Products Description

### **1. Product Overview**

STADA Trenbolone Enanthate 200 is a long-acting injectable oil containing 200 mg of Trenbolone Enanthate active ingredient per ml. This product uses high-quality carrier oil (such as cottonseed oil or castor oil) as a solvent and prolongs the drug release cycle through esterification technology. It is suitable for medical scenarios that require stable blood drug concentrations (such as severe muscle wasting diseases). Its high-concentration formula reduces the frequency of injections and is a high-end choice among similar products.

### **2. Physical and chemical properties**

#### **1. Chemical structure**

- **Active ingredient**: Trenbolone Enanthate (chemical name: 17β-Hydroxyestra-4,9,11-trien-3-one enanthate)

- **Molecular formula**: C25H32O3

- **Molecular weight**: 392.52 g/mol

- **Ester chain length**: 7 carbon chains (Enanthate ester), providing a half-life of about 10-14 days.

#### **2. Physical properties**

- **Appearance**: Clear oily liquid, light yellow to amber (the color depth depends on the type of carrier oil and the production process).

- **Solubility**: It is extremely fat-soluble and almost insoluble in water. It needs to be esterified to be dissolved in plant-derived carrier oil.

- **Stability**: It can be stored for a long time (usually 2-3 years) under light-proof and sealed conditions. High temperature or light can easily lead to oxidative degradation.

#### **3. Preparation process**

- **Carrier oil**: Low-allergenic cottonseed oil or castor oil is mostly used to ensure sustained release of the drug and reduce irritation at the injection site.

- **Preservative**: May contain benzyl alcohol (1-2%) to inhibit microbial growth.

- **Filtration process**: 0.22μm microfiltration to ensure sterility.

### **3. Pharmacological characteristics**

#### **1. Mechanism of action**

- **Androgen receptor agonist**: It binds to androgen receptors in muscles and bones with high affinity and promotes protein synthesis.

- **Anti-glucocorticoid effect**: It inhibits cortisol activity and reduces muscle breakdown.

- **Erythropoiesis**: It increases hemoglobin concentration and enhances endurance.

#### **2. Pharmacokinetics**

- **Peak time**: Peak blood concentration is reached 48-72 hours after a single injection.

- **Half-life**: About 8-12 days, 1-2 injections per week are required to maintain steady-state concentration.

- **Metabolic pathway**: Hydrolyzed by liver CYP3A4 enzyme to active metabolite Trenbolone, then excreted through the kidneys.

### **4. Core advantages of the product**

#### **1. High efficiency and long-term efficacy**

- **High bioavailability**: Oil sustained-release technology makes the drug absorption rate exceed 90%, which is significantly better than oral dosage forms.

- **Reduce injection frequency**: 200mg/mL high concentration design, a single injection of 1-2mL can meet the weekly dosage requirements.

#### **2. Safety optimization**

- **Low solvent residue**: STADA uses supercritical CO2 extraction technology to reduce the residue of excipients such as benzyl alcohol and reduce the burden on the liver.

- **Low allergy risk**: Refined carrier oil removes non-glyceride impurities to reduce the probability of local redness and swelling.

#### **3. Rigorous process**

- **GMP-compliant production**: Meets EU GMP standards to ensure batch-to-batch consistency and purity (≥99%).

- **Third-party testing**: Some batches provide mass spectrometry analysis reports to verify that there is no heavy metal or microbial contamination.

### **5. Indications and usage specifications**

#### **1. Medical use**

- **Cachexia treatment**: Used for muscle atrophy management in patients with advanced cancer and HIV/AIDS.

- **Severe burn repair**: Accelerate wound healing and protein synthesis (strict clinical monitoring is required).

#### **2. Dosage regimen**

- **Medical dose**: Usually 50-100 mg/week, divided into 1-2 injections, and the course of treatment does not exceed 8 weeks.

- **Contraindications**: Contraindicated in patients with liver and kidney dysfunction, cardiovascular disease, and prostate hyperplasia.

### **6. Safety and side effects**

#### **1. Common adverse reactions**

- **Androgenic effects**: acne, hair loss, increased body hair.

- **Cardiovascular risks**: HDL (good cholesterol) decreases, LDL increases, and long-term use may cause arteriosclerosis.

- **Neurotoxicity**: Some users report anxiety and insomnia (related to the ability to cross the blood-brain barrier).

#### **2. Risk management**

- **Cycle restrictions**: It is recommended to use a cycle of ≤12 weeks, supplemented with liver protectants (such as NAC).

- **PCT (post-cycle therapy)**: SERM drugs such as tamoxifen are required to restore endogenous testosterone secretion.

---

### **7. Storage and stability**

- **Temperature**: It is recommended to store at 2-8℃ and avoid freezing or high temperature (＞30℃).

- **Light-proof**: Brown glass ampoule packaging to prevent ultraviolet degradation.

- **Expiration date**: 36 months in unopened state, it is recommended to use up within 28 days after opening.

---

### **8. Market and regulatory status**

- **Medical market**: Circulated as a prescription drug in some countries, requiring a specialist doctor's prescription.

- **Non-medical use**: Listed as a banned drug by the World Anti-Doping Agency (WADA) and sports federations.

- **Generic drug controversy**: Underground laboratory imitations are rampant, with risks of inaccurate dosage and contamination.

### **9. Summary**

STADA Trenbolone Enanthate 200 represents the high-end technology of anabolic steroid preparations. Its sustained-release design, high purity and strict quality control make it unique in the medical field. However, its potent androgenic activity and potential health risks require users to be under professional medical supervision. Non-medical use is not only illegal, but may also cause irreversible health damage and must be treated with absolute caution.
