clean environment to avoid pyrogen contamination throughout the process.

2. **Quality control testing**

- **Chromatographic analysis**: HPLC verifies the content of the main component (98%-102%), and GC-MS detects solvent residues (benzyl alcohol ≤0.9%).

- **Sterility test**: The membrane filtration method is used for 14 days of culture to confirm that there are no bacteria, fungi and endotoxins (<0.25 EU/mL).

#### 6. Indications and usage guidelines

1. **Applicable population**

- **Primary hypogonadism**: Congenital testicular dysgenesis, postoperative testosterone deficiency.

- **Physical enhancement needs**: Used for auxiliary treatment of muscular dystrophy or osteoporosis under the guidance of a physician.

2. **Dosage regimen**

- **Standard cycle**: 200-400mg (1-2mL) per week, deep intramuscular injection (gluteal muscle or vastus lateralis muscle).

- **Peak monitoring**: It is recommended to test serum total testosterone after 4 weeks of medication (target range: 300-1000 ng/dL).

3. **Injection operation**

- **Disinfection specification**: The injection site is disinfected with alcohol cotton pads in a spiral, and the needle is used and replaced to avoid repeated puncture.

- **Injection technique**: Slow push injection (about 30 seconds/mL), gently press to stop bleeding after injection, and avoid rubbing.

#### 7. Safety and side effect management

1. **Common adverse reactions**

- **Local reactions**: Occasionally redness, swelling, and itching are seen, which can be relieved by cold compress.

- **Endocrine effects**: It may inhibit the secretion of endogenous testosterone and needs to be combined with PCT (post-cycle treatment).

2. **Risk Control**

- **Blood Monitoring**: Regularly check hematocrit (HCT), liver function (ALT/AST) and blood lipids (LDL).

- **Contraindications**: Prostate cancer, severe heart disease, pregnancy.

#### 8. Market Positioning and Comparison with Competitive Products

- **Compared with short-acting esters** (such as testosterone propionate): TE200 does not require daily injections and has better compliance.

- **Compared with mixed ester preparations** (such as Sustanon 250): single ingredients, more stable blood drug concentration, and more predictable side effects.

---

#### 9. Legal and Ethical Considerations

- **Prescription Control**: TE200 is a controlled drug and must be obtained legally with a doctor's prescription. Non-medical abuse is strictly prohibited.

- **Sports Doping Warning**: Listed on the banned list by WADA, athletes will face competition penalties for using it.
