Research-Grade Peptides With Lot-Matched 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 carries the measured result for your lot, not 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 and lot number, and older lots 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 MDx BioAnalytical Laboratory run identity, quantity, purity and endotoxin analysis by UHPLC-MS.

Most suppliers use one outside lab. We use three, so the numbers on a batch can be compared against each other before it ships.

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 batch number on the certificate matches the number on the vial. 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, on every lot, against a threshold of 0.05 EU/mL or lower. The threshold and the pass result are both printed.

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. MDx BioAnalytical certificates carry a COA identifier searchable at mdxbiolabs.com.

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 lot.

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 qualified research institutions and laboratories worldwide. International shipments carry commercial invoices, the batch Certificate of Analysis, safety data sheets and research use only declarations.

Transit times vary by region. Customs duties and import requirements in your jurisdiction are your responsibility.
