You already know the basics. Sodium. Potassium. Magnesium. Every electrolyte on the market has them.

But there are two minerals your hormones depend on that aren't in any of them.

Zinc is the foundational mineral for testosterone synthesis, over 300 enzymatic reactions in your body run on it. Most men are chronically low and don't know it.

Boron reduces SHBG, the protein that binds to your testosterone and keeps it locked up and unavailable. When SHBG is high, your free testosterone stays trapped regardless of what your bloodwork says.

Standard electrolytes hydrate you. Core does that, and gives your hormones what they've been running without.

Is this just overpriced salt water like the other brands? Core contains sodium, potassium, magnesium, zinc, and boron in clinical ratios. LMNT charges $1.50 per serving for 3 electrolytes with zero testosterone support. Core delivers 5 minerals including zinc and boron at $1.33 per serving. Do the math on the side-by-side.

Unlike LMNT, Liquid IV, and every other electrolyte on the market, we didn't build this for everyone.

Sodium, potassium, magnesium. They keep you hydrated. That's it. That's where every electrolyte on the market stops.

But your body doesn't stop there. Your energy, your drive, your recovery, how you feel at 3pm, how present you are at night. That's your hormonal environment. And that system runs on two completely different minerals.

Zinc and boron. The two minerals your testosterone depends on most. The two minerals chronically low in most men over 30. The two minerals you won't find on a single major electrolyte label.

How is this different from LMNT, Liquid IV, Mars Men, or any other electrolyte or testosterone brand? LMNT built the category. Liquid IV made it mainstream. Mars Men stepped masculine branding on a cheap formula. Core built what all of them should have been. LMNT carries an active class action lawsuit alleging 382 to 459mg of undisclosed monk fruit sugar in every serving. It also has zero testosterone support. Liquid IV loads sugar and targets the mass market, not optimized men. Mars Men sells the aesthetic of optimization while cutting corners on the actual ingredients that matter. None of them include the full mineral stack that moves the hormonal needle. Core does.

Why not just make my own electrolyte mix for pennies? You can. Most men who try it quit within 2 weeks. The taste is inconsistent, sourcing 4 to 5 separate ingredients is a recurring hassle, and you cannot DIY the zinc and boron in clinical ratios and support testosterone. Core costs less than homemade once you factor in all 5 ingredients.

They chose everyone. We chose you.

Every ingredient that matters. Right here. Nothing hidden. No bullsh*t.

• 1,000mg Sodium — replaces what you actually lose in a serious sweat session
• 250mg Potassium — fluid balance and muscle function
• 80mg Magnesium — recovery, sleep quality, and muscle repair
• 5mg Zinc — foundational mineral for testosterone synthesis
• 3mg Boron — reduces SHBG, freeing the testosterone already in your system
• 100mg Beetroot Powder — natural nitric oxide support for blood flow and endurance

Zero sugar. Zero calories. Zero carbs. Zero artificial colors. Third party tested. GMP certified. If you read every label, this one's for you.

1,000mg of sodium sounds dangerous. My doctor told me to cut salt. The study behind that advice fed the human equivalent of 550g of sodium per day. 161,945 people in the PURE study showed mortality risk actually increases where intake drops below 3,000mg daily. 33% of Boston Marathon runners developed dangerously low sodium from over-hydrating. Low-sodium guidelines are the most contested nutrition position in preventive medicine.

One stick. 450–500ml of cold water. Shake until dissolved. That's the entire protocol.

Most men take it first thing in the morning, before coffee, before training, before the day takes anything of them. Some take it pre workout. Some take it at 2pm before the wall shows up. There's no wrong answer. There's just the question of whether you start.

I don't train that hard. Is this even for me? You do not need to be an elite athlete to be depleted. The desk professional sitting under fluorescent lights for 8 hours loses electrolytes through stress cortisol spikes as much as the construction worker sweating through a full shift is hemorrhaging sodium and magnesium before he even touches a weight. The average gym goer training 3 to 4 times a week is replacing calories but never replacing minerals. Every one of these men has the same wall: afternoon crash, low drive, slow recovery, foggy focus. The cause is the same. The fix is the same.

How long until I notice a difference? Most men report the afternoon energy crash disappearing within the first 3 to 5 days of consistent use. The hormonal layer from zinc and boron builds over 2 to 4 weeks. If you notice nothing in 30 days, full refund, no questions.

30 days. If you don't notice a difference in your energy, your recovery, or how you feel by the end of your first box, one email and we refund every cent. No forms. No fine print. No questions.

We don't offer this because we're generous.

We offer it because we know what zinc and boron do for a man who's been running without them.

The only risk is not finding out.
