HCG Pre-Mixed Pen 5000iu Peptide

Product Overview

Direct Anti Peptide is proud to offer the HCG Pre-Mixed Pen 5000iu — a high-purity, ready-to-use research peptide pen system designed for professional laboratory environments. Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone of significant interest in endocrinological, reproductive biology, and hormonal axis research. This pre-mixed format eliminates the variability associated with manual reconstitution, delivering a consistent, laboratory-grade solution in every cartridge. Researchers can choose between a complete kit or individual replacement cartridges, offering genuine flexibility for ongoing study programmes.

The complete kit includes:

• 1 x Pre-Mixed HCG Cartridge (peptide pre-mixed with Bacteriostatic Water)
• 1 x Peptide Cartridge Pen
• 1 x Pen Carry Case
• 3 x Pen Needle Tips

Single or multi-cartridge options (1, 2, or 3 cartridges) are also available for researchers requiring replacement cartridges without the full kit assembly.

Peptide Structure & Amino Acid Sequence

Human Chorionic Gonadotropin is a heterodimeric glycoprotein composed of two non-covalently associated subunits: an alpha subunit shared with other pituitary glycoprotein hormones and a beta subunit unique to HCG that confers its biological specificity. The beta subunit contains a distinctive C-terminal extension of 24 amino acids not present in luteinising hormone (LH), making it a structurally distinct research target. HCG acts primarily through the LH/hCG receptor (LHCGR), a G-protein coupled receptor expressed in gonadal tissues, making it a central molecule in reproductive endocrinology research models.

Chemical & Physical Characteristics

• Format: Pre-Mixed Cartridge (Bacteriostatic Water)
• Purity: ≥98% (HPLC verified)
• Appearance: Clear to slightly opalescent solution
• Molecular Classification: Glycoprotein hormone
• Receptor Target: LH/hCG Receptor (LHCGR)
• Activity: Gonadotropic

Purity & Analytical Verification (HPLC & MS)

Every batch of HCG supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm a minimum purity of ≥98%. High-Performance Liquid Chromatography (HPLC) is used to quantify peptide purity and detect any residual impurities, while Mass Spectrometry (MS) confirms correct molecular identity and structural integrity. These dual verification methods ensure that researchers receive a product of consistent, documented quality — essential for reproducible experimental outcomes. Certificates of Analysis (CoA) are available upon request for all batches.

Quality Control & Lyophilization Integrity

The HCG peptide component used in this pre-mixed pen system is sourced from lyophilised stock of verified quality before being combined with pharmaceutical-grade Bacteriostatic Water within the cartridge. Lyophilisation preserves the structural integrity of the peptide by removing moisture under controlled vacuum conditions, preventing degradation during storage and transit. Each cartridge undergoes quality control inspection to ensure fill accuracy, seal integrity, and absence of particulate contamination prior to dispatch from Direct Anti Peptide’s fulfilment facilities.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research professionals in properly equipped laboratory settings. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and appropriate lab attire — should be worn at all times when handling peptide cartridges and pen assemblies. Researchers should follow all applicable institutional biosafety protocols. The product must not be used in or on humans or animals under any circumstances. Dispose of used needle tips and cartridges in accordance with local sharps disposal and biohazard waste regulations.

Reconstitution, Packaging & Storage

The HCG Pre-Mixed Pen 5000iu arrives fully pre-mixed, eliminating the need for manual reconstitution in the laboratory. The cartridge is pre-filled with HCG peptide and Bacteriostatic Water, ready for immediate use upon receipt. Store the pre-mixed cartridge refrigerated at 2–8°C and protect from direct light. Avoid freeze-thaw cycling of the pre-mixed solution. The pen carry case included in the full kit provides secure, portable storage for the pen assembly and needle tips during transport between laboratory settings. Individual replacement cartridges are packaged to maintain cold-chain integrity during shipping.

Intended Research Use & Market Positioning

The HCG Pre-Mixed Pen 5000iu is positioned as a premium research tool for scientists and institutions investigating gonadotropin biology, hypothalamic-pituitary-gonadal (HPG) axis signalling, reproductive endocrinology, and steroidogenesis research models. Its pre-mixed, pen-delivered format makes it one of the most convenient HCG research peptide formats currently available for sale online. Direct Anti Peptide supplies this product exclusively for in-vitro and preclinical research applications. It is not intended, approved, or marketed for any therapeutic, diagnostic, or clinical purpose.
