This page tracks where research compounds and lab materials can be verified: whether a supplier publishes third-party testing, whether certificates of analysis are batch-linked, and what the shipping terms are. Each row carries its own check date so you can judge how fresh the record is. Confirm the final details on the supplier’s own pages before ordering.

What to verify before you order
A COA is only useful if it belongs to the batch you receive. Batch-linked records let you check the exact material in hand.
Independent testing carries more weight than in-house QC. Look for the lab name and method (HPLC, MS, endotoxin).
Cold-chain expectations, dispatch windows, and delivery thresholds change the total cost. Check them before checkout.
Protocol monitoring
Baseline and follow-up bloodwork for research protocols is available through GoodLabs — a Peptide Testing panel covering CBC, lipids, A1c, IGF-1, and insulin resistance (CLIA-certified labs on the Quest Diagnostics and LabCorp networks, no doctor’s visit or insurance needed).
Partner GoodLabs — Peptide Testing panel — 7 tests · 46 biomarkers at $108.

How this list is maintained
Supplier rows are reviewed periodically against each supplier’s public product, testing, and shipping documentation. This is a research reference, not an endorsement or a storefront: confirm everything on the supplier’s own pages before ordering. The compounds listed here are for laboratory research reference, not human or animal use, and this site does not provide medical advice.
