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.
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.
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:
Proper HCG protocols are typically followed by agents like Clomid 50 mg or Nolvadex 20 mg to ensure full hormonal recovery.
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.
Dragon Pharma HCG is often stacked with other compounds to optimize recovery and hormonal function:
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.
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.
HCG is used to study its effects on testosterone restoration, fertility, testicular stimulation, and PCT recovery in males with hormone suppression.
It is reconstituted with bacteriostatic water and injected subcutaneously or intramuscularly, depending on the research design and protocol.
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.
Indirectly, yes. HCG boosts testosterone production, and excess testosterone can convert to estrogen, especially in high doses without aromatase control.
