- COA available
What is HCG?
Mimics LH — the brain signal that tells the testes to produce testosterone.
Listed vial contents: 5000 IU. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.
What mechanisms are being studied?
Human Chorionic Gonadotropin is a 237-amino acid glycoprotein that binds LH/CG receptors on testicular Leydig cells, mimicking luteinizing hormone (LH) signaling. It stimulates testosterone production, maintains testicular volume, and supports spermatogenesis. Half-life of 24-36 hours.
What are the research questions?
- Hypogonadism / TRT adjunct: Maintains testicular function and fertility during testosterone replacement therapy. Prevents testicular atrophy.
- Male infertility: Directly stimulates testosterone production and spermatogenesis. FDA-approved for this indication.
- Cryptorchidism (pediatric): FDA-approved for undescended testes in prepubertal males.
- Female fertility (ovulation induction): Used as an ovulation trigger in IVF and fertility protocols.
What does the published work describe?
Coviello AD et al. (JCEM 2008) — Reliable 200-300% testosterone elevation. FDA-approved for multiple indications with decades of clinical data. Extensive use in fertility medicine worldwide.
What are the limits of this evidence?
The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?
Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.
How is HCG handled in the lab?
For HCG, record the product code HCG, selected strength and lot before opening. Follow the material-specific safety data sheet and laboratory SOP, with appropriate gloves, eye protection and containment. For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
For HCG, establish the supplied preparation or construct, formulation and activity documentation before dilution. Protein folding, aggregation, adsorption and excipient compatibility can affect assays. Evaluate compatible vessels and buffer conditions in a small study; do not add a carrier protein unless it is appropriate for the assay and documented in the SOP.
HCG is listed in 5000 IU. International units describe biological activity, not mass. Prepare activity concentrations only from documented lot potency and the relevant assay convention; do not convert IU to mg or molarity with a generic conversion factor.
Use the documented storage conditions for the supplied HCG form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
A HCG laboratory protocol should record identity, product code HCG, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.

Quality & Verification
HCG has a catalog purity specification of ≥99%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
Frequently Asked Questions
What is HCG?
HCG is listed for growth factors laboratory research. Catalog vial contents are 5000 IU; select the required strength before ordering. This material is supplied for Research Use Only, not as a medicine or a product for human or veterinary use.
What strengths of HCG are available?
The catalog lists 5000 IU. These labels describe vial contents, not administration doses. Select the required strength for current pricing and availability; match analysis records to that exact strength and lot.
How should I interpret HCG purity results?
HCG has a catalog purity specification of ≥99%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
How should HCG be handled in the laboratory?

For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
How do I choose a laboratory solvent for HCG?
For HCG, establish the supplied preparation or construct, formulation and activity documentation before dilution. Protein folding, aggregation, adsorption and excipient compatibility can affect assays. Evaluate compatible vessels and buffer conditions in a small study; do not add a carrier protein unless it is appropriate for the assay and documented in the SOP.
How do I calculate a HCG stock concentration?
HCG is listed in 5000 IU. International units describe biological activity, not mass. Prepare activity concentrations only from documented lot potency and the relevant assay convention; do not convert IU to mg or molarity with a generic conversion factor.
How should HCG be stored after preparation?
Use the documented storage conditions for the supplied HCG form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
What should a HCG lab protocol document?
A HCG laboratory protocol should record identity, product code HCG, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Does Fmoc or Boc synthesis explain this HCG product?
The catalog name HCG alone does not establish a synthetic, recombinant or preparation-specific production route. Confirm construct or preparation documentation and relevant analytical or activity methods before drawing conclusions from a peptide synthesis guide.
Is HCG for human use?
No. HCG is strictly Research Use Only. It is not intended for human or veterinary use, diagnosis or treatment. Laboratory handling guidance is not an administration protocol.
Research Use Only. This product is intended for licensed laboratory research and is not for human or veterinary use.
