Good for: Men who want a bigger ejaculate and accept that the only trial is an unpublished, maker-funded report.
Skip it if: You are trying to conceive (see a fertility doctor; it did not improve sperm in its own trial), take blood-pressure drugs (high-dose L-arginine can lower blood pressure), or are allergic to pollen.
Visit Semenax
Semenax is a volume pill from Leading Edge Health: amino acids (L-arginine, L-lysine, L-carnitine), zinc, Swedish flower pollen, pumpkin seed, maca and vitamin E, taken several capsules a day. It promises bigger loads and longer, stronger orgasms and calls itself "Clinically Proven".
The proof is a 2012 report by a contract research firm, sponsored by the seller and never, as far as we could find, published in a journal. It randomized 78 men, analysed 63, and ran two months. Average semen volume rose about half a millilitre on Semenax and fell slightly on placebo. That is the whole effect: sperm counts and erection scores did not beat placebo. A modest, single, unreplicated result is not "clinically proven". The ingredients are mostly ordinary nutrients; our ingredient guide covers L-arginine and zinc.
It is $59 for a month, down to $33 a bottle if you prepay a year. Watch the "Subscribe" tab: it bills $49 every 30 days, with the first rebill after only 25 days, until you phone to cancel. The guarantee needs the two empty containers back within 67 days of delivery, at your cost.
Verdict: harmless for most men but probably not worth $59 a month for half a millilitre. If the real worry is erections or fertility, see a doctor; start with ED treatments that work.
The facts
- Cost
- On the official site (Nov 10, 2026): one bottle (30 days) $59, three $159, six $289, twelve $399, free shipping to the lower 48 states. The "Subscribe" option bills $49 a bottle every 30 days, with the first rebill after only 25 days, until you cancel by phone.[1][2]
- What it claims
- Promises more ejaculate and stronger orgasms and calls itself "Clinically Proven". The blend includes Swedish flower pollen, L-arginine, L-lysine, zinc, L-carnitine, pumpkin seed, maca and vitamin E.[1]
- Evidence
- One trial, posted by the seller as an unpublished 2012 report by contract researcher Vedic Lifesciences, sponsored by Leading Edge Marketing: 78 men randomized, 63 analysed, two months. Semen volume rose about 0.5 mL on average against a 0.2 mL fall on placebo, but sperm measures and erection scores did not beat placebo. We found no peer-reviewed publication and no independent trial.[3]
- Billing & refunds
- 67-day guarantee: return the two empty containers, plus any unopened ones, so they arrive within 67 days of delivery. Shipping isn't refunded, you pay return postage, and refunds are limited to one order per customer. If you chose the subscription, cancel by phone before the next rebill.[1][2]
- FDA & FTC actions
- None found for this product: no FDA hidden-drug notice, recall or FTC case. Its seller, Leading Edge Health, got an FDA warning letter in June 2026 over two other products (Erectin Stimulating Gel and VigRX Delay Wipes). That is not proof of safety: FDA says sexual-enhancement supplements are likely to contain hidden drugs.[4][5][6]
