FAQs
How should peptides be stored?
Peptides should be stored according to documented temperature and handling guidelines to maintain compound integrity.
Do you provide Certificates of Analysis (COAs)?
Yes. All products include batch-specific Certificates of Analysis verifying identity and purity through third-party testing. All COAs can be viewed in our COA Library.
Do you offer refunds or returns?
Due to the sensitive nature of research compounds, all sales are final. If something arrives incorrectly or damaged, we’ll fix it.
When will my order ship?
Paid orders are processed and prepared for shipment within two business days of payment confirmation. Once processing is complete, the order is released to the carrier. We don’t sit on orders, and you’ll receive tracking as soon as it moves.
Where do you ship from?
Every order ships directly from our U.S.-based lab, using trusted carriers such as USPS and UPS.
How is product quality verified?
We don’t cut corners. Every batch is GMP-manufactured and independently tested for quality assurance. If it doesn’t meet our standards, it doesn’t leave the lab.
