How are my allergen extracts shipped?
A reputable courier is used to ship overnight for all extracts. Extracts are packed and shipped in accordance with studies that have evaluated the stability of allergen extracts when shipped at ambient temperatures. These studies concluded that only temperature extremes, over a prolonged period, led to antigen degradation and a loss in potency, particularly with glycerinated extracts.
Should prolonged deviations occur during shipment, please reach out to the Customer Service Team to assess changes in potency. During the summer, ice packs can be included upon request, but these come at an additional cost and are likely not necessary.
