Product Overview

Human Chorionic Gonadotropin (HCG) is a naturally occurring glycoprotein hormone produced during early pregnancy and plays a well-documented role in reproductive endocrinology. As a research peptide, HCG is widely studied in academic and pharmaceutical laboratory settings for its role in stimulating gonadal function, luteinizing hormone (LH) mimicry, and testosterone biosynthesis pathways. The HCG Peptide Vial available at Direct Anti Peptide is produced to strict research-grade specifications, making it a reliable compound for qualified investigators seeking consistent, reproducible results.

Peptide Structure & Amino Acid Sequence

HCG is a heterodimeric glycoprotein composed of two non-covalently bound subunits: an alpha (α) subunit of 92 amino acids, shared with other pituitary hormones such as LH, FSH, and TSH, and a unique beta (β) subunit of 145 amino acids that confers biological specificity. The beta subunit contains a carboxy-terminal peptide (CTP) extension of 30 amino acids not found in LH, which contributes to HCG’s extended half-life in biological systems. The molecular weight of the intact heterodimer is approximately 36–40 kDa, depending on glycosylation state. This structural complexity makes HCG a particularly valuable compound in research exploring receptor binding kinetics, gonadotropin signaling cascades, and hormonal feedback mechanisms.

Purity & Analytical Verification (HPLC & MS)

Every batch of HCG Peptide Vial supplied by Direct Anti Peptide undergoes rigorous analytical verification to confirm ≥98% purity. High-Performance Liquid Chromatography (HPLC) is employed to assess compound homogeneity and detect trace impurities, while Mass Spectrometry (MS) confirms molecular identity and structural integrity. These dual-verification protocols ensure that researchers receive a compound that meets the highest benchmarks for research-grade material, supporting the reproducibility and validity of experimental outcomes.

Quality Control & Lyophilization Integrity

The lyophilization (freeze-drying) process used in the production of this vial is a critical quality measure. By removing moisture under vacuum at low temperatures, lyophilization preserves the three-dimensional structure of the HCG glycoprotein, preventing degradation that would otherwise occur in aqueous solution. The resulting lyophilized cake is stable, uniform, and resistant to oxidative and hydrolytic breakdown. Each vial is visually inspected for cake integrity, particulate matter, and seal quality prior to dispatch from our fulfillment center.

Safety, Handling & Laboratory Precautions

This compound is intended exclusively for use by trained laboratory professionals operating within a properly equipped research facility. Standard laboratory safety protocols must be observed at all times, including the use of appropriate personal protective equipment (PPE) such as gloves, lab coat, and eye protection. Researchers should consult applicable institutional biosafety guidelines and material safety data references before handling. This product is not approved for use in humans or animals under any circumstances.

Reconstitution, Packaging & Storage

The HCG Peptide Vial is supplied in a sterile, non-reactive borosilicate glass vial sealed with a pharmaceutical-grade rubber stopper and aluminum crimp cap. The glass construction ensures chemical inertness, protecting the delicate molecular architecture of the peptide from reactive surface interactions. Reconstitution should be performed in a sterile laboratory environment using appropriate aqueous buffer solutions as dictated by the specific research protocol. Once reconstituted, the compound should be aliquoted and stored at 2–8°C for short-term use or returned to −20°C for extended preservation. Avoid repeated freeze-thaw cycles to maintain compound integrity.

Intended Research Use & Market Positioning

The HCG Peptide Vial is positioned as a premium research-grade compound for academic institutions, pharmaceutical research organizations, and licensed laboratory facilities investigating gonadotropin biology, endocrine signaling, and reproductive science. It is not intended for any diagnostic, therapeutic, or clinical application. Direct Anti Peptide supplies this compound exclusively to verified research buyers operating within legal and regulatory frameworks applicable to their jurisdiction.
