particlepeptides.com · Lucenec, Slovakia · every fact below was read off the company's own live site on 8 September 2026.
The most detailed testing disclosure we found anywhere in the category, and the only EU-based supplier here, with a registered company name and address on the page.
What works
- Endotoxin, heavy metals and bioburden testing named individually, which almost nobody else in this category commits to in writing
- A registered company name and a registered address, not just a country
- The only supplier on this page shipping from inside the European Union
What does not
- No free-shipping threshold and no delivery window published on the pages we reviewed
- Shipping into the United States from the EU adds customs exposure that domestic vendors do not have
- No published phone number and no stated support response window
What they sell
A mid-sized research catalogue organised by research area — longevity, metabolic, muscle, cognitive — with ipamorelin, GHK-Cu, CJC-1295, AOD-9604, KPV, semax, selank, epithalon and melanotan 2 among the listed compounds, plus bacteriostatic water. Products are described as intended for scientific research and development purposes only.
The distinguishing feature is not the catalogue but the origin. This is the only supplier on this page shipping from inside the European Union, which makes it the obvious first stop for a European buyer and an awkward one for an American, for the same reason.
Testing and certificates
This is the most detailed testing disclosure we found anywhere in the category. The company states that it provides independent analysis of purity, identity, peptide content, endotoxin content, heavy metals of class 1 and class 2, and bioburden — for all of its products, not a sample — and operates a COA Vault for retrieving the certificates.
Endotoxin, heavy metals and bioburden are the three tests most vendors quietly leave out, and naming them individually is a commitment that would be uncomfortable to make falsely. It is the only five-out-of-five on testing we awarded other than Oath Research, and it is earned on a different basis: breadth of panel rather than a remedy behind it.
Shipping, payment and support
This is where the score falls away. No free-shipping threshold, no carrier and no delivery window are published on the pages we reviewed; shipping from an EU country is stated as a feature, with the detail held on a separate policy page. Payment is described as secure online card payments, again with the specifics on their own page.
Company identification, by contrast, is the best on this page: PARTICLE s.r.o., Kolonada 4490/18, Lucenec 984 01, Slovakia — a registered entity with a registered address, not a country badge. The company states ten years on the market and runs a public affiliate programme paying ten percent, in euros only. There is no phone number and no stated support response window.
Why it places where it does
Fifth, tied on score with Core Peptides and placed just behind it because a US buyer ordering from this page is more likely to be served by a domestic shipper than by a better-documented one across a customs border. For a European buyer that tiebreak runs the other way, and Particle Peptides is comfortably the best option on this page.
If the company published a shipping policy with the same precision as its testing panel it would be in the top three. The gap between those two disclosures is the strangest thing about the site.
