Every batch is analysed by an independent ISO/IEC 17025-accredited laboratory. Identity, purity, and mass-spec results are published on the product page before you buy.
Every batch is verified by an ISO/IEC 17025-accredited laboratory before release. Identity, purity, and documentation travel with the product — not behind a form.
Sensitive peptides ship in insulated cold-chain packaging with gel packs sized for a 48-hour transit window, tracked door to door.
Everything worth asking before you order.
Shipping, storage, quality, and when to speak to a clinician — without the runaround.
What proof of quality comes with my order?
Every batch ships with a batch code printed on the vial. The matching third-party certificate of analysis — identity, HPLC purity, and mass-spec results — is linked on the product page and also available from your order page after purchase.
Should I speak to a clinician before using a peptide?
We recommend it — especially if you are pregnant, nursing, managing a medical condition, or combining peptides with prescribed medication. Our product pages are educational. They are not medical advice and they do not replace a conversation with a qualified practitioner.
When will my order ship and arrive?
Orders placed before 14:00 CET Monday–Friday ship the same business day from our European fulfilment centre in The Hague, Netherlands. Standard tracked EU delivery arrives in 2–4 business days; express options are available at checkout.
