Who We Are
About Vitality Certified Peptides
Vitality Certified Peptides supplies US-made, research-use-only compounds to qualified researchers, with independent third-party testing behind every vial and direct pricing every day. Everything we sell is for laboratory research use only; nothing on this site is for human or veterinary use.
Quality you can verify
Every compound we carry is synthesized in the USA and tested by an independent third-party laboratory using HPLC and LC-MS, covering identity, purity, and net content. We publish the Certificate of Analysis for every lot we sell, and a digital copy of your exact lot's COA is delivered with every order. We never ask you to take quality on faith; the documentation is the product's resume, and it is always available.
Our guarantee
If a lot we shipped ever fails independent verification against its published Certificate of Analysis, we replace it or refund it in full. Because we source directly and skip the middlemen, our listed price is the price, every day, with no gimmick codes. If something arrives damaged or incorrect, tell us within 7 days and we make it right.
Service and fulfillment
In-stock orders ship within 1 business day, Monday through Friday, from within the United States. Every shipment includes tracking, and US shipping is free on orders over $250. Questions are answered by a real person, usually within 1 business day.
Third-party testing, not self-grading
We do not grade our own homework. Each lot goes to an independent laboratory for multi-stage analysis before it is released for sale, and the resulting Certificate of Analysis is published on our Lab Results page and linked from each product's Batch Testing section. See our Quality Assurance page for the full process, from receiving to release.
Transparency
Beyond the COAs, we maintain a Research Library of peer-reviewed literature citations for every compound in the catalog, with verified PubMed references and no editorializing. Every product page lists the compound's CAS number, molecular formula, molar mass, and sequence where applicable, so you always know exactly what is in the vial.
