Research Peptides: The Foundation of Modern Biomedical Science
Peptides — short chains of amino acids linked by peptide bonds — are among the most versatile tools in modern scientific research. From studying receptor-ligand interactions and signal transduction pathways to investigating novel therapeutic targets, research-grade peptides enable breakthroughs across pharmacology, endocrinology, neuroscience, dermatology, and regenerative medicine.
At Neidan Labs, we bridge the gap between cutting-edge peptide science and accessible, high-quality research compounds. Our catalog includes some of the most studied peptides in the scientific literature — including BPC-157 for tissue regeneration, TB-500 for wound healing, GHK-Cu for gene modulation, and Epithalon for telomerase research — each backed by peer-reviewed publications indexed in PubMed and NCBI.
What sets Neidan Labs apart is our vertically integrated supply chain. We partner directly with FDA-inspected, GMP-certified peptide manufacturers like Hybio Pharmaceutical (SZSE: 300199) and Bontac Bio-Engineering, ensuring batch-to-batch consistency and full traceability from raw amino acid sourcing through SPPS synthesis, HPLC purification, and LC-MS verification. Every product ships with a comprehensive Certificate of Analysis — because reproducible research demands reproducible materials.
Whether you are a university lab, a biotech startup, or an independent researcher, Neidan Labs provides the analytical rigor and global logistics to support your work. We ship to 40+ countries with temperature-controlled packaging, and our team of peptide specialists is available to assist with custom synthesis inquiries, bulk pricing, and technical support.
Frequently Asked Questions
Everything researchers need to know about our peptides, quality standards, and ordering process.
What are research peptides?
Research peptides are short chains of amino acids (typically 2-50) synthesized for scientific investigation. They are used exclusively in laboratory settings to study biological mechanisms, cellular signaling, receptor interactions, and potential therapeutic targets. All peptides sold by Neidan Labs are intended for in-vitro research and educational purposes only.
What is a Certificate of Analysis (COA)?
A COA is an official document that accompanies every Neidan Labs product, providing verified analytical data including HPLC purity results, mass spectrometry confirmation, amino acid sequence verification, and endotoxin testing results. This ensures researchers can trust the identity and quality of every compound they receive.
How are your peptides manufactured?
Our peptides are synthesized using Solid-Phase Peptide Synthesis (SPPS) in GMP-compliant facilities operated by our manufacturing partners Hybio Pharmaceutical and Bontac Bio-engineering. Each batch undergoes multi-step purification via preparative HPLC, followed by rigorous analytical verification including LC-MS and amino acid analysis.
How should I store research peptides?
Lyophilized (freeze-dried) peptides should be stored at -20°C in a sealed, light-protected container. Under these conditions, most peptides maintain stability for 24+ months. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles by aliquoting reconstituted solutions.
Do you ship internationally?
Yes. Neidan Labs provides worldwide shipping to research institutions, universities, and qualified laboratories across 40+ countries. All shipments use temperature-controlled packaging with real-time tracking. Customs documentation and Material Safety Data Sheets (MSDS) are included with every international order.
What payment methods do you accept?
We accept major credit cards (Visa, Mastercard, American Express), bank wire transfers, cryptocurrency (Bitcoin, Ethereum, USDT), and purchase orders from accredited institutions. Volume discounts are available for institutional and recurring orders.
Can I request a custom peptide synthesis?
Absolutely. Through our OEM and custom synthesis program, we offer tailored peptide sequences, modifications (cyclization, PEGylation, fluorescent labeling), and custom dosing formats. Contact our team with your sequence and specifications for a quote — typical turnaround is 2-4 weeks.
What is the difference between lyophilized and reconstituted peptides?
Lyophilized peptides are in a stable, freeze-dried powder form ideal for long-term storage. Before use in experiments, they must be reconstituted (dissolved) using an appropriate solvent such as bacteriostatic water or sterile saline. We supply all peptides in lyophilized form to ensure maximum shelf life and stability during transit.
Are your facilities FDA-approved?
Our primary manufacturing partner, Hybio Pharmaceutical (Shenzhen Stock Exchange: 300199), has passed multiple US FDA on-site inspections at their R&D center and production facilities. They also hold certifications from China NMPA, EU EMA, Brazil ANVISA, Australia TGA, and South Korea MFDS.
What is your return and refund policy?
We stand behind the quality of every product. If you receive a product that does not meet the stated specifications on the COA, we will replace it or issue a full refund. Unopened products in original packaging may be returned within 30 days. Contact our support team for return authorization.
