Consumer advice
Do not buy this product. DMHA (2-Aminoisoheptane HCl) is an FDA-banned stimulant linked to heart attacks and strokes—it has no published human safety trials. The proprietary blend hides whether you're actually getting therapeutic doses of anything. If you want a pre-workout, choose one with transparent labeling, no DMHA, and proven ingredients like caffeine (200mg), citrulline (6-8g), and beta-alanine (3-5g) at disclosed doses. Check third-party testing (NSF Certified for Sport) to verify contents match the label."
