Frequently Asked Questions

1

Are research peptides legal to buy in the United States?

Yes. Peptides marketed and sold strictly as research chemicals for laboratory and analytical use are legal to purchase in the US. NuScience Peptides supplies all products exclusively for research purposes, and every listing carries a research-use-only designation. They are not dietary supplements and are not sold for human consumption.

What are research peptides?

Research peptides are short chains of amino acids synthesized for use in laboratory settings. Researchers use them in cell-based studies, receptor binding assays, peptide synthesis work, and other preclinical or analytical applications. They are not approved drugs and are supplied for in vitro research only.
3

How do you verify peptide purity?

Every batch is tested by an independent third-party laboratory using HPLC (high-performance liquid chromatography) to quantify purity, and mass spectrometry to confirm molecular identity. The results are published as a batch-specific Certificate of Analysis that you can check before ordering.
4

How much do research peptides cost?

Pricing varies by compound and vial size. Individual peptides on our site range from under $30 to over $200 depending on synthesis complexity and quantity. Volume pricing is available for institutional and recurring orders. All current prices are listed on each product page.
