JD BioWorks is a small Los Angeles vendor with good COA documentation and a named lab, but a short price list and bank-only payment. As of October 19, 2026, it names ILS Lab, publishes lot-specific COAs and mentions endotoxin testing. We found 15 peptide products, and we could read prices for three of them.
Notice: JD BioWorks' 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
This is JD BioWorks' strongest area. The site has a quality-testing page, a certificates of analysis page, a page on research peptides with lot-specific COAs and a guide to reading a COA. It names ILS Lab, shows lot or batch numbers alongside its certificates and mentions endotoxin or sterility testing.
What's missing: we found no independent tests for JD BioWorks on Finnrick as of October 19, 2026, so all the testing data comes from the vendor. The lab is named, but we did not verify it.
What we like
- A named lab (ILS Lab) and several pages explaining its COAs.
- Lot-specific COAs, with lot or batch numbers shown.
- Endotoxin or sterility testing mentioned.
- Published location, plus shipping, refund and FAQ pages.
- Free FedEx 2Day advertised, with same-day shipping when possible.
What to watch
- Payment is Zelle, ACH or eCheck only. Bank transfers are harder to dispute than card payments.
- No Finnrick tests found.
- No company name or founding year published.
- We could read prices for only 3 of 15 products, and MOTS-c was 33% above the median.
How it compares
JD BioWorks documents its testing better than many vendors we track, but it has no outside test data yet and fewer payment options. See peptide deals this week and our ranked list for alternatives.
Bottom line
JD BioWorks is a good choice if you want lot-specific COAs from a named lab and a published US location. Weigh that against bank-only payment, a small catalog and no independent testing as of October 19, 2026.
