Buy HCG 2500 IU – Human Chorionic Gonadotropin by Dragon Pharma
Dragon Pharma HCG 2500 IU is a pharmaceutical-grade lyophilized peptide hormone used in research to support testosterone production, fertility, and post-cycle therapy (PCT). As an analog of luteinizing hormone (LH), Human Chorionic Gonadotropin (HCG) mimics the signals that stimulate natural testosterone release in the testes.
What Is HCG and How Does It Work?
HCG is a glycoprotein hormone produced during pregnancy, but in research settings, it's commonly used to activate LH receptors in males, leading to the synthesis of endogenous testosterone. This action is vital during or after anabolic steroid cycles, where natural testosterone production is often suppressed.
According to the National Institutes of Health (NIH), HCG is widely studied in the context of male hypogonadism, infertility, and hormonal restoration protocols.
Benefits of Dragon Pharma HCG 2500 IU
- Stimulates natural testosterone production via LH receptor activation
- Preserves fertility and testicular size during anabolic cycles
- Essential compound for effective post-cycle therapy (PCT)
- Supports Leydig cell function and endogenous hormone balance
- Improves mood, libido, and energy during hormonal recovery
How to Use HCG in Research Settings
Each 2 mL vial contains 2500 IU of lyophilized Human Chorionic Gonadotropin. After reconstitution with bacteriostatic water, it is administered subcutaneously or intramuscularly. Common protocols include:
- On-Cycle Support: 250–500 IU twice per week
- PCT Use: 500–1000 IU every other day for 2–3 weeks before beginning SERMs
- Fertility Research: 1500–2500 IU 2–3x/week as per study design
Proper HCG protocols are typically followed by agents like Clomid 50 mg or Nolvadex 20 mg to ensure full hormonal recovery.
Who Should Consider HCG in Research?
- Endocrinologists researching hypogonadism reversal
- Fertility specialists examining LH-based testicular stimulation
- Sports scientists studying PCT protocols and hormonal support
- Clinics exploring combined therapies for testosterone preservation
Lab Quality Results

On September 28, 2023, Dragon Pharma's HCG was independently lab-tested and verified to contain 2976 IU of active HCG with a purity of 99.3%. It is packaged in sterile lyophilized form to maintain maximum potency and stability for all research purposes.
Stacking Options for PCT or Support
Dragon Pharma HCG is often stacked with other compounds to optimize recovery and hormonal function:
- Sustanon 270 – to evaluate LH response during suppressed testosterone cycles
- Enantat 250 – for long-ester testosterone baseline studies
- AOD 9604 – to reduce fat gain during hormonal transition
- BPC-157 – to support joint and systemic recovery post-cycle
Legal Status in the USA
HCG is FDA-approved for several medical uses but is also available for research purposes only through trusted suppliers. If you're seeking a verified source, this provider of Dragon Pharma HCG 2500 IU ensures authenticity and cold-chain shipping across the USA.
Side Effects and Safety Profile
When dosed properly in a research context, HCG is well-tolerated. However, elevated doses may lead to increased estrogen via testosterone conversion, requiring the use of an aromatase inhibitor like Femara 2.5 mg. Other rare side effects include bloating, mild injection site irritation, and mood fluctuations.

Dragon Pharma remains a top-tier peptide supplier for researchers seeking high-purity hormones. Their 2500 IU HCG vials undergo strict lab testing and offer excellent reconstitution quality for scientific protocols. For additional hormone therapies, see the full Dragon Pharma product lineup.
Frequently Asked Questions
What is HCG used for in research?
HCG is used to study its effects on testosterone restoration, fertility, testicular stimulation, and PCT recovery in males with hormone suppression.
How is Dragon Pharma HCG 2500 IU administered?
It is reconstituted with bacteriostatic water and injected subcutaneously or intramuscularly, depending on the research design and protocol.
Is HCG legal in the United States?
Yes, HCG is legal for prescription use and also available for scientific research in the USA. It is not legal to use without medical oversight for athletic performance.
Does HCG increase estrogen?
Indirectly, yes. HCG boosts testosterone production, and excess testosterone can convert to estrogen, especially in high doses without aromatase control.
