Research-Grade Peptides With Published COAs

Specifications are set at 98% or 99% depending on the compound. Purity is quantified by ultra high performance liquid chromatography with mass spectrometry, UHPLC-MS, and identity is confirmed as a separate mass spectrometry test against the expected molecular weight.

The certificate shows the measured result, not just the specification. Measured purity normally sits above the floor.

Yes. Every certificate is published in the open COA Library. No account, no purchase, no request to our team.

Certificates are filed by compound, newest first, and older certificates stay published so the full testing history for each compound remains readable.

Three independent laboratories, none of them owned by us. SafeCert Labs is a CLIA certified facility that issues batch Certificates of Analysis. BioRegen and AV Analytics run identity, quantity and purity analysis by UHPLC-MS, plus endotoxin testing.

Working with more than one laboratory lets us compare results across batches and labs over time, so a figure that looks out of line stands out.

Research peptides are short chains of amino acids produced by chemical synthesis and supplied for laboratory work. Ours are made by solid phase peptide synthesis in United States facilities, lyophilized into powder, sealed in glass vials, and tested for identity, purity and endotoxin before release. They are supplied for in vitro research and for no other purpose.

Six checks separate a testing program from a testing claim. Ask which named laboratories test the batches and whether they sit outside the production chain. Ask whether every batch is tested or only periodic samples. Ask whether certificates can be read before purchase rather than on request afterward. Ask which method confirms identity and whether it is separate from the purity test. Ask whether the vial points you to its certificate, for example through a QR code. Ask where synthesis happens and under what quality framework.

Apply those six to us as well. Our answers are documented on the quality standards page.

Yes. Every batch is screened for endotoxin, and the limit and the pass result are both published on the certificate.

Endotoxin skews cell based assays at trace levels that no purity test can see, because chromatography measures the compound rather than what filling, lyophilization and transit may have introduced. Some labs report it on the certificate itself and some issue a separate endotoxin report, and both are published.

BioRegen certificates carry a COA number and a security key that resolve at bioregen.com/verify. AV Analytics certificates carry a search code you can check at avanalytical.com/coa-search. Older certificates in the library list their own verification details.

Each document also names the analyst who signed it, with a direct address at the laboratory.

Synthesis, testing and fulfillment all happen in the United States, in GMP facilities operating under documented batch records. Chain of custody records are held for every batch.

Domestic production shortens the chain between synthesis and the vial, which means fewer transfer points and fewer places for a batch to lose its paperwork.

In stock compounds ship the same business day on orders placed before 12 PM PT. Domestic orders arrive in 3 to 5 business days standard, or 1 to 2 days expedited.

Lyophilized material ships at ambient temperature in protective packaging. Shipping is free on orders over $400.

Yes, to Canada and a short list of other countries. The country list at checkout shows where we can deliver. Transit times vary by country, and import duties and rules in your country are your responsibility.

Certificates are not packed with orders. Every certificate is in the open COA Library, so you can read or download it at any time.
