Shipping Update

We are now seeing improvements in our shipping times. However, things are not yet back to normal and there are still some delays occurring.

Our normal shipping time averages 1 - 2 weeks. Shipments may potentially take an additional 2 – 4 weeks to arrive, depending on the source country of your order. Shipments from the United Kingdom and Canada are generally quicker than from other countries.

Please note that these times are averages and individual shipping times will vary. We highly recommend that you place your order at least 2 – 4 weeks or more ahead of your normal reorder time to avoid running out of your medication.

These delays are temporary, and we thank the shipping and delivery personnel who are working hard for all of us during this global crisis.

Please Note: We have resumed our normal 30-Day Shipping Guarantee. We will provide updates as the situation changes.
