A
Yes. Most catalog items ship as lyophilized powder in sealed research vials to maximize stability during transit and storage prior to reconstitution in your lab.
A
Store unopened lyophilized vials at -20°C or colder. After reconstitution, follow your institutional SOP; many researchers store working solutions at 2–8°C for short-term use.
A
Yes. Published COAs on our Lab Testing page correspond to specific batch/lot numbers. Contact us if you need documentation for a particular shipment.
A
Custom synthesis inquiries are accepted for qualified research accounts. Reach out via the contact page with compound name, quantity, and intended research application.
A
We partner with accredited independent analytical laboratories in the United States specializing in peptide identity, purity (HPLC), and mass confirmation.
A
COAs include product name, analysis date, batch/lot identifier, purity percentage, and testing methodology summary. PDF copies are provided when available.
A
Each new manufacturing lot undergoes third-party analysis before release. Historical COAs remain accessible for transparency and traceability.
A
Standard COA packages focus on identity and purity. Additional assays may be arranged for institutional contracts—contact our team for requirements.
A
We currently ship to research addresses within the United States only. International shipping is not available at this time.
A
Temperature-sensitive items are packed with insulated materials and cold packs when required by product stability data and season.
A
Domestic shipments typically ship via UPS or FedEx with tracking provided by email once the order is released from our facility.
A
In-stock items generally ship within 1–2 business days. Out-of-stock products are backordered and ship when inventory is replenished and released.
A
Products are sold for laboratory research and development use only. Purchasers must be 21 or older and agree that products are not for human or animal consumption.
A
No. These materials are research chemicals not approved for diagnostic, therapeutic, or clinical use. Statements have not been evaluated by the FDA.
A
We do not provide consumption guidance, dosing, or medical advice. For experimental design questions, consult your principal investigator and institutional review policies.
A
Due to the nature of research materials, returns are limited to documented shipping damage or fulfillment errors reported within 48 hours of delivery.
A
Reconstitution protocols depend on sequence and solvent compatibility. Use bacteriostatic water or sterile diluent per your lab SOP and published literature for the compound.
A
Expedited options may be available at checkout for qualified orders. Contact us before placing large institutional orders to coordinate logistics.
A
Match the batch/lot number printed on your vial label to the lot listed on the COA. If numbers differ, contact support with your order ID for assistance.
