What it is. SEMEX is the daily men's formula for semen volume and taste: zinc at a full dose, the lecithin and maca that volume formulas are built on, and botanicals for drive. Three capsules a day.

How it works. Zinc and sunflower lecithin support healthy semen production, while maca and horny goat weed support volume and libido. Tongkat ali, muira puama and panax ginseng support drive and stamina, and saw palmetto supports normal prostate function. Copper is included to stay in balance with the zinc.

What's in it. Zinc 50 mg, copper 4 mg, panax ginseng, L-arginine, saw palmetto, tongkat ali, muira puama, longjack and polypodium, plus a 1,700 mg complex of horny goat weed, maca and sunflower lecithin. Vegetarian capsule. 90 capsules, a 30-day supply.

"Others" reflects common practice among mass-market supplement brands. Always compare labels.

What to expect, and when.

SEMEX is a daily formula. Zinc and lecithin levels build within days; the botanicals compound over weeks. Individual results vary, which is why every bottle is covered by our money-back guarantee.

WEEK 1–2

The build-up

Zinc and lecithin levels rise quickly, so the first change most men report is in volume.

WEEK 3–4

Fuller finish

With daily use, maca and horny goat weed support drive while zinc continues to support production.

MONTH 2–3

Peak and hold

Tongkat ali and ginseng support sustained drive and stamina. Keep taking it daily to hold the results.

I wanted proof, not promises. So I built Newt.

Newt started with three questions I asked every brand I was buying from: what’s the exact dose, who tested it, and can I see the report? Not one of them answered all three. So I built the brand that would.

Here are Newt’s answers, for every product we make. The dose isn’t my opinion — it’s the one used in the published clinical studies. The testing is done by an independent, ISO 17025-accredited lab, and every product is made in an FDA-registered, cGMP facility.

My job is the part most of this industry skips: making sure all three happen every single time, and showing you the proof. When someone takes something you made, “close enough” isn’t a standard.

Every product we make is something I’d take myself and give to my family. Trust should be earned with evidence, not promises.

Have a question? Get in touch. I personally read and respond to every message.

Questions before you order.

How much will volume change?

It varies, and the biggest factors are hydration, frequency and your starting point. Most men notice a difference within the first 2 to 4 weeks of daily use.

Does it change taste?

Taste follows diet more than anything else: water, fruit, less alcohol and no smoking matter most. SEMEX supports the raw materials of production and is formulated with that goal in mind.

Can I take SEMEX with ALPHA BULL or MAX ERECT?

Not on the same day. SEMEX already provides 50 mg of zinc, and each of the other two adds 30 mg, which puts you well past the 40 mg daily upper limit. Choose one or alternate days.

Why is there copper in it?

Zinc at this level depletes copper over time. SEMEX includes 4 mg of copper to keep the two in balance.

How long should I take it?

As long as you want the results. It's a daily formula, and volume returns to your baseline a few weeks after you stop.

What happens if I don’t see results?

Every order is covered by our money-back guarantee. Contact support and we'll take care of it.
