Research use only
Verified batches.

Why Delta Peps
Built for researchers who need documentation before they need a checkout button.
Tested by Freedom Diagnostics
An independent ISO-certified laboratory runs every batch — HPLC, mass spec, and endotoxin. Their name is on the COA, not ours.
⚠️ Full Contaminant Screening
HPLC purity. Mass spec identity. Endotoxin. Heavy metals. Sterility. We test for everything. Most vendors skip half of it.
📋 QR-Linked Batch COA
Each vial includes a QR code linking to that batch's COA on Freedom Diagnostics. No paper certificate in the box — scan to access the report anytime.
🔐 Research Integrity, No Noise
No health claims. No dosing language. No supplement-store positioning. For qualified researchers who understand RUO.
