Testing questions

What is HPLC purity testing?

High-performance liquid chromatography (HPLC) separates the components in a sample. The purity percentage is the share of measured chromatographic signal attributed to the target compound. It measures chromatographic purity, not the quantity in a vial.

What does mass spectrometry confirm?

Mass spectrometry measures mass-to-charge ratios. Comparing the observed and expected mass supports confirmation of the sample’s molecular identity. Your lot report records the method and identity findings.

Who tests Vyal Labs peptides?

Tested by Accurate Test Labs, an independent, accredited U.S. laboratory. Each lot lists its testing laboratory alongside the results.

How do I find the COA for my vial?

Enter the lot number printed on your vial in the COA lookup, or browse the active lot index by compound. If you cannot find a match, contact support with your lot and order number.

Is every batch tested?

Every batch is tested before release by an independent, accredited U.S. laboratory. Lab results are published per lot. 17 of 26 active products (65.3%) have an active COA in this index. If your lot is missing, enter its number in the lookup above or contact support with your lot and order number.

What purity do your peptides test at?

Average purity across 17 lots: 99.616%. Lowest reported: 98.86%. These figures use exact numeric results from active lot records; missing results and results reported only as a bound are excluded. Find your lot for its individual result.
