Manufacturer / brand review
Particle publishes a searchable batch COA vault. Newer reports materially broaden the evidence beyond the historical GHRP-2 sample.
Inspected sample results
BPC-157 5 mg, batch 2026346, LYO-0739, published 3 September 2026: 6.38 ±0.03 mg; purity 99.2 ±0.5%; endotoxins 0.486 ±0.01 EU/mg; aerobic and yeast/mould counts 0 CFU/g. Seven reported elements are each <0.001 ppm. KPV 5 mg, batch 2026335, LYO-0310, published 13 July 2026: 4.64 ±0.02 mg; purity 99.2 ±0.5%; endotoxins 0.025 ±0.001 EU/mg; the same microbial and element panels. These are sample results, not guarantees or universal acceptable limits. Bioburden, endotoxin and elemental documentation each earn 3.75/5 across two dated reports; the other three categories earn zero.
Testing methods and purification
New Liquilabs reports include chromatographic purity, retention-time and spectral identity, MS, USP <61> microbial counts, USP <85> chromogenic endotoxins and a seven-element screen. Neither report establishes sterility, residual-solvent clearance or complete related-impurity characterization.
How often is testing performed?
The vault lists 91 documents, with visible publication groups in June, July and September 2026. We inspected July KPV and September BPC-157 reports in addition to the older GHRP-2 report. This demonstrates repeated publication, not an audited every-lot schedule.
What remains unverified
BPC-157 acceptable-range fields are blank. Report dates are publication dates; current delivered-vial matching and independent sample custody remain unverified. Older GHRP-2 endotoxin discrepancies remain unresolved.
Catalogue snapshot
Examples from the linked source, not a complete or real-time stock list. Institutional entries describe service categories. Shipping to Cyprus is not verified.
Why this score?
Points reward evidence maturity, not measured product purity. Claim-only points are limited; unknown criteria remain zero. Full rules are available in Research guidesBusiness decision guidesour methodology.
Verification limits
Lab attribution: Liquilabs (supplier-hosted reports). A laboratory-hosted record, where explicitly identified, was inspected on the lab’s portal. No direct staff confirmation, blind purchase, independent sampling or full current-batch audit was performed by Peptide.cy. Absence of a recorded test is not proof of contamination.
Public claims about purification cost, manufacturing location or certifications are not treated as proof of a clean final product. An authenticated COA would still apply only to its identified sample.
