Our lab testLocked / 40Not tested yet
We have not sent a NextGen Peps product to an independent lab yet, so these 40 points are locked. The lab report will go on this page when we do.
Reviews2.4 / 20Low rating, few reviews
External review sites: ★ 3.1 ± 0.1 average, from under 50 reviews. We show a range because sites round their ratings differently.
That gives 2.4 of 20.
Community3 / 15Serious concerns raised
Forum and Reddit talk raises serious concerns. Nobody has left a review on Peptide Scanner yet.
That gives 3 of 15.
Certificates19.8 / 251 of 1 peptides covered
Publishing: 11.5 of 15. We hold 53 lab certificates from their website, naming Bioviridian and BioRegen. We found 0 of the 53 on the issuing lab's own website (not every lab has a public lookup). The one peptide we track has a matching certificate from an independent lab. 20 of the 53 certificates include a contamination test (endotoxin, sterility or heavy metals). 9 of 17 dated certificates were issued in the last 6 months; 4 are over a year old. Newest: Sept 2026 (6 weeks old). Oldest: Jul 2025.
Claims match: 8.3 of 10. Their own certificates against their claims: 7 of 12 measured vials are within 3% of the label (5 overfilled); 0 of 41 certificates fall below 98% purity.
Their claims against their certificates: 17 of 22 measured vials off label.
A certificate is the shop's own document. It is not our test.

Their certificates vs their claims

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.

NextGen Peps FAQ
Is NextGen Peps legit?
We score NextGen Peps 25 of 60, from reviews, community posts and the certificates they publish. We have not lab-tested them yet. The reasons for each part of the score are in the verdict above.
Does NextGen Peps publish lab reports (COAs)?
Yes. We hold 53 certificates from their website. They cover 1 of the 1 peptides we track. Labs named on them: Bioviridian and BioRegen. We could not find any of them on the lab's own website. A certificate is the shop's own document, not our test.
How much does NextGen Peps charge?
On 7 Nov 2026 we tracked 2 prices from $41 to $59. The cheapest is GHK-Cu at $41. The full list is in the price table above.
Where does NextGen Peps ship?
They ship to United States.
Has Peptide Scanner tested NextGen Peps?
Not yet. Lab results are worth 40 points, and those stay locked until we test one of their products at an independent lab.
