With research peptides, the label means nothing without proof. A third-party certificate of analysis (COA) is that proof — an independent lab’s confirmation of what the vial actually contains.
What a COA verifies
- Identity — that the compound is actually retatrutide, usually confirmed by mass spectrometry.
- Purity — the percentage of the sample that is the target peptide, typically by HPLC. Research-grade material should test 99%+.
- Contaminants — screening for impurities and residual solvents.
Why third-party matters
A vendor testing its own product has an obvious conflict of interest. Independent, third-party testing removes it. Every RDAmd batch is third-party tested and published in our COA library — you can verify before you buy.

Domestic synthesis and finishing add a layer of accountability that offshore sourcing often can’t match. Learn what retatrutide is or compare it to other GLP peptides.
