Caffeine
A high-evidence stimulant for alertness and exercise performance when dose and timing are controlled.
Evidence file
Mechanism, dose, form, limitations, related products, and PubMed-supported references are reviewed before this ingredient is used in stronger product copy.
Evidence summary.
- Mechanism
- Caffeine primarily acts through adenosine receptor antagonism, supporting alertness and reducing perceived effort for many users.
- Human Evidence
- The ISSN position stand supports caffeine as an evidence-backed ergogenic aid across multiple exercise contexts, with individual tolerance and timing as major variables.
- Dosing Context
- Effective ranges are individualized. WRAITH treats caffeine as a disclosed active, never hidden inside a proprietary energy blend.
- Form Standard
- Caffeine amount, source, and stimulant context should be clear on the label.
- Limitations
- Late caffeine can impair sleep. More stimulant is not automatically better performance.

ProductIgnite
Ignite is the WRAITH pre-workout: pump, energy, focus, and intensity. Most of the formula is mechanism-clean. Beta-alanine is retained with an honest caveat: its true ergogenic mechanism is chronic saturation, not one-scoop magic.
