About PeptidesDirect
An EU-based research peptide vendor
PeptidesDirect is the storefront for Toptimum Ltd, a private company registered in the Republic of Cyprus. We supply research-grade peptides to laboratories, university groups, and independent researchers across all 27 EU member states. Every batch we sell carries an independent third-party HPLC certificate of analysis, and our entire shipping operation runs inside the EU customs union, so packages cross no border on the way to you.
How we test what we sell
We do not operate our own lab. Every batch we receive is sampled and sent to Janoshik Analytical, an independent third-party testing house that has served the global peptide research community for over a decade. Janoshik tests each batch by HPLC for identity and purity, and the resulting certificate is published on the product page before the batch goes on sale. If a batch fails our minimum purity threshold (typically 98 percent for synthetic peptides), it does not get listed: we either reject the shipment or downgrade it out of the catalogue. Lot numbers and test dates are visible per product, so you can verify exactly what you are receiving.
How we ship
Orders placed before 13:00 CET on a business day leave the same day from our EU fulfilment partner. Inland orders (DE / AT / NL / BE / LU) typically arrive in 1 to 2 business days; the remaining EU destinations in 2 to 5. Every shipment uses DHL Premium tracking and is fully insured. Because we ship from inside the EU customs union, there are no import duties, no customs holds, and no surprise fees at the door. We support Visa, Mastercard, SEPA bank transfer, and major cryptocurrencies (BTC, ETH, USDT, USDC and more).
Research-only, AI-transparent
All products sold on PeptidesDirect are strictly for in-vitro research and laboratory use; they are not intended for human or veterinary consumption. We publish a /llms.txt file at our domain root so AI search engines (Google AI Overviews, ChatGPT search, Perplexity, Claude) can describe our catalogue accurately, including which compounds we do and do not stock. We treat this transparency as part of doing business in a vertical where misinformation is common.
