“Lab Quality” means our peptides are synthesized under strict quality controls and undergo rigorous analytical testing. Every batch is tested for purity (via HPLC), identity (via Mass Spectrometry), and safety (endotoxin and bioburden testing) to ensure they meet the demands of serious research applications.

Yes! Every product we sell is backed by a Certificate of Analysis. You can request the CoA for your specific batch by contacting us with your order number and batch number (found on the vial). We believe in complete transparency.

HPLC (High-Performance Liquid Chromatography) is an analytical technique used to separate, identify, and quantify each component in a sample. For peptides, it tells us the exact purity level. A single peak on an HPLC chart indicates a pure compound; multiple peaks indicate impurities. Our standards require a minimum of 99% purity.

Endotoxins are toxins present in the cell walls of certain bacteria that can remain even after sterilization. In research, they can trigger inflammatory responses and confound experimental data. We perform LAL (Limulus Amebocyte Lysate) testing to ensure endotoxin levels are below 0.1 EU/mg, suitable for sensitive bioassays.

Yes. In addition to our in-house quality control, we send random samples from every production batch to independent, ISO/IEC 17025 accredited laboratories for confirmatory testing. We don’t grade our own homework.

This is an important distinction. Our peptides are labeled “For Research Use Only. Not for Human or Veterinary Use.” They are produced to high purity standards suitable for laboratory investigation (cell culture, animal models, etc.), but they are not manufactured under the specific regulatory approvals required for human pharmaceutical use.

All peptides are shipped as lyophilized (freeze-dried) powder in sterile, medical-grade glass vials. They’re packaged in protective materials to prevent damage during transit. This form is stable at ambient temperatures during shipping.

Yes, we ship to most countries worldwide. International shipping times and costs vary by destination. Please note that customs clearance may cause delays, and the recipient is responsible for any import duties or taxes.

– Domestic (US): 2-4 business days via USPS Priority or UPS Ground
– Expedited: Next-day and 2-day options available at checkout
– International: 7-14 business days depending on destination and customs

Yes, all orders include tracking information. You’ll receive a shipping confirmation email with your tracking number as soon as your order leaves our facility.

Upon receipt, store lyophilized peptides in a cool, dry place away from light. For long-term storage (weeks to months), refrigeration at 2-8°C (36-46°F) is recommended. For very long-term storage, -20°C may be appropriate. Once reconstituted, peptides should be refrigerated and used within a short timeframe (refer to the product’s data sheet).

In the rare event that your package arrives damaged, please take photos of the damage and contact us immediately at support@[yourcompany].com. We’ll arrange a replacement or refund promptly.

Our inventory is updated in real-time. If a product shows as “In Stock,” it’s available for immediate shipping. Out of stock items typically have a restock timeframe listed on the product page.

Our standard is ≥99% purity as verified by HPLC analysis. Some products may exceed this standard. Exact purity for each batch is available on the Certificate of Analysis.

Yes, most products are available in multiple vial sizes (typically 2mg, 5mg, 10mg). Check individual product pages for available options. Contact us for bulk sizes not listed.

Lyophilized peptides typically have a shelf life of 12-24 months when stored properly. Each vial includes an expiration date. Once reconstituted, peptides should be used within a shorter timeframe (usually 30-60 days depending on storage conditions).

Possibly. If you need a specific peptide for your research that isn’t in our catalog, contact us with the details. We may be able to source it through our manufacturing partners for qualified research projects.

We can provide general guidance on proper reconstitution techniques, including recommended solvents and handling procedures. However, optimal reconstitution may depend on your specific research application, and we recommend consulting published literature for your particular use case.

Most peptides reconstitute well in sterile water for injection, bacteriostatic water, or sterile saline. Some peptides may require specific solvents (like acetic acid or DMSO) for optimal solubility. Check the product’s data sheet or contact us for peptide-specific recommendations.

Concentration = (Peptide mass in mg) / (Volume of solvent in mL)

For example: If you add 2mL of solvent to a 5mg vial, the concentration is 2.5mg/mL.

Remember to account for peptide content (some peptides include counterions or water). The actual peptide content is listed on the CoA.

We cannot provide specific dosing protocols as this depends entirely on your research model and objectives. We recommend consulting published literature in your field for established protocols.

Lyophilized (freeze-dried) powder is the most stable form for storage and shipping. It must be reconstituted with an appropriate solvent before use. Solutions are pre-dissolved peptides but have shorter shelf lives and require cold-chain shipping. We primarily supply lyophilized peptides for maximum stability.

Due to the nature of research products and chain-of-custody requirements, we cannot accept returns or exchanges on opened products. If you receive a damaged item or there’s an error with your order, please contact us within 48 hours of delivery with photos and your order number.

Absolutely not. All products sold by [Company Name] are strictly for Research Use Only (RUO). They are not for human or veterinary use, not for consumption, and not for clinical use. This is clearly stated on every product page, invoice, and vial label.

By creating an account and placing an order with us, you certify that you are a qualified researcher or are purchasing on behalf of a qualified researcher, and that products will be used only for legitimate laboratory research purposes.

Yes. We take data privacy seriously. We never sell or share your personal information with third parties for marketing purposes. All data is stored securely. See our Privacy Policy for complete details.

Yes, we comply with all applicable laws and regulations in the countries we ship to. However, it is the responsibility of the importer to ensure compliance with local laws. Some countries may have restrictions on research peptides.
