About Particle Peptides
Established (~11-yr domain) Slovak EU vendor, PARTICLE s.r.o., that attaches a real per-batch independent COA from named lab Liquilabs to every product, covering purity, identity, content, endotoxin, heavy metals and bioburden to Ph. Eur. standards. Two opened COAs confirm BPC-157 97.8% and TB-500 99.1%; fully identified, ~4.5-4.9 review record, bank/crypto only.
Score overview
How we score →Weighted composite across 8 criteria; the letter grade follows our published bands and integrity gate.
Key facts
Pros
- Genuine per-batch, per-product independent COAs from a NAMED third-party lab (Liquilabs s.r.o., Czechia), one click from each product page, covering HPLC purity, identity, peptide content, endotoxin, heavy metals and bioburden to European Pharmacopoeia standards; two opened certificates (BPC-157 batch 2025297 at 97.8%, TB-500 batch 2025289 at 99.1%) confirm real, recent data that even reports below-label values honestly
- Fully transparent and established: real legal entity PARTICLE, s. r. o. with Lucenec address, phone and email, explicit research-use-only labeling, published terms/return policy, valid HTTPS, ~11-year-old domain (created 2015), Trustpilot 'Excellent' (~4.5/5) plus 4.9/332 on-site, and active warnings against cloned/impersonator sites
Cons
- Entire testing program depends on ONE relatively new lab, Liquilabs s.r.o., which was publicly alleged on Reddit to be a 'shell company'; the vendor rebutted this and cited cross-validation by Eurofins and Apigenex, but no Janoshik/Eurofins COA is actually published for the mainstream catalog, and independent purity sits at ~97-99% rather than >=99% across the board
- No credit-card payment (bank transfer + crypto only, so limited buyer recourse) and the policy explicitly states packages seized by customs or otherwise undeliverable are NOT reshipped (refund only); some on-site reviews report a broken QR/payment step; Semaglutide is not carried (closest GLP is 'GLP-3'/Retatrutide)

When was this Particle Peptides review last updated?
This grade was last reviewed on 2026-07-04 under methodology v1.0.
One of the more credible EU research-peptide vendors: a fully-identified Slovak company on an 11-year domain that publishes a genuine, recent, per-batch independent Liquilabs COA (full Ph. Eur. panel) for each product, with two opened certificates confirming 97.8-99.1% purity. Main caveats are that all testing rides on a single, relatively new lab (Liquilabs) that drew a rebutted 'shell company' Reddit allegation, no card payment, and no reship on seized parcels.
