Rated 4.9 out of 5 across 2,140+ verified purchases.
"The COA matched our in-house LC-MS within 0.2%. That consistency is exactly why we moved our entire peptide sourcing to Argentum."
EDr. Elena M.
Principal Investigator, Molecular Biology
"Arrived next day, still cold, with a temperature log in the box. Support answered a solubility question within the hour."
JJames R.
Lab Manager, Private Research Facility
"We have tested five suppliers over two years. Argentum is the only one where every lot has been within spec."

FAQ
Questions, answered with the same precision.
How do I know the purity claims are real?
Every batch is tested by an independent ISO 17025 accredited laboratory. The batch number printed on your vial links to its full certificate of analysis, including HPLC chromatogram and mass spectrometry data.
How fast is shipping?
Orders placed before 2 PM EST ship the same business day in insulated, cold-chain packaging. Domestic orders typically arrive in 1–3 business days, with tracking sent by email.
What if a product does not meet specification?
If any product fails to meet its stated specification when independently tested, we will issue a full refund or replacement at no cost — no questions asked.
Are your products for human use?
No. All Argentum Labs products are sold strictly for in-vitro laboratory research. They are not intended for human or animal consumption.
Do you offer bulk or institutional pricing?
Yes. Universities, CROs and private research facilities can request volume pricing, net terms and custom synthesis through our contact page.
