Our lab testLocked / 40Not tested yet
We have not sent a Research Ready Peptides product to an independent lab yet, so these 40 points are locked. The lab report will go on this page when we do.
Reviews6.4 / 20High rating, few reviews
External review sites: ★ 4.6 ± 0.1 average, from under 50 reviews. We show a range because sites round their ratings differently.
That gives 6.4 of 20. We discount review sites a little, so a strong record does not max this on its own.
Community4.5 / 15Little or cautious talk
Forum and Reddit talk is thin or cautious. Nobody has left a review on Peptide Scanner yet.
That gives 4.5 of 15.
Certificates7 / 253 of 12 peptides covered
Publishing: 2 of 15. 14 files from their website that look like certificates are waiting for our check. We have not counted them yet.
Claims match: 5 of 10. Too few of their certificates show a vial or purity result we can check against their product pages, so this part holds a neutral 5.
Their claims against their certificates: 4 certificates read.
A certificate is the shop's own document. It is not our test.

Their certificates vs their claims
No site-wide purity promise found on their website. Vial content is still checked against the label.

- vials outside ±3% of label
- 0 / 0
- beyond ±10% (major)
- 0
- site-wide purity claim to check
- None
How this is checked
- Vial content
- Measured net peptide content against the size on the label. Within ±3% is on label, 3 to 10% is off label, beyond ±10% is a major deviation (under- or overfilled). When a certificate weighs several vials of the batch, the vial farthest from the label is the one judged, and with several purity results the lowest counts. Blends are only checked when the certificate lists each component.
- Purity
- HPLC purity on each certificate against the purity the supplier promises site-wide on its own website. Up to 1 point below the claim is amber, more than that is red. Only a direct promise counts (“99%+ purity guaranteed”); explanations of what purity means, one product's figure and page code are not treated as a claim. A certificate that reports only a bound (“>99%”) is judged only when the bound meets the claim, and a specification line is never read as a result.
- Whose certificate
- A certificate is only read once our client-identity review has looked at it, and one issued to a different company is left out. A certificate issued to the company that runs the supplier's own website counts as the supplier's. A file hosted on another supplier's website is not counted for this one. Only peptide certificates are read: bacteriostatic water, acetic acid and other diluents are left out, and so are product data sheets, which state a specification rather than a batch result.
- Main impurity
- Shown when the certificate itemises it: a named impurity (TFA, deletion sequence, oxidation…) or the largest secondary peak in the HPLC peak table. Most certificates report only a purity figure, so the rest of the sample is not itemised.
- Score
- These checks are 10 of the 25 certificate points: vial content 7 (full credit within ±3%, half up to ±10%, none beyond, over- and underfilled alike), purity 3 (98% is the bar when a supplier advertises no figure). Fewer than 5 readable results gives half credit rather than a guess.
- Source and limits
- These are the supplier's own published certificates, read automatically from the PDF or image. Janoshik results tables are read twice from the image, cell by cell, and a figure the two readings disagree on is left out rather than guessed. A certificate covers one batch on one date. We have not tested these batches ourselves.
