Honest Peptide is one of the cheaper vendors we track, with lot-matched COAs, but it publishes very little about who runs it. Most of its prices sit below the median across the vendors in our price index, including retatrutide and tirzepatide. Its COA library ties reports to lot numbers. The gaps: no company name, no address, no named lab and no Finnrick tests that we could find.
Notice: Honest Peptide'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
Honest Peptide keeps a COA library that lists lot or batch numbers alongside certificates, which lets you match a report to your vial. The site says every batch is third-party tested and mentions endotoxin or sterility testing.
What's missing: the site doesn't name a testing lab, so you can't check reports with the lab directly from what's published. We also found no Finnrick tests for this vendor, so there is no independent data to compare against its own COAs.
What we like
- Most prices below the index median, including retatrutide, tirzepatide, BPC-157 and GHK-Cu.
- Lot-matched COA library.
- Endotoxin or sterility testing mentioned.
- Free shipping on orders above $120.
- A 30-day window to report problems with an order.
What to watch
- No company name, address or founding year published.
- No testing lab named on the site.
- No Finnrick tests found.
- Products listed under codes (GLP-1 S, GLP-2 TZ, GLP-3 R).
- Semaglutide 5mg priced above the index median.
How it compares
On price, Honest Peptide is near the top of the market. On disclosure, it trails vendors that name their lab and company. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
Honest Peptide offers low prices and lot-matched COAs. Until it names its lab and company, or independent tests show up on Finnrick, treat its certificates as the only evidence available.
