You are signed up for subscription…
You are signed up for subscription without being notified. Once notified, cancelled subscription and product still shipped and credit card charged. The product has not produced any visible results. The company does not provide a return shipping label. They sent me email with 30% off credit to keep the product or $50 credit towards future purchase. You have to pay for shipping and you have to provide proof of shipping and then wait for refund after they receive returned product and they will determine the refund amount. I don't recommend this product.
Response from Sun Coast Sciences LLCJun 30, 2026
Thank you for taking the time to share your experience, Cynthia. We're truly sorry that your experience with us fell short of your expectations. We understand how frustrating it is to receive an order you believed had been canceled, and we're sorry for the confusion and disappointment this caused.
We also understand that subscriptions can feel unexpected. Our subscription program is always optional, and customers can choose either a one-time purchase or a subscription during checkout. That said, we recognize it's easy to miss this when placing an order, and we're sorry if this wasn't as clear as it should have been. Customers can update, pause, or cancel their subscription at any time through their secure customer account or by reaching out to our support team for assistance.
Because we work hard to process and ship orders as quickly as possible, there are times when an order has already entered fulfillment before a cancellation request is received. While we're sorry this happened in your case, we want to reassure you that every purchase is still covered by our 365-day satisfaction guarantee, so you're never stuck with a product you don't want.
We're also sorry to hear you didn't see the results you were hoping for. We know how disappointing that can be, and we understand your frustration.
Regarding the return process, we know paying for return shipping can feel like an inconvenience. Since we provide free shipping on all outgoing orders, customers are responsible for return shipping if they choose to send products back. To help make things easier, we often offer no-return solutions, such as partial refunds or store credit, for customers who would rather avoid the hassle of shipping an item back. If a customer prefers a refund instead, that's absolutely an option as well. Once return tracking is provided, we issue the refund right away. If tracking isn't available, the refund is processed as soon as the return is received and checked in by our warehouse.
Cynthia, we're genuinely sorry this was your experience. We'd truly appreciate the opportunity to make things right. If you reach out to us directly, our team will be happy to review your account, answer any remaining questions, and work with you to find the solution that leaves you feeling completely satisfied. Your happiness means a great deal to us, and we'd love the chance to restore your confidence in Sun Coast Sciences.

So far I am loving it, still alittle early for better results.
Response from Sun Coast Sciences LLCJun 29, 2026
Thanks so much for sharing your experience! It’s great to hear you’re already enjoying the product.
You’re still early in the process, so it’s completely normal for results to build gradually over time. We really appreciate you giving it a fair try, and we’re here if you ever have any questions or need a hand along the way.
Looking forward to hearing how things continue to go for you!
