HCG 2500 IU

Dragon Pharma HCG 2500 IU – High-Purity Human Chorionic Gonadotropin

Dragon Pharma HCG 2500 IU is a high-purity lyophilized formulation of Human Chorionic Gonadotropin (hCG), a glycoprotein hormone that acts as an analog of luteinizing hormone (LH). hCG binds to and activates LH receptors, stimulating Leydig cells in research models to produce testosterone and other androgens. Each vial contains 2500 IU of hCG, supplied with a sterile solvent ampule for convenient reconstitution.

hCG research focuses on its ability to mimic LH signaling, making it valuable for studying testicular function, steroidogenesis, and reproductive endocrinology. Unlike LH, hCG has a longer half-life, providing sustained receptor activation in research protocols. For researchers investigating LH receptor biology, testosterone synthesis pathways, or testicular function, Dragon Pharma HCG 2500 IU delivers a research-grade gonadotropin. When researchers seek legit hCG for advanced endocrine studies, Dragon Pharma provides batch-traceable, third-party verified compounds.

Why Athletes & Bodybuilders Are Researching Human Chorionic Gonadotropin

Within performance research communities, hCG is studied for its ability to stimulate endogenous testosterone production via LH receptor activation. Research focuses on its effects on testicular function, spermatogenesis, and steroidogenic pathways. The long half-life of hCG provides sustained LH-like signaling with less frequent administration compared to pulsatile LH.

What Makes Dragon Pharma HCG 2500 IU Different?

• ✔ LH receptor agonist activity – Direct stimulation of Leydig cell testosterone production in research models.
• ✔ Prolonged half-life – Sustained receptor activation compared to native LH.
• ✔ Complete kit with solvent – Includes sterile ampule for convenient reconstitution.
• ✔ Third-party potency verified – Lab tested at 2976 IU (119% of label claim).

For researchers requiring a long-acting LH receptor agonist for testicular function and steroidogenesis studies, legit hCG from Dragon Pharma delivers a professionally manufactured, lab-verified gonadotropin formulation.

Reconstitution, Dosage & Research Guidelines

Reconstitution Instructions

Reconstitute the 2500 IU vial with the provided 1 mL sterile solvent or 1-2 mL of Bacteriostatic Water. Inject solvent into the vial, aiming the stream against the glass wall. Swirl gently to dissolve – do not shake as this can denature the glycoprotein. The recommended reconstitution volume is 1 mL for 2500 IU/mL concentration.

Reconstitution reference: View Bacteriostatic Water

Research Dosing Guidelines

Typical hCG research dosing in animal models ranges from 10-100 IU per injection. Due to its prolonged half-life compared to LH, administration frequency is typically every 3-7 days depending on study objectives.

• ✔ Subcutaneous or intramuscular administration – Both routes effective in research models
• ✔ One 2500 IU vial provides 2500 IU total hCG
• ✔ Research cycles typically run 4-8 weeks for steroidogenesis studies
• ✔ Intermittent dosing (every 3-7 days) due to prolonged half-life

Dosing Volume Guide (1 mL reconstitution – 2500 IU per mL)

Using a standard 0.5 mL insulin syringe with hCG reconstituted with 1 mL solvent:

• ✔ 0.01 mL = 25 IU
• ✔ 0.02 mL = 50 IU
• ✔ 0.04 mL = 100 IU
• ✔ 0.06 mL = 150 IU
• ✔ 0.08 mL = 200 IU
• ✔ 0.10 mL = 250 IU
• ✔ 0.20 mL = 500 IU
• ✔ 0.40 mL = 1000 IU
• ✔ 1.00 mL = 2500 IU
• ✔ Administer subcutaneously into abdominal area or intramuscularly using aseptic technique

How Researchers Are Using hCG

hCG is valued in research for its LH receptor agonist activity and prolonged half-life. Researchers study its effects on Leydig cell function, testosterone synthesis, and reproductive endocrinology.

Popular research stacks include:

• ✔ HCG 2500 IU + Enclomiphene – for combined LH pathway and SERM research. View Enclomiphene →
• ✔ HCG 2500 IU + HMG 150 IU – for combined gonadotropin research protocols. View HMG 150 IU →
• ✔ HCG 2500 IU + Testosterone Enanthate – for comparative androgen and gonadotropin research. View Enantat 250 →

Research Protocol Example (6 Weeks)

• ✔ Weeks 1-6: hCG – 250-500 IU administered every 3-5 days via subcutaneous injection
• ✔ Weeks 1-6: Enclomiphene – 12.5-25 mg daily (optional for LH pathway studies)
• ✔ Washout period: 2-3 weeks for hCG clearance

Important Considerations

• 🔬 hCG acts as an LH analog – directly stimulates Leydig cell testosterone production via LH receptor activation
• 💧 Prolonged half-life (approximately 24-36 hours) compared to native LH (20-30 minutes)
• ⚠️ Dose-dependent testosterone stimulation – relevant for steroidogenesis research
• 📦 Lyophilized format requires proper reconstitution and refrigerated storage
• 📦 Always source Dragon Pharma HCG 2500 IU from verified suppliers with batch traceability

Storage Guidelines

Before Reconstitution (Lyophilized Powder)

• ✔ Store at 2–8°C (36–46°F) – refrigerated
• ✔ Do not freeze – freezing can damage glycoprotein structure
• ✔ Keep in original packaging, away from light
• ✔ Stable for up to 24 months when stored properly
• ✔ Avoid repeated temperature fluctuations

After Reconstitution

• ✔ Store at 2–8°C (36–46°F) – refrigerated
• ✔ Do not freeze – freezing causes degradation
• ✔ Use within 30-60 days for optimal potency
• ✔ Discard any unused reconstituted peptide after 60 days

What to Avoid

• ❌ Freezing – damages glycoprotein structure
• ❌ Leaving at room temperature (>25°C) – accelerates degradation
• ❌ Shaking the vial – gentle swirling only; shaking denatures glycoproteins
• ❌ Using cloudy or particulated solution after reconstitution
• ❌ Storing in bathroom or near heat sources

Inspection Before Use

Before using in your research, always inspect the vial:

• ✔ Lyophilized powder should form a solid cake or pellet at the bottom of the vial
• ✔ Crimp seal must be intact – do not use if seal is broken or missing
• ✔ After reconstitution, solution should be clear and free from particles
• ✔ Check batch number and QR code for authenticity before first use

Keep out of reach of children and unauthorized personnel. Follow institutional laboratory safety guidelines for handling research compounds.
