The risk of seized packages and lost money

Belgian pharmacies often lack stock of US-specific formulations due to local EU regulatory delays. If you try to order directly from unauthorized third-party sellers, you risk losing €50 or more if the package is flagged by customs. To ensure your order arrives safely, using a reputable freight forwarder like comGateway provides a tax-free US address to collect your items before they are sent to Europe.

How to buy Momentous from US stores

Save €25 on retail markups by purchasing directly from US-based health sites rather than local resellers. To get started, you need to shop US store locations that carry the full Momentous line. You can buy from US ship to Belgium easily once you have your US suite number.

Avoid credit card declines with the BuyForMe service

Some US health retailers block international credit cards or automatically decline orders that use a known shipping hub address. This can lead to your funds being held for days in a pending state, causing unnecessary frustration. The BuyForMe service solves this by having comGateway purchase the item on your behalf using a US domestic payment method. This assisted purchase or proxy shopping method is the most reliable way to guarantee your order isn't cancelled. You can learn more about the BuyForMe service in our detailed FAQ.
