Pros
- Barbarian delivers strong, effective results, often described as a 'hitter' that 'slaps' and helps power through intense workouts like leg day.
- Users appreciate its stimulant profile, particularly the 'immaculate DMBA bubble' and the combination of DMHA and DMBA.
- It is often preferred over other Dark Labs products and is considered one of their best offerings, especially the original batches.
- The product can be effectively stacked with other supplements for enhanced effects.
Cons
- A drawback of Barbarian is the perceived inconsistency in quality and formulation across different batches, with newer versions often being less potent than the original runs.
- Some users report that newer batches can have short-lived effects, 'fizzling out' quickly, leading to an uneasy feeling and crash without significant positive effects.
- There is user dissatisfaction with Dark Labs' 'copy and paste labels,' suggesting a lack of transparency or innovation in product development.
