Frequently asked questions

No. All products facilitated through BioIntegrity are strictly for laboratory research and educational use only. They are not for therapeutic, diagnostic, or medical use in humans or animals.

Every batch undergoes rigorous third-party analysis, including HPLC and MS testing, to verify chemical identity and purity before being added to our catalog.

Yes. Batch-specific COAs are available in our COA Library and are linked on individual product pages.

A document recording analytical results measured on one specific manufactured lot. For research peptides it typically reports purity by HPLC and identity by mass spectrometry, and may report endotoxin. It describes the batch that was tested, not the product line in general.

A certificate records measurements performed on one batch. If the number on the document differs from the number on the label, the certificate describes different material, however similar the product name. Matching the two is the fastest check a buyer can make.

No. Purity describes chemical composition — what fraction of the material is the target sequence. Sterility describes the absence of viable microorganisms and is established by a separate test. The two are not related measurements.

Purity asks how much of the material is the target compound. Identity asks whether the compound present is the one intended. A sample can be highly pure and still be the wrong molecule, which is why both assays appear on a certificate.

It depends on the sequence, the solvent, and storage. Bacteriostatic water addresses microbial growth but not chemical degradation, so a preserved solution is not indefinitely stable. Aliquoting at first reconstitution and freezing single-use volumes preserves material better than any storage temperature applied to a repeatedly accessed tube.

Not automatically. Lyophilised material is far more stable than solution because most degradation pathways require water. Whether an excursion mattered depends on the temperature reached, how long it lasted, and the sequence involved.

No. Several are small molecules — enzyme inhibitors, cofactors, and metabolic precursors — which have no amino acid sequence and therefore no sequence listed on their compound record. They are analysed by the same methods but differ in solubility and degradation behaviour.

We ship domestically within the United States and internationally. International orders are subject to the laws of the destination country; it is the purchaser's responsibility to verify legality in their jurisdiction before ordering, and to satisfy any customs requirements on arrival.

Yes. Products requiring refrigeration are shipped in thermal-insulated packaging with cooling elements to maintain structural integrity during transit.

Due to the refrigerated and research nature of our products, all sales are final upon shipment. We do not accept returns or offer refunds unless the product is damaged or incorrect.

Yes. This site is operated by BioIntegrity, a registered fictitious business name of Triple Seven Distribution LLC, a California limited liability company. biointegritypeptides.com and biointegrityresearch.com both resolve to this site, and enquiries arriving through either reach the same address: info@biointegrityresearch.com.

Purchases are restricted to individuals 18 years of age or older who are qualified laboratory professionals or independent researchers.

Our products are research chemicals. Legal status varies by jurisdiction. It is the buyer's sole responsibility to ensure compliance with all local, state, and federal regulations.

No. All compounds in this catalogue are unapproved for human use. Regulatory activity during 2026 concerned pharmacy compounding eligibility, which is a separate question from drug approval and does not alter the research use only designation.

Not for research supply. The April removals and the July advisory vote both concerned the Section 503A compounding framework, which governs pharmacy preparation against a prescription. Neither action approved any compound for human use.
