Frequently asked questions

How does ordering work?

Add products to your cart and leave your name and phone number at checkout. Nothing is charged online. A Synthos representative calls or messages you within 24 hours to confirm the order, and you pay once you're happy with it.

How can I pay?

Visa or Mastercard, bank transfer, and local methods such as MB WAY and Multibanco in Portugal. Your representative sends the payment details after the confirmation call.

Where do you ship, and how long does it take?

We ship worldwide from inside the European Union, always with tracking. EU orders have no customs or import fees and usually arrive in 2–5 working days. Outside the EU, delivery usually takes 5–12 working days, and any local import duties depend on your country; your representative will confirm this on the call.

Is the package discreet?

Yes. Orders go out in a plain box with no product names on the outside.

How do I know what's in the vial?

Every lot is tested by an independent laboratory, and the certificate of analysis for your lot comes with your order. Ask your representative if you'd like to see it before you pay.

Are these products for human use?

No. Synthos products are sold for laboratory research only. They are not medicines and are not approved by the EMA, FDA or any other regulator for human use.

Can I order several products at once?

Yes. Add everything to one cart. Your representative will confirm the total, including any multi-unit price, on the call.

Can I cancel?

Yes. Since you only pay after the confirmation call, you can change or cancel your order on that call at no cost. See our terms for returns after delivery.
