Pros
- Firestorm delivers intense euphoria, energy, and a fast come-up, with some users experiencing significant performance boosts.
- It is highly recommended for individuals who specifically seek pre-workouts containing DMHA and DMAA.
- Many users find it to be a very strong and effective stimulant, even at low doses.
Cons
- A drawback of Firestorm is that some users report a 'dirty stimulation' feeling, characterized by a mentally high sensation, strong adrenaline, but poor dopamine effects, potentially due to ingredients like DMAA.
- Some individuals experience unpleasant side effects such as cold hands, runny nose, and tearing eyes, suggesting the presence of yohimbine-like compounds.
- Effects can be inconsistent, with some users reporting feeling absolutely nothing despite the strong ingredient profile.
- Experienced users accustomed to other high-potency pre-workouts may feel that something is missing or that a full 10-gram serving is necessary to achieve desired effects.

- Some users have experienced a milder effect than anticipated, followed by post-workout crash and anxiety.
- Flavor is described as only "Ok," and the overall experience may not always live up to the bold claims or user expectations, with some effects like euphoria/focus being mild.
