Frequently Asked Questions (FAQ)

At Amino USA, we set high benchmarks for research peptide purity (>98%). We have partnered with an ISO-certified USA manufacturer to produce all of our research peptides. Our single and blended compounds are freeze-dried (lyophilized) for maximum stability and long-term shelf life.

All research peptides are supplied as lyophilized (freeze-dried) powder in sterile laboratory glass vials with flip-off caps to ensure compound integrity and prevent degradation during transport.

All products sold by Amino USA are strictly intended for in vitro laboratory research, chemical analysis, and scientific investigation only. They are explicitly NOT for human or animal consumption, therapeutic, or cosmetic use.

No. None of our products are manufactured, labeled, or intended for human or animal ingestion or diagnostic use. Any inquiries regarding human dosing, consumption, or therapeutic applications will result in immediate order cancellation and account restriction.

Yes! We welcome custom synthesis and bulk research inquiries. If you require a specific compound, custom peptide sequence, or specialized quantity, please contact our research support team.

Absolutely. Every single batch is independently tested across accredited 3rd-party U.S. laboratories via High-Performance Liquid Chromatography (HPLC) purity analysis and Mass Spectrometry identity testing. You can view all batch test reports in our public COA Library.
