How PeptideJury works

A trust value is only useful if it stays traceable: which vendor identity was checked, where the signals came from, and how conflicting information is handled.

In short

How a Trust Score comes together

PeptideJury gathers public information about a vendor, has an AI organize that information, and adds experience reports from the community on top. All of that together produces a Trust Score.

Web search

An automated search sweeps forums, comparison sites and published reports for mentions of the vendor.

AI reads along

An AI reads the results, matches them to the right vendor, and records what is actually being reported - as individual, traceable evidence.

Community adds to it

Verified members report their own experiences, surface new vendors, and can confirm or correct existing evidence.

A score emerges

The Trust Score comes from all the reviewed evidence together - an ongoing summary, not a final verdict.

Good to know

A low score with little evidence isn't a verdict

When only a little evidence has been found for a vendor so far, the score can swing widely. That doesn't automatically mean the vendor is untrustworthy - it mostly means not much could be checked yet.

40Trust Score

Little evidence Β· For example, just 2 findings. The score can change quickly as more information comes in.

40Trust Score

Lots of evidence Β· For example, 40 findings. The score rests on a broader, more stable base.

The more reviewed evidence sits in the database, the clearer and more stable the results become for every vendor.

Why joining in matters

More reports help everyone

Automated web search doesn't find every vendor or every situation. Community experience reports help bring new vendors in in the first place, confirm existing evidence - or correct it once it no longer holds.

Report vendor experience

The Trust Score

A number from 0 to 100

The Trust Score summarizes how the information reviewed for a vendor so far turns out. A high value means mostly positive, well-evidenced experiences. A low value means mostly negative experiences or unresolved incidents. It's a snapshot, not a final verdict.

Making sense of ratings

Positive, neutral, negative

Positive

The experience went as expected or better - for example, on-time delivery and the correct product.

Neutral

Neither clearly positive nor negative - for example, a minor delay with no lasting downside.

Negative

Something genuinely went wrong - for example, non-delivery, the wrong product, or suspected deception.

From find to signal

Six steps, not a black box

01

Identify the vendor identity

Names, domains, handles, email addresses and other public identifiers are matched to the most specific vendor identity possible. Similar names alone are not enough to merge two vendors.

02

Collect sources

Publicly findable websites, forums, community posts and other permitted signals are captured as individual findings. The source stays attached to the evidence.

03

Review and merge

Matches are checked for relevance, duplicates and wrong attribution. Repeated copies of the same content should not count like several independent statements.

04

Document evidence provenance

For accepted evidence, the source, timing, brief context and traceable link to the vendor are stored. Members see more context than anonymous visitors.

05

Calculate trust

Positive, neutral and negative signals feed into the score together with their underlying data quality. A single value is meant to summarize the evidence, not hide individual claims.

06

Changes over time

New evidence can change the score. PeptideJury therefore treats reputation as an ongoing state, not a one-time, permanent verdict.

Data quality

Data quality and confidence are not the same as trust

A vendor can have a certain trust value while still resting on a thin data foundation. That’s why data quality and confidence are tracked separately. Few, conflicting or hard-to-attribute sources limit how much a value can say.

Public vs. member

Public output stays deliberately brief

Without logging in, VendorCheck shows only the vendor name, Trust Score and the number of underlying data sources. Verified members can see additional permitted identifiers, data quality and evidence context. Internal moderation or account data is never published.

Privacy & abuse protection

As little personal data as possible

Private account data stays private. Public community contributions are attributed to the public username, not to first name, last name, email or country. Reports, doxxing, harassment and manipulative mass-reporting are all subject to moderation and abuse protection.

Limits

A reputation platform, not a shop

PeptideJury is not a shop, not a purchasing or brokerage platform, and offers no medical advice. Trust signals describe existing reputation and data quality; they are not a guarantee of future behavior and not a recommendation to purchase, use or dose anything.

Traceability

Why a score can change

New sources, a corrected vendor attribution, removed duplicates or additional community evidence can change the Trust Score and the data quality. What matters is therefore not only the current value, but also that the underlying evidence stays checkable.
