Before buying either option
1. Define the goal
Choose one measurable reason for trying it rather than adding a product “just in case.”
2. Compare like for like
Check active amount, form, serving size, testing and daily cost.
3. Review after a set period
Avoid changing several products at once, and stop if adverse effects occur.
