Welcome to Vendors COMPP
At Vendors COMPP, we specialize in the research, development and production of high-quality peptides for the global scientific community. As a professional peptide manufacturer operating a modern synthesis facility, we have built our reputation on delivering peptide products that meet the exacting standards demanded by pharmaceutical laboratories, academic research institutions and biotechnology companies. Our domain, hxnetpeptide.com, serves as the central hub where researchers can explore our full catalog of peptide synthesis services, study our technical capabilities through the Knowledge Hub, and place orders for custom peptide sequences tailored to their specific experimental needs.
Peptide science has experienced remarkable growth over the past two decades. Peptides occupy a unique position between small molecules and large proteins, offering a combination of high target specificity, low toxicity and favorable pharmacological profiles that make them invaluable tools for both basic research and therapeutic development — from GLP-1 receptor agonists reshaping metabolic research to copper peptides transforming cosmetic science. Vendors COMPP was founded with a clear mission: to provide researchers with reliable, high-purity peptide products and custom synthesis services that accelerate discovery across multiple disciplines.
Our comprehensive approach integrates every stage of the production pipeline, from initial sequence-design consultation through final quality-assurance testing. Whether you require a simple linear peptide for an in vitro assay, a complex modified sequence with non-natural amino acids for structural studies, or a large-scale production run for preclinical evaluation, our team of experienced peptide chemists and QC specialists is equipped to meet your needs.

Research timelines are critical. Our streamlined workflow delivers standard custom peptides in as little as 2–3 weeks, with rush options available for time-sensitive projects.
Expert Scientific Support
Our team includes PhD-level peptide chemists who provide complimentary consultation on sequence design, modification strategies and optimization recommendations to maximize research success.
Comprehensive Modifications
From N-terminal acetylation and C-terminal amidation to fluorescent labeling, phosphorylation and disulfide bridge formation, we offer an extensive range of peptide modifications for diverse applications.
Flexible Scale Options
Whether you need milligram quantities for initial screening or gram-scale production for extensive studies, our capabilities accommodate projects from 1 mg to multiple grams with consistent quality.
Our Core Peptide Services
Vendors COMPP offers a comprehensive suite of services designed to support every aspect of peptide-based research. As a specialized peptide manufacturer, we have developed expertise across the full spectrum of peptide chemistry, enabling us to serve as a single, reliable source for all your synthesis needs.
Custom Peptide Synthesis
Our flagship service is custom peptide synthesis, where researchers can submit any amino acid sequence for production. Using optimized Fmoc-based solid-phase protocols, we construct each peptide chain with precise coupling efficiency, minimizing deletion sequences and maximizing crude purity. Every custom order includes complimentary sequence analysis, in which our scientists review your target sequence for potential synthesis difficulties and proactively recommend strategies to improve yield and purity before production begins.
Peptide Modification and Labeling
Many research applications require peptides with specific chemical modifications or reporter labels. Our capabilities encompass N-terminal acetylation, C-terminal amidation, phosphorylation at Ser/Thr/Tyr residues for kinase substrate studies, biotinylation for pull-down assays, and fluorescent labeling with FITC, TAMRA and Alexa Fluor conjugates. We also specialize in disulfide bridge formation, a critical modification for sequences that require defined three-dimensional conformations for biological activity.
Peptide Purification and Analysis
Following synthesis, every peptide undergoes purification by preparative reverse-phase HPLC. Standard products are delivered at a minimum of 95% purity, with 98% and 99% options available for sensitive applications. Each purified batch is accompanied by a comprehensive Certificate of Analysis that includes analytical HPLC chromatograms, mass-spectrometry data confirming molecular weight, and detailed documentation of synthesis and purification parameters.
Catalog Research Peptide Products
In addition to custom synthesis, we maintain a growing catalog of popular research peptides available for immediate shipment, including healing-factor peptides, GLP-1 class research compounds, nootropic peptides, cosmetic peptides and peptide hormones. See our Products page for the current catalog.
