Prices are normalized for comparison; checkout shipping, tax, inventory, and promotion eligibility can still change the final amount.
Movement compares modeled effective prices for the same exact offers in both periods. Tracked-offer changes require observations at both endpoints and do not influence the median change.

Public reputation signals are directional. They are not laboratory evidence and are not silently converted into product-quality claims.
Independent origin evidence and brand-confusion scan
Dated origin timeline
- Domain registeredRegistry RDAP
- First TLS certificate loggedCertificate Transparency
These sources are independent of each other and of the vendor: a registrar transfer cannot rewrite Certificate Transparency logs, and neither can edit the Wayback Machine.
Registered lookalike domains
No registered lookalike domains were found in the bounded permutation scan.
Corporate identity
State-registry verification has not yet been performed for this vendor — recorded as an open coverage gap below, not as a clean result.
What deserves a closer look
Deterministic diligence prompts; not an overall vendor, product-quality, or safety rating. A review label identifies a diligence gap or pending PB review; it does not establish misconduct or product quality.
Pricing visibilityReview
The pricing lane is critical; checkout values may have changed since PB's last accepted observation.
Certificate traceabilityCurrent signal
28 of 28 certificate origins resolve through exact provider-controlled routes (100%).
Product attributionCurrent signal
13 of 13 observed products have attributable certificate coverage (100%).
Public-signal reviewReview
1 domain or reputation change event await editorial review. This is a review queue, not a finding of misconduct.
Evidence continuityWatch
At least one accepted pricing or testing-evidence lane is not current.
Brand confusionCurrent signal
No registered lookalike domains were found in the bounded permutation scan.
What was checked — and what was not
Swept
- Certificate Transparency logsvia certspotter (unexpired certs only — floor, may understate age)
- Wayback Machine capture history
- Registered lookalike-domain scan (bounded permutation set)
Not swept
- Trustpilot public profilefeed unavailable
- State corporate registrymanual verification not yet performed for this vendor
- Reddit / forum sentimentnot systematically swept; community reports reach PB through the moderated intake queues
- BBB / consumer-complaint databasesnot systematically swept
A source listed as not swept means exactly that: PB makes no claim either way about what it would show. Silence is never presented as a clean result.

What this report does not establish
PeptideBenchmark aggregates public evidence and does not independently test physical products. Domain registry signals are operational metadata, not a finding of misconduct or product quality. Affiliate relationships are disclosed but never increase benchmark or testing scores.
