JYM SS8 Review
- Excellent, well-rounded results across every category we measure
- Works through several different mechanisms rather than relying on one thing
- Simple once-daily routine
- A strong, comprehensive fat-burning and energy effect
- Real appetite/craving reduction
- Very high stimulant content
- Not a good fit for caffeine-sensitive users or those also taking a pre-workout
- Contains yohimbine, which can cause anxiety in some people
- Can be hard on an empty stomach for some -- best taken with a meal
