PepIndex score
42.7 / 100
2.1/ 5Thinly documentedData coverage
45%
Coverage is the share of scored fields we hold and corroborated for Xcel Peptides. A score built on a handful of unchecked claims and a score built on forty verified data points are not the same finding, so both numbers are always published together. How coverage is computed.
Is Xcel Peptides legit?
Read the record first. PepIndex holds 1 regulatory or enforcement action on file against Xcel Peptides, alongside 0 certificate records, and scores it 42.7/100 on 45% data coverage.
- An authority action is publicly verifiable and cannot be manufactured, which is why it weighs more here than any review.
- Its certificates can be read without an account, so anyone can check these figures.
- On the business side it publishes a named legal entity, a postal address and prices visible without an account.
What this does not tell you
- PepIndex has located no independent customer reviews for Xcel Peptides, so nothing here speaks to its service or fulfilment.
- A score measures what a vendor publishes about its testing and its business. It does not measure the contents of any vial a buyer actually receives, and PepIndex does not commission its own assays.
Certificate recordsLot-level results with labeled versus assayed mass0 lotsView all →Hide ↑
Discrepancy is computed as the absolute difference between labeled and assayed mass, divided by the labeled mass. A vendor-published certificate is a claim; only an independently commissioned assay is treated as corroboration.
No certificate records are indexed. Either none are published, or those published could not be read without an account.
Recorded data pointsEvery field with its source, capture date and whether we corroborated it6 verified3 claimed10 not recordedView all →Hide ↑
A tag of verified means we opened the cited source and confirmed the value; published means we recorded the vendor’s own published information, taken at face value. Both count in full; only a value with no checkable source earns nothing. Fields older than 30 days are marked stale.

- Certificates are readable publicly, without an account
- Operates under a named legal entity (Xcel Research LLC)
- Publishes a physical postal address
- Prices are visible without an account
- Retains historical certificates for comparison over time
Weaknesses
- Publishes 6 certificates on its own site, none of which this index has been able to read and record
- Testing laboratory is not named on the certificates read
- No ISO/IEC 17025 accreditation recorded for the testing lab
- No independent third-party reviews located
Regulatory & enforcement record
Authority actions on record against this vendor. Issued by regulators and publicly verifiable — unlike self-reported reviews, these cannot be manufactured, which is why they, and not reviews, drive the track-record score.
- Warning letterFDA · 2024-12-10
The FDA warned Xcel Research LLC (xcelpeptides.com) that products it offered for sale, including Retatrutide, Semaglutide, Cagrilintide, Mazdutide, Survodutide, and Sermorelin, are unapproved new drugs sold in violation of FD&C Act sections 505(a) and 301(d).

How this score was calculatedEvery signal, its weight and the arithmetic — reconstructable by handrubric v1.11.0View calculation →Hide ↑
Each criterion is scored out of 100 over the signals we could assess, then weighted into the overall figure. Within a criterion, a signal contributes weight × merit × credit: merit is how good the recorded value is, credit is what its provenance earns — 1.00 for a value with a checkable source, 0 for a value recorded without one. A missing signal counts as a partial gap — half its weight — so a vendor that publishes what others leave blank scores higher, while a blank still costs; a value recorded without a source counts in full and earns nothing, so omitting one can never raise a score. A criterion with no data at all — track record when no independent reviews are locatable — is set aside and the remaining weights renormalised; the coverage figure, shown alongside, reports how complete the assessment is.
