Supplier documentation profile
Particle Peptides
Particle Peptides publishes a searchable, no-login COA vault with product names, batch numbers, test dates, current-status labels, and downloadable reports. The supplier describes a broader testing panel than chromatographic purity alone; report-level methods, laboratory provenance, acceptance criteria, and current-lot-to-vial traceability still require independent review.

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 9, 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 searchable public vault lists 91 downloadable records and exposes product, batch number, test date, file size, and current-status fields without requiring an account. | COA Vault |
| Lot traceability | Documented | The public vault connects named catalog products to batch identifiers and test dates. A match from those records to a received physical-vial label remains to be checked. | COA Vault + catalog |
| Laboratory provenance | Supplier-reported | Particle describes blind, independent third-party testing across multiple laboratories. The issuing laboratories and their relevant accreditation scopes still require report-level verification. | About page + COA Vault |
| Chromatographic purity | Supplier-reported | Product pages and the supplier's testing description report batch-level purity testing, but the full methods, chromatograms, integration rules, and acceptance criteria have not been reviewed across current inventory. | About page + sampled product page + COA Vault |
| Molecular identity | Supplier-reported | The supplier states that molecular identity is included in its third-party panel. Report-level spectra, method details, and acceptance criteria remain to be reviewed. | About page + COA Vault |
| Measured quantity | Supplier-reported | Particle states that peptide content is included in its testing panel. Representative lot-level calculations and the basis used for labeled vial quantity still require review. | About page |
| Contamination testing | Supplier-reported | The supplier reports bioburden, endotoxin, and class 1 and class 2 heavy-metal testing. Representative methods, numerical results, limits, and applicability to each current lot remain to be checked. | About page + COA Vault |
| Research-use positioning | Documented | Sampled product pages restrict the materials to scientific research and development and expressly exclude human, animal, drug, food, supplement, and cosmetic use. | Sampled product pages |
| Marketing consistency | Unresolved | Research-use restrictions appear alongside broad biological-effect summaries and consumer-commerce features. This review does not convert those claims into PDD conclusions, and referral destinations remain subject to page-level review. | Homepage + catalog + sampled product pages |

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
- Preserve and review representative complete current-lot reports across the stated analytical panel.
- Verify each issuing laboratory and the accreditation scope relevant to the reported method.
- Match a current vault record and catalog item to the identifier on a received physical vial.
- Record the identity, purity, content, bioburden, endotoxin, and heavy-metal methods, results, and acceptance criteria.
- Confirm whether the optional customer discount code will be created and what discount it provides.
