Why We Reviewed Tiger's Blood in Depth
Most pre-workout reviews just list ingredients and say whether they felt it. We wanted to go deeper — what does the peer-reviewed research say about each compound? What doses are supported by evidence? How does Tiger's Blood stack up against the published literature?
Full Ingredient Analysis
1. Caffeine Anhydrous
Caffeine is the most researched ergogenic aid in sports science. A dose-response relationship is well established: research shows peak performance benefits at approximately 3–6 mg/kg bodyweight. Cognitive benefits (focus, reaction time) are reliably observed across hundreds of RCTs.
2. Citrulline Malate
The nitric oxide precursor with the strongest research base. L-Citrulline is converted to L-Arginine in the kidneys, increasing NO production and vasodilation. The malate form in Tiger's Blood adds a Krebs cycle intermediate that may support ATP production. Research: Bendahan et al. (2002), Pérez-Guisado & Jakeman (2010).
3. Beta-Alanine
Beta-alanine raises intramuscular carnosine — a dipeptide that buffers hydrogen ions during high-intensity work. The tingling (paraesthesia) is benign and dose-dependent. Meta-analyses confirm benefits for exercise in the 1–4 minute high-intensity range. Research: Hobson et al. (2012), Saunders et al. (2017).
4. Alpha-GPC
Alpha-glycerylphosphorylcholine is the most bioavailable choline source for supporting acetylcholine synthesis. Research shows cognitive performance benefits and pilot data suggesting short-term growth hormone release. Research: Ziegenfuss et al. (2008).
Verdict
