FAQ

Most orders leave our warehouse within 3–7 business days, and delivery normally takes a further 5–7 days once the carrier has your parcel. You'll get a tracking email the moment it ships.

We ship worldwide. Customs procedures can add delays outside our control, and any import duties charged by the destination country are the recipient's responsibility.

Email support@biolgical.com with your order number and we will chase the carrier for you.

You get 20% off every delivery plus free shipping, on the schedule you choose. Each renewal charges your original payment method until you cancel. Full details: Subscription Benefits.

If a product is not doing what you hoped, you have 30 days from the day it arrives to tell us and we will refund you — opened products included. See the Refund Policy.
