"Bolster nitric oxide levels and expand blood vessels"
L-arginine at 3-9g/day supports this in studies; actual dose in this product is unknown.
PubMed: L-arginine clinical trials -
"Clinically dosed formula with patented ingredients"
Proprietary blend hides all per-ingredient doses; cannot verify if amounts match clinical studies.

"$44.99 price for transparent, clinically dosed formula"
Standalone L-arginine (3-9g/day) costs $15-25 for 30 servings; serving size here not disclosed.
Consumer advice
- • Contact the manufacturer to ask for per-ingredient doses in the proprietary blend—if they won't disclose, that's a red flag.
- • Compare to standalone L-arginine (3-9g/day) or citrulline malate (6-8g/day) supplements, which are cheaper and transparent.
- • If you do buy, take it consistently for 4-8 weeks before judging results—nitric oxide boosters work slowly.
- • Stack it with actual training; no supplement replaces hard work.
Claims vs Evidence

"Clinically dosed formula"
Unsupported
Proprietary blend prevents verification of clinical dosing; marketing claim cannot be verified.
Based on: all ingredients
"Can be stacked with pre-workout for improved blood flow"
