Southern Aminos is a young, low-priced vendor with a named company but no public COAs. As of October 19, 2026, the site names Southern Aminos LLC, founded in 2025, and almost every price we checked was below the median in our index. We found no testing lab, COA page or Finnrick tests.
Notice: Southern Aminos' 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. 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
Southern Aminos mentions endotoxin or sterility testing, but we couldn't find a COA page or a testing lab named anywhere on the site. That means we could not confirm any certificate or match one to a lot number. We also found no independent tests for it on Finnrick as of October 19, 2026.
If you consider this vendor, ask for the COA for your specific lot and the name of the lab that issued it before you order.
What we like
- Prices below our index median on 18 of 19 compounds checked.
- A named company (Southern Aminos LLC) and founding year.
- Endotoxin or sterility testing mentioned.
- Refund policy, terms and package protection pages, plus a research-use-only statement.
What to watch
- No COA page and no named testing lab.
- No Finnrick tests found.
- A short track record: founded in 2025.
- No location, payment methods or shipping terms found on the pages we checked.
- Every price was a markdown from a "was" price, so check that discounts are current.
How it compares
Southern Aminos is among the cheaper vendors we track, but many of them publish COAs and name their labs. See peptide deals this week and our ranked list.
Bottom line
Southern Aminos offers low prices and names its company, but it gives you no public COAs or named lab to check as of October 19, 2026. Low prices don't make up for missing test documentation.
