Methodology
How we grade
Lab results45%
How pure each vial was and how close it came to the labelled dose. Recent tests count more; a wrong peptide scores zero.
Strength of evidence25%
How many vials were tested, whether they were bought anonymously, and whether the reports can be checked.
Shop reputation30%
Starts at 100 and loses points for each problem we can source. Customer reviews never change a lab result.
Grade scale
- A90+
- B80+
- C70+
- D60+
- F<60
Evidence uses lower cut-offs, because anonymous purchases are rare across the market.
Limits on the overall grade
- Never higher than the lab-results grade.
- D at most if the shop can't be ordered from, has a critical problem or fails its lab tests.
- C at most if the evidence is very weak.
- No lab results means no grade.
Full scoring rulesPoints, caps and cut-offs behind each score
Lab results
- Each vial scores out of 100: half for purity, half for how close it was to the labelled dose.
- A wrong peptide scores zero, and costs the shop 1.5 more points for every 1% of vials affected.
- A vial that tests positive for bacterial toxins can score no more than 30.
- Recent vials count more than old ones. Reports the shop published itself count 50%.
- With only a few vials, we hold back: one perfect vial can't earn an A.
Strength of evidence
- How many vials were tested (up to 35 points).
- Whether they were bought anonymously, like a customer would (up to 20).
- Batch numbers, how recent the tests are, a lab report you can check, contamination tests and more than one lab (the remaining 45).
- Cut-offs: A 80+ · B 70+ · C 60+ · D 50+ · F 0+.
Shop reputation
- Starts at 100. Each problem we can source costs points: critical 35, major 20, minor 7.
- "Not reviewed yet" until we've checked, and then it doesn't count toward the overall grade.
- Customer reviews inform this score only; they never change a lab result.
What the lab grade means. A: Vials were the right peptide, very pure and close to the labelled dose. C: Results were mixed: some measurements missed the mark. F: Results often failed: wrong peptide, low purity or far-off doses.
Where the data comes from, and what we didn't doSources, the basic check, missing data, authorship
Lab data. Results come from independent lab records, each published with its lab report. We copy the measurements, link the report, and grade them ourselves; nobody else's rating is used. The data is refreshed at most hourly.
The basic check. A vial passes if it's the right peptide, at least 99.5% pure, and within 35% of the labelled dose. A vial missing purity or dose is marked "not enough data", never a pass.
Missing data and look-alikes. Missing values are shown as "not measured" or "not checked". Shops with similar names aren't combined unless a connection is documented.
What we didn't do. Unless a vial says otherwise, we didn't buy or test it ourselves, didn't confirm reports with the labs, and didn't contact the shop.
Authorship. This page is compiled automatically from lab data and hasn't been reviewed by an editor yet. We have no affiliate relationship with Peptide Maxxing and earn nothing from it.
Have evidence we should see? Lab reports with a batch number, order records or corrections can be sent through our contact page or to editorial@peptidevendorreviews.org.
The same rubric applies to every shop, and commercial relationships never change ratings, grades, rankings, or the selection of alternatives. Partner links are labelled. A grade describes the evidence on the date shown. It isn't advice to buy or avoid a shop, or a judgement on whether any peptide is safe or right for you. Rubric grading-v2 (2026-10-24).
FAQ

Is Peptide Maxxing legit?
No overall grade is assigned because the reviewed lab evidence is insufficient. No independent lab has tested anything it sells. We grade lab evidence and published facts; grades are not endorsements and do not determine whether a business acts lawfully.
