Shipping to United States
Most domestic vendors ship 2–5 business days via USPS or UPS. Prescription compounds (modafinil, armodafinil) require a US prescription; international ordering of scheduled substances is a federal-level enforcement issue.
Customs and import notes
US Customs and Border Protection routinely intercepts unscheduled bulk powders from overseas vendors, particularly racetams in larger quantities. Personal-use quantities of clearly-labelled supplements from regulated jurisdictions generally clear without issue. Schedule IV substances (modafinil) imported without prescription face seizure and potential controlled-substances enforcement.
Import responsibility: You — not the vendor — are responsible for ensuring that the substance you order can legally enter United States. Vendors typically state their shipping policy but cannot guarantee customs clearance in every jurisdiction; refunds for seized parcels are rare. If you have any doubt about Spirulina’s status in United States, do not order until you have verified with a pharmacist, customs broker, or qualified clinician.

Prices in USD
Prices in our vendor table are shown in USD. To convert to USD ($), use the live FX rate at checkout — vendors typically charge in their local currency and let your card handle conversion, or in USD directly if the vendor maintains a United States storefront.
For shipments from outside United States, factor in (a) shipping cost (commonly USD 10–25 international standard or USD 25–55 express), (b) customs VAT/duty (commonly applied above a national de-minimis threshold), and (c) any payment-network FX margin. The cheapest sticker price in the table is rarely the cheapest landed cost once these are added.
