To ensure their purity, identity, and quality, each product is subjected to independent laboratory testing by a third party. In order to guarantee consistency and transparency, the results of each batch’s meticulous analysis are documented in a Certificate of Analysis (COA).
Products should be kept in a cool, dry place away from heat, moisture, and direct sunlight. To help maintain stability and quality, containers should always be kept tightly sealed, and any specific storage instructions on the product label should be followed.
Depending on where you are, orders are typically processed within 24 to 48 hours and delivered within 3 to 7 business days. During peak times or when courier delays occur, delivery times may vary.
The Certificate of Analysis (COA) of each product batch can be used to verify the batch number. By confirming the purity, authenticity, and testing results of the product for that particular batch, this ensures transparency.
Only for products that arrive damaged, defective, or incorrectly, do we offer refunds or replacements. Please contact our support team with your order information within the specified return window to request a refund. After verification, approved refunds are processed.
