Since we deal primarily with dietary supplements, orders can be exchanged or returned a maximum of 5 working days after receipt. The products that are returned must be unopened and in the (undamaged) original packaging. Sportswear may be fitted, but NOT worn on the skin. If you are going to try on a Muscle Concepts T-shirt, wear a thin T-shirt below so that the new T-shirt does not come into contact with the skin. We are very strict about this for hygiene reasons. Note: We have our own “microscopic detective professor” checking this out!

  1. Products held longer than 5 business days from receipt.
  2. Products whose packaging has been opened.
  3. Products that have been worn on the skin and contain odor or stains.
  4. Products that have been used, damaged or are incomplete.
