Contact

SemaxBuy operates as an online catalogue with orders placed and confirmed by message rather than through a checkout form. The fastest way to reach us for either an order or a technical question is Telegram.

https://t.me/semaxbuy is our primary channel for orders, purity questions, certificate-of-analysis requests and shipping updates. Messages are typically answered within one business day during Central European Time (CET) business hours, Monday to Friday.

Email

For anything you would rather put in writing outside Telegram — a formal withdrawal notice, a data protection request, or a documented complaint — write to orders@semaxbuy.com. Email enquiries are answered within the same one-business-day window where possible, and always within the timeframes set out in our terms of sale and privacy policy where those apply.

What to include

For an order or shipping question, include your order reference or the Telegram handle you ordered under. For a purity or certificate-of-analysis question, include the batch number printed on the vial label. For a withdrawal or return request, state clearly that you are withdrawing from the contract and include your order reference, in line with the procedure at /shipping-returns.

Response times

We aim to acknowledge every message within one business day. Order confirmations are typically sent the same or the next business day; data protection requests are handled within the statutory timeframe described in our privacy policy. All products referenced through these channels are supplied for laboratory research use only.
