How to Read an NAD+ Certificate of Analysis
What KYIN Peptides' NAD+ certificate of analysis actually reports, and how to independently verify it.
What KYIN's NAD+ COA Reports
Every batch of KYIN's NAD+ is independently tested by Janoshik to over 99% purity, with a certificate of analysis available on request for every batch. Unlike the synthetic peptides in KYIN's catalogue, NAD+ is a small-molecule coenzyme rather than an amino-acid chain, so its identity confirmation relies on matching a reference standard's mass spectrometry and chromatographic signature rather than confirming an amino acid sequence.
Why Reference Vial Certificates May Show a Different Fill Size
KYIN's published NAD+ certificate reflects a 500mg reference vial from a specific tested batch; the content figure scales with fill size, but the underlying batch identity and testing apply to the 1000mg vials sold. This is standard practice for multi-size product lines — always confirm that the batch number on the certificate matches the batch number on your vial, rather than assuming the reference certificate applies automatically.
How to Verify Independently
Janoshik publishes verifiable results at janoshik.com/verify using the batch number printed on the certificate. See our general How to Read a Certificate of Analysis guide for the fundamentals that apply across every compound in KYIN's catalogue.
NAD+ testing questions
What purity does KYIN Peptides' NAD+ meet?
KYIN Peptides' NAD+ is independently tested by Janoshik to over 99% purity, with a certificate of analysis available on request for every batch.
Why does the reference certificate show a 500mg vial when I'm ordering 1000mg?
The published reference certificate reflects a smaller sample vial from the same tested batch; the content figure scales with fill size, but the underlying batch identity and testing apply to the 1000mg vials sold.
