Overview
•High caffeine content (250mg) may cause jitteriness or insomnia in sensitive individuals; safe for most adults under 400mg daily limit per FDA guidelines.
•Beta-alanine at 3.2g can induce harmless tingling (paresthesia); no serious risks at this dosage supported by studies on PubMed.
•No major drug interactions for core ingredients, but caffeine may amplify effects of stimulants or interact with MAOIs; consult physician if on medications.
•Not recommended for pregnant/nursing women, children under 18, or those with heart conditions due to stimulant profile; low risk for healthy adults.
•Potential mild GI upset from citrulline malate or taurine in sensitive users; allergen-free formulation with no nuts, dairy, or gluten reported.
•Long-term use safe at recommended dosing, but cycle caffeine intake to avoid tolerance; quality assured by GNC's third-party testing.
