ZPHC HP-HCG 1000 IU (5 Vials)

HP-hCG ZPHC — 5 000 IU kit (5 vials × 1 000 IU)

ZPHC HP-HCG 1000 IU is a high-purity (HP) lyophilized parenteral preparation supplied in a multi-vial pack containing 5 individual vials of 1000 International Units (IU) each of Human Chorionic Gonadotropin (HCG). HCG is a heterodimeric glycoprotein hormone composed of non-covalently linked $\alpha$ and $\beta$ subunits. Functioning as a high-affinity agonist at the LH/hCG receptor, HCG structurally and functionally mimics endogenous pituitary Luteinizing Hormone (LH).

Upon administration, HCG binds directly to G-protein-coupled transmembrane LH/hCG receptors on testicular Leydig cells. This signal cascade activates adenylate cyclase, elevating intracellular cyclic AMP (cAMP) and driving the rate-limiting enzymatic conversion of cholesterol into pregnenolone, thereby sustaining intratesticular steroidogenesis and supporting Leydig cell metabolic function. The 1000 IU unit dosage format allows for precise micro-titration while minimizing multi-dose vial degradation.

Formulated by Zhengzhou Pharmaceutical Co., Ltd. (ZPHC) under cGMP certified cleanroom conditions, each batch undergoes freeze-drying photolysis protection to preserve protein structure and bioavailability.

Mechanism of Action:

hCG mimics the action of the luteinizing hormone (LH), which is responsible for stimulating the testes to produce testosterone. This is especially important during or after anabolic steroid cycles when natural testosterone production may be suppressed. By administering hCG, users can maintain testicular function, size, and testosterone production, preventing common issues such as testicular atrophy. It also supports the recovery of natural testosterone levels during post-cycle therapy (PCT).

Product Features:

• Potency: 1000 IU per vial
• Presentation: 5 vials per pack, offering flexibility in dosing and storage
• Composition: Pure, high-quality hCG for consistent and reliable results
• Stability: Formulated for stability, ensuring potency during the entire storage period
• Usage: Suitable for both intra-cycle testicular maintenance and post-cycle therapy (PCT)

Key Benefits:

• Restores Testosterone Production: Crucial for restoring natural testosterone production post-cycle.
• Prevents Testicular Atrophy: Helps maintain testicular size and function during and after steroid cycles.
• Flexible Dosing: The 1000 IU vials offer convenient dosing options based on individual needs.
• Supports Fertility: hCG is also used to stimulate sperm production, making it valuable for fertility treatments.

Recommended Use:

HP-hCG 1000IU is typically administered via subcutaneous or intramuscular injection. The dosage and frequency will depend on the specific needs of the user, commonly ranging from 500 to 1000 IU every other day. It is essential to consult with a healthcare provider to determine the appropriate dosage and administration schedule for your individual requirements.

Side Effects:

The potential side effects of HP-hCG can include:

• Mild Side Effects: May include headache, mild swelling at the injection site, or mood changes.
• Serious Side Effects: Rarely, users may experience an allergic reaction, characterized by rash, itching, or swelling. Seek medical attention if these symptoms occur.
• Overstimulation: Overuse of hCG can lead to overstimulation of the testes, which may cause discomfort or other complications. It is crucial to follow dosing guidelines carefully.

Contraindications:

HP-hCG should not be used by individuals with prostate cancer, certain types of cancer affecting hormone levels, or those allergic to hCG or its components. It is also contraindicated in pregnant women. Always consult with a healthcare provider before starting hCG to ensure it is appropriate for your health conditions.

Storage Note: Store unconstituted lyophilized vials strictly under cold-chain conditions (2°C to 8°C). Protect from direct light, heat, and mechanical agitation. Once reconstituted with diluent, maintain strict refrigeration (2°C to 8°C) and utilize within the designated stability timeframe. Do not freeze.
