Getting your US supply in record time

Ordering high-quality supplements from the US presents a logistical challenge for those living in Japan. Many US health stores do not offer direct international shipping to international addresses. Using a freight forwarder is the standard solution for obtaining these products quickly. You can shop us store options by using a tax-free us address in Oregon, which eliminates US sales tax. This method is the most efficient way to maintain your cognitive stack in 2026 without waiting for local distributors to restock.

Using proxy shopping for easier access

If a US store does not accept your local credit card, proxy shopping services can handle the purchase on your behalf. This "buy for me" approach ensures that you never miss out on limited-run batches of Momentous products.
