⚡ Quick AnswerLast Reviewed: October 2026
These products target different things. VigRX Plus is our top pick among male sexual-health supplements; Semenax is our top pick among semen-volume supplements. Each has one small published placebo-controlled trial of the product. Choose by goal.
VigRX Plus is not a treatment for erectile dysfunction; see a doctor about persistent symptoms.
⚡ Quick Verdict
Pick by goal rather than by a winner. VigRX Plus's trial found better erection scores than placebo over 12 weeks; Semenax's trial found a modest increase in ejaculate volume over 2 months but no difference in sexual function or orgasm. Both trials were small, and neither has been independently repeated.
An herbal blend (damiana, Asian red ginseng, muira puama, hawthorn, catuaba, saw palmetto, ginkgo and Bioperine) from Leading Edge Health. It's one of the few products in this category with a published placebo-controlled trial of the product itself: 75 men, 12 weeks, better erection scores than placebo. The trial was small and used an older, higher-dose formula.
A 16-ingredient amino acid and herbal blend (including L-arginine, L-lysine, zinc and Swedish flower pollen) from Leading Edge Health, marketed for semen volume. One small, company-funded trial found a modest volume increase versus placebo.
VigRX Plus is our top pick among male sexual-health supplements and Semenax is our top pick among semen-volume supplements. Whichever you choose, buy from the official site so the 67-day guarantee applies.
Neither is better overall because they target different goals. VigRX Plus is our top pick among male sexual-health supplements and Semenax is our top pick among semen-volume supplements.
VigRX Plus is an eight-herb blend aimed at erection quality. Semenax is a 16-ingredient amino acid and herbal blend (including L-arginine, L-lysine, zinc and Swedish flower pollen) aimed at semen volume. Neither sales page lists per-ingredient amounts.
Some men consider both because they target different things, but both contain hawthorn and Semenax adds L-arginine, which can lower blood pressure. Check with a doctor before combining them, especially if you take heart, blood pressure or ED medicines.
From the official VigRX Plus website. Its guarantee requires empty containers to reach the warehouse within 67 days of delivery, excludes shipping and is limited to one order per customer; the terms don't say they cover third-party purchases. Counterfeits with hidden ED drugs have been found, which is another reason to buy direct.
VigRX Plus contains ginkgo and ginseng (blood thinner and diabetes medicine interactions). Semenax contains L-arginine and hawthorn (take care with nitrates, ED drugs and blood pressure medicines) and flower pollen (pollen allergy). Counterfeits of both have been documented, so buy direct. See a doctor about persistent erection problems.
