What we check
The six things that actually tell you whether a source is real.
HPLC purity, not just a percentage
The actual chromatogram — peak shape, retention time, and whether the number on the label matches the graph.
Mass spec identity match
Does the measured mass line up with the peptide it's sold as, within a few daltons? A clean purity number means nothing if the compound is wrong.
Who ran the test, and when
Named third-party lab (Janoshik, Auxilium, etc.) — not an in-house PDF. Dated within the last few months, tied to the batch you're actually looking at.
Batch number that ties together
The batch on the vial, the batch on the COA, and the batch in the listing should all match. We flag when they don't.
What other researchers got from that batch
Reconstitution notes, appearance, packaging photos, shipping times — pulled from Reddit, forums, and Discords, sorted by batch.
A watchlist that actually watches
Save a supplier or compound. Get a nudge when a new COA drops, a batch changes, or community reports shift.

What you get back
A result card, not a wall of PDFs.
Look up a supplier or compound and you get one card with the trust signal, the doc status, what we see across sources, and the gaps worth watching. Every check is saved to your review log so you can track what you've looked into over time.

Where we stand
Less hype. More receipts.
ClearSource is for people who want to do their homework, not get sold to. We don't sell compounds, tell you how to use them, or hand out a "safe suppliers" list. We pull the paperwork together so you can read it for yourself.
