Every compound at JDD ships with a batch-specific Certificate of Analysis from an independent US laboratory. No house testing. No recycled COAs. Just the documentation serious researchers actually need.
Every batch. Every time. No exceptions.
Downloadable before you place an order.
HPLC and Mass Spec — both methods, every compound.
Fulfilled from within the USA. No customs delays.
SSL encrypted. Multiple payment methods accepted.

After 2025, the research peptide market lost some of its most recognized names — to enforcement actions, federal charges, and abrupt shutdowns that left researchers mid-protocol with no supplier, no documentation, and no recourse.
JDD was built differently. We keep a focused catalog, maintain independent third-party testing on every batch, and publish COAs before you decide — not after you’ve already paid.
We don’t chase catalog volume. We chase documentation quality, supply chain consistency, and the kind of customer experience that makes researchers come back.

We don’t list a compound until we can document it. Each product page includes the current COA, purity percentage, vial size options, and storage guidance — so you can evaluate before you order.
Not every researcher wants to piece together a protocol from scratch. Our curated bundles combine compounds that are frequently studied in parallel — with a single COA packet covering the full stack.
Five questions. Two minutes. A ranked shortlist of compounds matched to your research goals — with our reasoning shown so you can evaluate the fit yourself.

Many vendors publish a COA. Few of them mean anything. Here’s how to tell the difference — and why it matters for your research validity.
Our compounds go to a third-party US laboratory before they arrive on your product page. The lab runs HPLC for purity percentage and Mass Spectrometry to confirm molecular identity.
The COA you download is tied to the exact batch in our current inventory — not a historical document from a prior lot that may no longer reflect what you receive.
We publish COAs on every active product page. You can read the purity figures and confirm molecular identity before you decide to buy.
Our Education Hub covers peptide mechanisms, storage protocols, COA interpretation guides, and emerging research — so you can make informed sourcing decisions and design better experiments.

First vendor I've used where the COA on the website matched the batch number on the vial. That's not as common as it should be.
