Bulk Peptide Supply pairs very low prices with a COA library and a solid count of independent tests. When we checked on October 19, 2026, every compound we matched was priced 44-77% below the median of our price index. It names its LLC and has 37 independent tests on Finnrick, but it doesn't name the labs behind its certificates.
Notice: Products from Bulk Peptide Supply 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
Bulk Peptide Supply publishes a COA library. What we did not find on its site: the names of the testing labs, lot or batch numbers shown alongside the certificates, and any mention of endotoxin or sterility testing.
The stronger signal is independent. Finnrick lists 37 tests for this vendor, the most recent dated October 8, 2026. We don't publish Finnrick ratings, so look up the results for the specific compound before relying on it.
What we like
- Prices 44-77% below the index median on all 19 compounds we matched.
- 37 independent tests on Finnrick, recently updated.
- A named company (Bulk Peptide Supply LLC) and a contact address.
- A public COA library.
- Free shipping advertised for orders within the US.
What to watch
- No testing labs named, and no lot numbers shown alongside COAs.
- No endotoxin or sterility testing mentioned.
- Prices this far below the market are worth checking against independent results.
- Payment methods were not listed on the pages we checked.
How it compares
On price alone, Bulk Peptide Supply sits well below the median on every compound we matched. Vendors that name their labs and match COAs to lots give you more to verify. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
Bulk Peptide Supply offers per-mg prices far below our index median, a named LLC and a meaningful number of independent tests. Its certificates are less traceable than the best vendors' because no lab or lot is named. Check Finnrick for your compound first.
