How is purity verified?

Every Synava batch is independently tested by a third-party EU laboratory using HPLC-UV at 220 nm as the standard method. Selected batches and novel compounds also undergo mass spectrometry confirmation to verify molecular identity.

The minimum purity threshold is ≥ 99%. Each batch ships with a full certificate of analysis including the raw chromatogram — not just a typed purity number.

Which laboratory tests your batches?


We work with Liquilabs s.r.o., an ISO 17025-accredited analytical laboratory based in the Czech Republic. They perform identity verification, purity assay, endotoxin testing, heavy metals screening, and bioburden analysis.

You can verify any Synava batch independently by entering its batch number into our COA Vault.

What does "real chromatograms" mean?


Most peptide vendors provide a typed certificate listing a purity percentage. We provide the raw HPLC chromatogram graph that backs that number — the actual data output from the instrument, including peak retention time, baseline noise, and any minor impurities.

This means you can independently assess our analytical quality, not just trust a number on a PDF.

Are heavy metals and endotoxins tested?

Yes. Every batch is screened for heavy metals (class 1 and class 2 per European Pharmacopoeia) and endotoxins (LAL method). Results are documented on each COA.

Typical results: heavy metals not detected, endotoxins < 0.5 EU/mg.

How fast do you ship?


Orders placed before 14:00 CET on weekdays ship the same day. Orders after 14:00 ship the next business day.

Typical EU delivery times: Czech Republic 1 day, Germany/Austria/Slovakia 1–2 days, Western Europe 2–3 days, Northern/Southern Europe 3–5 days.

What payment methods do you accept?

We accept Visa, Mastercard, and bank transfer (SEPA for EU customers). Cryptocurrency payments (Bitcoin, USDC) are also supported through our payment partner.

All transactions are processed through PCI-compliant infrastructure. We never store your card details.
