About us
Research-grade peptides.
No compromises.
Ascend Bio Labs is a US-based supplier of research-grade peptides for in-vitro laboratory use. We exist because researchers deserve a supply chain they can actually verify - from synthesis to delivery.
What sets us apart
Independent third-party testing
Every batch is tested by an independent laboratory using HPLC for purity and LC-MS for identity confirmation. We don't self-test - results come from credentialed external labs.
Public certificates of analysis
Every COA is published on the product page with batch number, test date, lab name, purity percentage, and identity confirmation. You can verify before you buy.
99%+ purity standard
Our minimum purity threshold is 99%. Products are lyophilized under controlled conditions and stored with proper cold-chain handling throughout.
Same-day US shipping
Orders placed before 2pm CT ship the same business day from our US facility. Free shipping on orders over $300. Insulated packaging for temperature-sensitive compounds.
Full domestic supply chain
Synthesized, tested, packaged, and shipped entirely within the United States. No international transshipment, no ambiguous sourcing.
Research use only
All products sold by Ascend Bio Labs are intended strictly for in-vitro laboratory research. They are not for human consumption, veterinary use, diagnostic purposes, or any other in-vivo application. By purchasing from us, you confirm that you are a qualified researcher and that the products will be used in accordance with all applicable regulations.
