A certificate belongs to a batch, not to a product line. A result for one batch says nothing about another.

Storage and handling

Vials are packed to protect against damage in transit. Shipments are not temperature-controlled: they are not shipped on ice or refrigerated, and travel at ambient temperature, which is appropriate for lyophilized powder.

Shipping

Where we ship. We ship to the United States and Canada. Orders to Canada travel on an international service and may attract import duties, taxes or customs clearance, which are the recipient's responsibility. We cannot ship anywhere else at this time.

Processing. Orders are dispatched by the next business day after payment clears. Orders placed at a weekend or on a public holiday are dispatched the following business day.

Tracking. A tracking reference is provided by email once your order is dispatched.
