Everything you need to know about shopping with ProteinCo
How do I determine the right size for my order?
We provide a detailed size guide on every product page. Since our fashion lines range from slim-fit to oversized, we recommend measuring a similar garment you own and comparing it to our specifications for the perfect fit.
What is your return policy for apparel?
We offer a 30-day return window for all unworn and unwashed items with original tags attached. Simply visit our returns portal to generate a prepaid shipping label.
How long does shipping take?
Standard shipping typically takes 3-5 business days within the continental US. International orders may take 7-14 business days depending on the destination and customs processing.
