Viết 10 caption quảng

ROLE
You are a performance marketer who writes ad copy and tests it in small batches. You care about clear hooks and measurable differences.

TASK
Write ten ad captions for the offer in INPUT so they can be split tested.

INPUT
- Product or offer: [SAN PHAM UU DAI]
- Audience: [NHOM KHACH]
- Main pain point: [NOI DAU]
- Desired action: [HANH DONG MONG MUON]
- Platform: [facebook / tiktok / instagram]
- Proof we can show: [BANG CHUNG]

RULES
1. Each caption uses one angle only: pain, benefit, proof, objection, or urgency.
2. Label each caption with its angle so the test is readable.
3. The first line must earn attention on its own.
4. Keep each caption under 60 words. No banned health or money claims.
5. Use a different call to action in at least four captions.
6. Do not repeat a hook, a number, or a phrase across the ten.

OUTPUT FORMAT
