We don't sell peptides.
We tell you what's actually in the vial.
Titrate Testing verifies Certificates of Analysis against the labs that issued them, tracks vendor accuracy over time, and lets you submit your own sample for testing no vendor can influence.
Verify a batch in seconds
Enter the batch or lot ID printed on your Certificate of Analysis. We check it against records submitted directly by the testing lab — not the vendor.
Every vendor, rated on evidence — not marketing
Vendors are placed into a tier based on testing history, not on payment. A vendor cannot buy their way into a higher tier.
Verified
Consistent third-party results across multiple independently-submitted batches.
- 3+ independent samples tested
- No unresolved content discrepancies
- COAs issued by accredited labs
Batch-Verified
At least one batch independently confirmed, but track record is still limited.
- 1–2 independent samples tested
- Minor deviations noted, not disqualifying
- Insufficient history for full rating
Flagged
Confirmed discrepancies between labeled and measured content, or unverifiable COAs.
- Failed independent testing
- COA could not be confirmed with issuing lab
- Unresolved user-reported issues
What we actually test for
Every listed result maps to one of these tests. No test, no listing.
Purity (HPLC)
High-performance liquid chromatography confirms the compound's purity percentage and flags unexpected side-peaks.
Identity (Mass Spec)
Mass spectrometry confirms the molecule is actually what the label claims — not a similar or substituted compound.
Net Content
Measures actual peptide mass per vial against the labeled amount, surfacing underfill or overfill.
Sterility & Endotoxin
Checks for microbial contamination and bacterial endotoxins in injectable-intended products.
Bought something and want it tested independently?
Mail in your own vial, blind to the vendor. This is the only way to catch a problem the vendor's own COA won't show you.
