About Research Peptides

Research peptides are short-chain amino acid sequences used extensively in preclinical and in-vitro studies across fields including regenerative medicine, endocrinology, neuroscience, and immunology. PharmaOrder supplies over 13 lyophilized peptides in research-use-only (RUO) format, each accompanied by a third-party Certificate of Analysis confirming identity, purity (≥98% by HPLC), and absence of endotoxins.

Our peptide catalog spans multiple research domains. BPC-157 and TB-500 are among the most studied sequences in tissue repair models. CJC-1295 and Ipamorelin are widely used in growth hormone secretagogue research. Newer additions like MOTS-c and Epithalon are gaining attention in mitochondrial function and telomere biology studies, respectively.

All peptides are shipped as lyophilized powder in sterile, sealed vials to preserve stability during transit. Each vial is labeled with lot number, peptide mass, and storage instructions. Researchers should prepare with an appropriate laboratory diluent for in-vitro use and store prepared solutions at 2–8°C.

Research Peptides — Frequently Asked Questions

What does research-use-only mean for peptides?
Research-use-only (RUO) means these peptides are sold exclusively for in-vitro laboratory research and are not intended for human or veterinary use. Purchasers must confirm they are acquiring peptides for legitimate research purposes.
How do I verify the purity of a research peptide?
PharmaOrder provides third-party Certificates of Analysis (COA) accessible in your account. COAs include HPLC purity data, mass spectrometry confirmation, and endotoxin testing results. You can also request COAs before ordering by contacting support.
How should I store lyophilized peptides?
Unopened lyophilized peptides should be stored at -20°C for long-term storage or 2–8°C for short-term use. Once prepared, peptide solutions should be refrigerated at 2–8°C and remain laboratory-stable for 2–4 weeks depending on the specific sequence.
What is the difference between lyophilized and liquid peptides?
Lyophilized (freeze-dried) peptides are more stable during shipping and storage because removing water minimizes degradation. Liquid peptides are pre-prepared for convenience but have a shorter shelf life and require cold-chain shipping.
Do you provide batch-specific COA documents?
Yes. Every vial is tied to a specific manufacturing lot, and the COA provided matches that lot number. Our COA documents include HPLC chromatograms, mass spectrometry data, peptide content by weight, and bacterial endotoxin test results.

Research Kits

PharmaOrder research kits are designed to give researchers everything they need to begin a study workflow immediately upon delivery. Each kit includes one or more lyophilized peptide vials, an appropriate laboratory diluent for in-vitro preparation, alcohol prep pads, and detailed handling instructions. Kits eliminate the need to source supplies from multiple vendors and ensure compatibility between components. Our catalog includes kits for individual peptides like PO-S01, PO-S02, and PO-S03, as well as multi-vial formats for BPC-157, TB-500, and other compounds. Each kit is designed for convenience and consistency in research workflows. All kit components are packed in tamper-evident packaging with cold packs when ambient temperatures exceed 25°C. Each peptide vial within the kit includes its own lot-specific Certificate of Analysis. Kits offer a 10–15% cost savings compared to purchasing components individually.
