"I built every formula in this lineup. If something isn't working for you, I want to know. If something is, I want to know that too — your data is what makes the protocol better."
doc@thelongevityedge.comCommon Questions
Before you message — here are the answers Doc gets most often.
How do I skip my next shipment?
Sign in to your account → Subscriptions → "Skip next" on the subscription you want to push back. The change is instant. You can also change frequency, quantity, or pause entirely from the same screen.
Can I cancel a subscription anytime?
Yes. Sign in → Subscriptions → "Pause / Cancel." No phone tree. No customer-retention friction. We don't lock anyone in.
Do these supplements interact with my prescription medications?
Always check with the physician who manages your prescriptions — they know your complete medical picture, and a quick interaction check takes a pharmacist about thirty seconds. The most common interaction concern across the lineup is fish oil with blood thinners (warfarin specifically). Send Doc a message if you want to talk through which supplement is appropriate for your situation.
What's the money-back guarantee?
30-day money-back guarantee on every order. If a formula isn't right for you, email doc@thelongevityedge.com within 30 days and we refund the order. No phone tree.
Where do you ship? How long does it take?
We ship across the US (typically 2–5 business days) and to select international destinations (typically 7–14 business days). Free US shipping on orders $99+.
Where are your supplements manufactured?
All formulas are manufactured in the USA at GMP-certified facilities. Every batch is third-party tested for purity, potency, and (where relevant) oxidation. Certificates of analysis are available on request.
