Every Batch. Third-Party Tested.

Third-party HPLC, UPLC, and mass spectrometry analysis on every production run. Certificates of Analysis available for every batch number. Independent labs. No self-certified results.

Why COAs matter for Research Integrity

A Certificate of Analysis is a laboratory document confirming the identity, purity, and strength of a research compound. Without a valid COA from an independent laboratory, researchers cannot establish the identity or concentration of a compound used in their assays.
Impure compounds introduce variables that invalidate experimental results. In in vitro research, concentration accuracy directly affects reproducibility. A compound listed as 99% pure but lacking HPLC verification provides no meaningful assurance.
Alpha Health provides batch-specific COAs from named third-party analytical laboratories. Every vial ships with a traceable lot number. COAs are available for download per batch.

How Alpha Health testing compares
Test	Alpha Health	What to watch out for
Purity Analysis	HPLC / UPLC (quantitative)	Titration or IR (qualitative)
Identity Confirmation	Mass Spectrometry (MS)	TLC or FTIR only
Endotoxin Testing	LAL / rFC method	Not tested
Batch-Level COA	Yes - lot-specific	Generic or not provided

Reading a peptide purity chromatogram

HPLC chromatograms display compound peaks over retention time. The main peak represents the target compound. Smaller peaks indicate impurities. Purity percentage is calculated from peak area ratios.

How to evaluate any Supplier's COA

Use this checklist when assessing any research peptide supplier. 0/6 criteria checked.

Does the COA include an identity test (MS or NMR)?Reputable labs run mass spec or NMR confirmation, not just purity.
Is the COA issued by a named third-party laboratory?
Does the COA match the batch number on the vial label?
Is the purity method stated (HPLC, UPLC, UV)?
Does the COA include an endotoxin test result?
Is the COA dated within the last 12 months?
