The hacks
Build stacks around achievable health goals
"Support better sleep" is achievable. "Cure insomnia" is not. Stack claims must amplify what the products can do, not invent outcomes. Realistic goals refund at 7%. Miracle promises refund at 20%.
Goal-specific stacks with complementary logic
Sleep stack: magnesium (relaxation) + melatonin (onset) + L-theanine (quality). Each product addresses a different aspect of the goal. Tiergain structures goal stacks where every product has a clear role.
Include a dosing guide with every stack
A printed card: "Morning: B12 + Iron with breakfast. Evening: Magnesium + Melatonin 30 min before bed." Customers who follow the protocol get better results. Better results mean fewer returns.
Set realistic timelines on every stack page
"Most customers notice improvement in 2-3 weeks." This sets the expectation. Without a timeline, customers expect results in 3 days and refund on day 5. Honest timelines prevent premature returns.
Trial-size first purchase to prevent full-size regret
Offer a trial-size stack first. Full-size refund rate after a trial: 4%. Full-size refund rate without trial: 20%. The trial eliminates the mismatch before the big purchase happens.
Day-7 check-in to reinforce usage and prevent returns
Day 7 after delivery: "How is the sleep stack going? Here is what to expect in weeks 2-3." The check-in reinforces commitment, sets week-2 expectations, and catches issues before they become returns.
Your offer can amplify value but not invent value
A stack that promises "support better sleep" delivers on that promise when it contains the right ingredients. A stack that promises "guaranteed deep sleep every night" delivers disappointment. The claim determines the refund rate.
