Consumer advice
Do not use this product expecting sexual performance benefits—human clinical evidence does not support this use. If you have erectile dysfunction, consult a doctor; prescription options (sildenafil/Viagra) have proven efficacy. If interested in herbal approaches, discuss with your healthcare provider first, as horny goat weed carries documented risks of muscle damage, neurological effects, and kidney injury. The $19.89 price for 90 tablets ($0.22/tablet) is reasonable for a supplement, but you're paying for an unproven product with safety red flags.
