COVID-19 SERVICE UPDATE – JULY 2021
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. We will provide updates as the situation changes.

Our normal shipping time averages 1 - 2 weeks. Due to the pandemic, shipments may sometimes 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.

We offer a shipping guarantee when you place an order with us. If your order does not arrive within 6 weeks from the date it was shipped, we will re-ship your order to you at no additional cost.
