Product and ingredient questions
Ask brand support for the current Supplement Facts label, ingredient amounts, allergen details, directions and warnings. Do not email sensitive medical records. A qualified healthcare professional should answer personal medical or medication questions.
Order and payment questions
Have the purchaser name, order email and BuyGoods order number ready. BuyGoods processes payment, so billing questions may need to be handled through the contact information in the receipt.
Shipping and tracking
Use the verified support contacts above for an address correction, tracking question, delayed package or damaged delivery. Contact support as soon as possible if the address is wrong.
Returns and refunds
Request current return authorization and instructions before mailing a product. Review the ColestZen refund details, including the customer-paid return-shipping term and deadline ambiguity.
Website questions
For a question about content on colestrzen.com, use the same email and identify the page and statement involved. Do not send card details through email.
