Research workspace with sample storage and lot documentation

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 tested to a Freedom Diagnostics release standard — with COA documentation linked via QR code upon batch release.

Independent testing, not self-certification

Freedom Diagnostics runs HPLC purity analysis, mass spectrometry identity confirmation, and LAL endotoxin screening as the release standard. When batches release, the QR code on each vial will link to the certificate — with their name on it, not ours.

Documentation on every vial

Each vial carries a reserved lot number. When COA documents are published, a QR code on the label will link to that batch's certificate on Freedom Diagnostics. Lot, expiration, and storage details are on the label.

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.

Laboratory 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-2 TZ, GLP-3 RT, Tesamorelin, MOTS-c, Glow, and the BPC-157/TB-500 blend — each studied in vitro 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.

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.

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.

Lot-numbered. COA upon release.

Every vial carries a reserved lot number. When Freedom Diagnostics issues the certificate, a QR code will link to that batch document.

Ready to verify for yourself?

Reserved lots. Testing standard defined. COA linked upon batch release.

Review reserved lot numbers and testing panels on each product page. Freedom Diagnostics certificates will be published to the COA library and linked via QR code when batches release.
