GHK-Cu

Retatrutide
What do the results mean? A brief explanation.
A reputable peptide report tests three independent criteria. Important: HPLC may show a peptide to be 99.9% pure and it may still contain endotoxins or heavy metals. Each criterion is therefore tested separately . Disclosing all three provides the complete picture.

Purity · HPLC
The high-performance liquid chromatography (HPLC) method separates the sample into its components and shows the percentage of the target peptide, as well as any other peptides or by-products present.
Endotoxins · LAL test
Endotoxins are bacterial residues measured in EU/mg (Endotoxin Units) . The LAL test detects them with high sensitivity. Lower values indicate cleaner production. Detectable trace amounts are normal and reflect the sensitivity of the measurement.
Heavy metals · ICP-MS
The ICP mass spectrometry (ICP-MS) detects even minute quantities of heavy metals such as lead, arsenic, cadmium or mercury — residues that may originate from raw materials or synthesis and are not detected by HPLC.
