How is my order shipped?
Orders ship same-day when placed before 2pm MT, packed with cold-chain-appropriate materials to protect lyophilized peptides in transit. Domestic priority shipping is available at checkout, and orders over $200 ship free.
Where can I find a Certificate of Analysis?
Every product page links to its most recent batch COA. If you need a COA for a specific lot number, contact our support team with your order number and we will send it directly.
What testing standards do you follow?
Each production batch is sent to an independent third-party lab for HPLC purity analysis, mass spectrometry identity confirmation, and endotoxin screening before it is approved for sale.
Are your peptides research-grade?
Yes. Every Veyra Peptides product is manufactured to research-grade purity standards, generally 99% or higher, and independently tested before release.
How is Veyra different from other suppliers?
We keep a tight, deliberately curated product line, publish batch-level testing for everything we sell, and staff support with people who have real lab experience.
What is lyophilization and why does it matter?
Lyophilization (freeze-drying) removes water from a peptide while preserving its molecular structure, which extends shelf stability until the compound is reconstituted for research use.
How should peptides be stored?
Lyophilized powder should be stored at -20°C, away from light and moisture. Once reconstituted with bacteriostatic or sterile water, most compounds remain stable under refrigeration for up to 14 days — always check the specific product page for exact storage guidance.
Do you sell outside the United States?
Currently we ship only within the United States to verified research and institutional addresses. Reach out to our team if you have a specific institutional shipping need.
