Is Semenax worth it?
Worth a 67-day experiment if this category interests you: every dose printed on the label, a real placebo-controlled trial you can read, and 67 days from delivery to send the empty containers back.
Read from the maker's store on Aug 28, 2026, in USD; shipping was free for continental US orders on our check.
Every pack on the store page is priced as a one-time purchase; on the 3-, 6- and 12-bottle quantities the maker also offers a "4 easy payments" instalment plan
Replicating the trial (8 caps/day for 2 months) takes about four bottles: $218 as a 3-pack plus a single bottle
The Supplement Facts panel prints the amount of every ingredient, from zinc aspartate 30 mg (6 mg elemental zinc) and maca (400 mg) to L-Arginine HCL (250 mg), L-Lysine (250 mg), pine bark (300 mg) and a set of herbal extracts down to 30 mg.
This is a dietary supplement, not medicine, and nothing here is medical advice; fertility concerns, medication interactions or persistent changes deserve a urologist.

The protocol: 63 men, two months, placebo-controlled
The volume claim rests on a real document: a two-month trial run by the contract lab Vedic Lifesciences.
Here is the file, with the study's own conclusions quoted from it.
"A higher number of patients in the Semenax® arm showed a 20% or more Increase in ejaculate volume as compared with the placebo."
The study's conclusion as quoted on Semenax's own trial page: Effect of Semenax Capsules on Semen Characteristics, Vedic Lifesciences, read Aug 28, 2026"Semenax showed statistical significance over the placebo with respect to the investigator's global assessment and the patient's global efficacy assessment."
Same source; global assessments are overall impressions recorded by the investigator and the participantDouble-blind, against a placebo, for two full months. Neither the men nor the investigators knew who was on Semenax, and every volume reading was set against the placebo arm.
Two readings came out ahead of the placebo. More men in the Semenax arm crossed the 20% volume-rise mark, and both the investigator's global assessment and the patient's own efficacy assessment reached statistical significance.
The trial's serving, and the bottle's. The study gave 4 capsules twice a day; the bottle is sold as a 30-day supply at the label serving of 4 a day. Running the trial's own schedule for two months takes roughly four bottles.
The maker's study page also displays the product's registration with Health Canada as a natural health product.
The label actually shows its numbers
Why that matters: Innerbody's independent review of sibling product Volume Pills, which it scores 2.00 out of 10, singles out this exact difference: Semenax lists all ingredient amounts explicitly, while Volume Pills obscures most doses within a proprietary blend.
Even the category's tougher reviewers give Semenax the transparency point.
Every amount on that panel is there to be checked before you swallow a single capsule, and to be held against anything else on the shelf.
What the independent record says
The independent customer record is genuinely good for this category, with effectiveness the main theme and support handling problems quickly.
"After just 2 weeks on semenax im shooting the biggest loads of my life!"Arnie Wolffe · Trustpilot · Jul 2026
Innerbody reviews this whole category and is hard to please inside it. On the one point a buyer can verify before taking anything, it puts Semenax on top: Semenax lists every ingredient amount explicitly, while the sibling product Volume Pills keeps most of its doses inside a proprietary blend.
Innerbody scores that sibling product 2.00 out of 10.

The 67-day guarantee from delivery is what makes your own test the cheap one to run.
The label's serving is 4 capsules a day, and one bottle holds 120.
Patience, sleep and honesty with your doctor do more than any single capsule.
The packs, priced as charged
Ordering from outside the lower 48? The store as each country sees it is written up in our Semenax review for the UK, for Canada and for Australia.
Per-bottle figures are plain arithmetic.
Four numbers before you decide
- One bottle, $59, run at the label dose for a month: that is the cheapest honest test
- The guarantee window (67 days) outlasts the label-dose bottle (30 days): the return path stays open through a real test
What this means for you: pick the one-bottle pack for the cheapest honest test, run it at the label dose, and the 67 days from delivery outlast that bottle by more than a month.

What happens after you click
You land on Semenax's own store

What the pricing page shows
The bottle grid runs from $59 for one up to $399 for twelve, 120 capsules per bottle, with shipping free for continental US orders on our check; each order form we rendered showed a single total for its quantity. The maker's site today also lists a "4 easy payments" option on the 3-, 6- and 12-bottle quantities, an instalment plan per the maker.
The guarantee clock
Whatever your final total, the 67 days count from the day your order is delivered, per the maker's guarantee page read Sep 2, 2026: return within that window for a refund of the product price excluding shipping and handling, and keep the containers, since the home page describes the return as the two empty containers.

Every objection, answered
Does Semenax actually work?
It is the one product in this category with a two-month, double-blind, placebo-controlled trial you can read. In that trial of 63 men, more men on Semenax than on placebo showed a 20% or larger rise in ejaculate volume, and both the investigator's global assessment and the patient's own efficacy assessment reached statistical significance over placebo. Your own test is the one that settles it for you, and the 67-day window from delivery is sized to cover it.
What dose did the study use, and what does the bottle give you?
The study dosed 4 capsules twice a day, which is 8 capsules daily. The label's serving is 4 capsules per day, and one 120-capsule bottle is sold as a 30-day supply at that label serving. At the trial's own schedule a bottle lasts about 15 days, so running it for two months takes roughly four bottles.
Is Semenax safe? What is actually in it?
The full dose of every ingredient is printed on the label, which is genuinely uncommon in this category: zinc aspartate 30 mg (6 mg elemental zinc), L-Arginine HCL (250 mg), L-Lysine (250 mg), L-Carnitine (500 mg), maca (400 mg), pine bark (300 mg), Butea Superba (500 mg), Swedish flower pollen (50 mg) and further herbal extracts at 30 to 200 mg each. The maker states it is made in cGMP-certified facilities in the USA. Standard sense still applies: it is a dietary supplement, not a treatment, and anyone on medication or managing a condition should ask a doctor first.
How does the 67-day guarantee actually work?
It is an empty-container guarantee: try the product and, if unsatisfied, return the empty containers within 67 days of delivery for a refund of the purchase price, excluding shipping. That window covers a real two-month personal test at the label dose. Keep the containers; the mechanics require sending them back.
Semenax vs Volume Pills: which one?
They come from the same parent company, Leading Edge Health, at similar prices ($59 to $60 for one month, about $33 per bottle in 12-packs). Semenax is the one that prints its numbers: Innerbody's independent review notes that Semenax lists all ingredient amounts explicitly while Volume Pills keeps most doses inside a proprietary blend, and it rates Volume Pills 2.00 out of 10. Between the two, take the one with the readable label.
Where should I buy it?
From the maker's own store. Semenax's own site says to trust only purchases from its store or Leadingedgehealth.com, and its packaging carries an authenticity check you can run on their site. Shipping was free for continental US orders when we checked, and the 67-day guarantee applies to store purchases.
Why this one scores 9.2
This page is built from the maker's own store and study pages (read Aug 28, 2026), the summaries of its trial, Trustpilot's live record and Innerbody's category reviews.
Our 9.2/10 puts Semenax at the top of this category's paperwork: the label, the trial and the guarantee all print their numbers.
The three reasons
Our own rule for anything at 9.0 or above: three reasons, each one checkable at the source. Here they are.
- A label that prints every amount. The Supplement Facts panel gives the quantity of each ingredient. The closest competitor in this category does not: most of its doses sit inside a proprietary blend.
- A 67-day empty-container guarantee. Seven days past this category's usual 60, and wide enough to cover a real personal test rather than an unopened box.
- An independent reputation record with volume. 4.4 out of 5 on Trustpilot from 1,183 reviews, seen August 28, 2026, beside prices of $59 for one bottle and $399 for twelve at the maker's own store.
- The guarantee is concrete: return the empty containers within 67 days of delivery and the product price comes back, shipping and handling excluded.
- The maker's site asks you to buy only from its own store and offers an on-site authenticity check for the packaging; buying from the source is what keeps the guarantee attached to your order.
