Frequently Asked Questions

Research peptides are short chains of amino acids used in laboratory studies to investigate biological processes, cellular signaling, and therapeutic pathways. They are strictly for in-vitro and in-vivo research purposes only — not for human consumption, veterinary use, or therapeutic application. Researchers use peptides to study areas such as metabolism, tissue repair, cognitive function, aging, and hormone regulation.

No. All peptides sold by Pharmacy Express 247 are explicitly labeled and sold for laboratory and research use only. They are not for human consumption, veterinary use, or any therapeutic application. By purchasing, you confirm that you are a qualified researcher and will use these products in accordance with all applicable laws and regulations. Each product ships with a “Research Use Only” label and handling instructions.

All our peptides are lyophilized with a minimum purity of 99%, verified through independent High-Performance Liquid Chromatography (HPLC) and mass spectrometry analysis. A Certificate of Analysis (COA) is provided with every order, documenting batch-specific purity, identity, and quantitative data.

A Certificate of Analysis (COA) is a document issued by an independent testing laboratory that verifies the identity, purity, and quality of a specific batch of peptides. Our COAs include HPLC chromatograms, mass spectrometry data, quantitative analysis, and batch numbers. Every order ships with the corresponding COA for full transparency. You can also request a COA before purchasing by emailing us with the product SKU.

Simple products have a single fixed strength and price (e.g., 10mg vial). Variable products offer multiple strength options under one listing (e.g., 5mg, 10mg, 20mg). For variable products, select your desired strength from the dropdown before adding to cart. Prices vary by strength. All options are from the same peptide batch with identical purity standards.

Lyophilized (freeze-dried) peptides should be reconstituted using bacteriostatic water, which contains 0.9% benzyl alcohol to prevent bacterial growth. Slowly inject the water along the inside wall of the vial — do not spray directly onto the peptide powder. Gently swirl until fully dissolved. Never shake vigorously. Reconstituted peptides should be stored at 2-8°C and used within 30 days. Bacteriostatic water is available in our Accessories section.

Unopened, lyophilized peptide vials should be stored in a freezer at -20°C for maximum stability and shelf life. Once reconstituted, store at 2-8°C (refrigerator) and use within 30 days. Protect from direct light and heat. Always handle with clean gloves and sterile equipment to prevent contamination. Do not freeze reconstituted peptides.

When stored properly at -20°C, lyophilized peptides remain stable for 12-24 months from the date of manufacture. Each vial is labeled with a batch number and manufacturing date. After reconstitution, peptides should be used within 30 days when stored at 2-8°C. Always check for any discoloration or particulates before use.

Yes. Every order includes a handling and safety data sheet with detailed instructions for safe laboratory use. This includes recommended personal protective equipment (PPE), handling procedures, spill response, and disposal guidelines. We also provide online resources and video guides on proper reconstitution and storage techniques.

Our peptides are supplied for in-vitro and in-vivo research purposes, including animal models, provided all experiments comply with local ethical guidelines and animal welfare regulations. We do not support or condone any use outside of legitimate research. Researchers are responsible for obtaining necessary approvals from their institutional review boards (IRBs) or animal ethics committees.
