True Peptides
True Peptides provides a searchable COA interface and detailed descriptions of expected lot documentation. The embedded database did not expose a sample certificate during this text-based review, so several testing claims remain supplier-reported.

Procurement details
Business policies not yet documented
PDD has not yet preserved dated, directly reviewable records for this supplier's ship-from location, regions served, processing time, free-shipping threshold, payment methods, or refund and replacement policy. We do not infer those details from a storefront location or checkout availability.
This section will expand into field-level records as eligible supplier policies are documented.
Evidence ledger
What the reviewed records support
Evidence and COA records last reviewed September 6, 2026. Missing documentation remains visible and is not converted into a negative claim.
| Review field | State | Finding and limitation | Basis |
|---|---|---|---|
| Public COA access | Documented | A public certificate database can be searched by lot number or product name without a stated account requirement. | COA database page |
| Lot traceability | Supplier-reported | The supplier says documentation is specific to the lot shipped, but a populated record was not preserved from the embedded database in this pass. | COA database + FAQ |
| Laboratory provenance | Supplier-reported | The supplier describes testing as independent. A named issuing laboratory and separate verification path still need to be recorded from a current report. | COA database description |
| Chromatographic purity | Supplier-reported | The site says full HPLC chromatograms and purity data are available for every lot; a sample chromatogram remains to be reviewed. | COA database + FAQ |
| Molecular identity | Supplier-reported | The FAQ lists mass-spectrum data as molecular-identity evidence, but a current sample spectrum was not available in the extracted record. | FAQ |
| Measured quantity | Unresolved | No public statement reviewed here established quantitative peptide content for every lot. | Public pages reviewed |
| Sterility testing | Unresolved | No lot-matched sterility result was located during the initial review. | Public pages reviewed |
| Endotoxin testing | Unresolved | No lot-matched endotoxin result was located during the initial review. | Public pages reviewed |

Evidence definitions
Documented
Connected to a directly reviewable public record.
Supplier-reported
Stated by the supplier but not independently confirmed.
Unresolved
The records reviewed do not support a conclusion either way.
Contradicted
Available records or statements materially disagree.
Open verification work
- Export one current certificate from the embedded database and preserve the complete report.
- Verify the issuing laboratory and report identifier independently.
- Confirm whether quantitative content, sterility, and endotoxin testing are performed by lot.
