Visit Amino USA

Amino USA is a well-identified vendor with fair prices and lot-matched COAs, but limited independent data. It names Amino USA LLC in Austin, Texas, runs a 51-product catalog and publishes COAs tied to lot numbers. Most prices we checked on October 19, 2026 were near or below the median across the vendors in our price index. It doesn't name a testing lab, and Finnrick lists only three tests.

Notice: Amino USA's products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices only. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

Testing and COAs

Amino USA publishes a COA library that lists lot or batch numbers alongside reports, so you can match a certificate to your vial. The site says products are third-party tested for identity, assured to be over 98% pure "or your money back," and lyophilized in the US.

What's missing: no testing lab is named on the site, and we didn't find endotoxin or sterility testing mentioned. Finnrick lists 3 independent tests, which is a small sample.

What we like

  • Named company and city: Amino USA LLC, Austin, TX.
  • Lot-matched COA library.
  • Most prices near or below the index median, with deep discounts on cagrilintide and 5-Amino-1MQ.
  • Large catalog (51 products).
  • Purity money-back promise, same-day shipping and free domestic shipping over $250.

What to watch

  • No testing lab named.
  • No endotoxin or sterility testing mentioned.
  • Only 3 Finnrick tests.
  • NAD priced well above the index median.
  • Only ACH listed as a payment method.

How it compares

Amino USA sits in the value tier with better identification than most low-priced vendors. Compare all vendors we track, peptide deals this week and our ranked list.

Bottom line

Amino USA pairs a named LLC and lot-matched COAs with fair prices. Naming its testing lab and adding endotoxin data would close the main gaps.
