Delta Peps — Research Use Only Catalog

The catalog built for researchers who already know the difference between 95% and 99%.

Most research peptide suppliers self-report purity. Delta Peps doesn't. Every batch is independently tested by Freedom Diagnostics — and the Certificate of Analysis is a scan away, on every vial.

01

Independent testing, not self-certification

Freedom Diagnostics runs HPLC purity analysis, mass spectrometry identity confirmation, and LAL endotoxin screening on every batch before it enters inventory. Scan the QR code on your vial to access the certificate — with their name on it, not ours.

02

Documentation on every vial

Each vial carries a lot number and a QR code linking to that batch's COA on Freedom Diagnostics. Lot, expiration, and storage details are on the label — no paper certificate is included in the shipment.

03

No health claims. No noise.

This catalog does not use therapeutic language, dosing guides, or performance claims. Products are listed with identity, format, purity, testing data, and availability — the information researchers actually need to make a purchasing decision.

Research-use scope

Why the testing standard matters more than the marketing.

Preclinical research depends on knowing what is actually in a compound — not what the supplier claims is in it. A Certificate of Analysis from an independent laboratory with named analysts, instrument data, and methodology is the only document that tells you what you're working with.

Delta Peps was built around that standard. The catalog covers GLP-1, GLP-2, GLP-3, Tesamorelin, and the BPC-157/TB-500 blend — all investigated in preclinical models for receptor interaction and cellular signaling pathway research.

All products are for RESEARCH USE ONLY. Not for human consumption, medical use, veterinary use, or therapeutic application of any kind.

Why researchers choose verified sourcing

Three things most suppliers don't tell you.

01 Self-reported purity is not the same as tested purity

Many catalogs publish a purity percentage without disclosing who tested it, what instrument was used, or what method. HPLC results from an independent lab with instrument data attached are a different category of claim entirely.

02 Endotoxin testing is routinely skipped

LAL endotoxin assays add cost and turnaround time. Most RUO suppliers omit them. Every batch at Delta Peps passes endotoxin screening before it's listed for sale.

03 Lot-numbered. QR-linked. Documented.

Every vial carries a lot number and a QR code that links to the corresponding Certificate of Analysis. Scan it and you're looking at the same document Freedom Diagnostics issued for that batch.

Ready to verify for yourself?

COA is public. Inventory is live. Every vial QR-linked to its batch document.

Review the Freedom Diagnostics test results before you purchase. The certificate is available on every product page and in the central COA library — and a QR code on every vial links directly to it.
