HPLC tells you how much. LC-MS tells you what. You want both before you trust a vial.

A research sample without a clear label is a future mistake waiting to happen. Compound, lot, reconstitution date. Every time.

What our QC rejects — under-purity, identity mismatch, endotoxin flags, damaged lyophilisate. The lots you see passed the ones you don't.

Lot 2512290132 · GHK-Cu · 99.697% HPLC (independent ISO 17025 lab). COA in reply. For Research Use Only · Not for human consumption.

TB-500: studied in animal-model tissue-repair research. Every product page links its own lot COA — not 'on request,' on the page. For Research Use Only · Not for human consumption.

“For research use only” isn't a marketing phrase to us. It's the scope of what these compounds are for. No dosing, no human-effect claims — on purpose.

Lot 2512290134 · TB-500 · 99.127% HPLC (independent ISO 17025 lab). COA in reply. For Research Use Only · Not for human consumption.

Good lab habits are boring on purpose. Label, date, store, document. Boring is reproducible.

We built KOI around documentation instead of hype. The red circle is a precision mark, not a logo. #ResearchPeptides

Reconstitution, the science (no dosing, just handling): lyophilised → solution changes everything about how a sample should be stored and handled
