What this vendor publishes about itself, repeated here. Disclosure is not verification; only independent lab results change that.
5 certificates on file, all self-published by the vendor. Median purity 99.62%, against 99.66% across all 1,295 certificates we score. Three of five compounds test at or above their market median. The exception is a BPC-157 lot at 99.20% — 0.36 points below the 99.56% median for that compound.
Evidence provenance
- 5 self-published
- COAs the vendor posted on their own site.
Recorded for completeness. A self-published document doesn't count as confirmed on its own — the document is real, the chain of custody isn't independent.

The lab behind these results
In the vendor's own words
Written by the vendor · Not verified by PeptideBase
Harbor Labs is a United States online vendor supplying research-use-only peptides through a Shopify storefront. It publishes a per-batch certificate of analysis on some of its product pages, naming Freedom Diagnostics as the testing laboratory, and prints that laboratory’s own search code on each certificate so a reader can look the record up independently.
