I'm seeking licensed urologists, endocrinologists, sexual health specialists, functional medicine practitioners, or registered dietitians to provide insight on a dietary supplement formulated to support male sexual performance, libido, stamina, and erectile function. Specifically, I'm looking for expert opinions on the effectiveness and safety of ingredients such as L-arginine, maca root, ginseng, Tribulus terrestris, horny goat weed, zinc, and other herbal extracts (as commonly found in formulations like Power X). We’d love to include your professional opinion on: How these ingredients work individually or synergistically to improve blood flow, nitric oxide production, and sexual performance Whether such supplements meaningfully support libido and erectile function in men with mild to moderate concerns Potential side effects, contraindications (e.g., cardiovascular conditions, blood-pressure medications)
