A letter from the founder

I built this for the people who run toward it, because I needed it first.

I'm KJ. I've spent my career in the fire service, so I'll skip the part where I explain shift work to you.

You know what the job does. The call comes in the middle of the night, your heart rate goes from asleep to wide open in a few seconds, you handle it, and then you're supposed to wind back down like nothing happened. Do that for enough years and the tired stops going away on your days off.

The part nobody talks about at work is what's left when you get home. You gave the shift everything. The people who waited for you get what's left, and some weeks that isn't much. Less patience. Less energy for your kids. Less drive for the gym or for anything that isn't the couch.

Broken sleep is part of the job. Running on empty at home doesn't have to be.

I went looking for help the same way a lot of us do. I bought what the people I work with were taking. I read the labels and found blends with no amounts on them, so I had no way to know what I was swallowing or whether it matched anything in the research. None of it did much, and I got tired of guessing.

So I stopped guessing. I got my labs done, read the studies, and built the thing I couldn't find: a formula with every amount printed on the label and a lab report anyone can read.

I'm not the only one who has asked what this kind of work does to a man's hormones. Researchers have asked it too, and the studies that exist so far are on firefighters. They describe a group. They are not a statement about you, whatever patch you wear. The only way to know where you stand is to get your own labs.

Here is what Foundation is. A daily supplement: two capsules with a meal, no caffeine, no stimulants. Eight ingredients, each dosed at or near the amounts used in human research, chosen to support healthy testosterone and to help with the things this job throws at it: stress, poor sleep, and low energy.

Here is what it isn't. It isn't a drug and it doesn't contain hormones. It doesn't diagnose or treat anything, and it won't fix a schedule that takes your sleep. It's one layer. Every bottle comes with the Foundation Course, 12 modules on labs, sleep, training and stress, and the private GreaterT community, because the capsule is the easy part.

And the risk of trying is on us. 90-day money-back guarantee. If your first bottle isn't for you, we'll refund it. Terms apply.

Your annual physical already checks your heart. Ask for the hormone panel while you're there. Read the label. Then decide.

Questions

Before you decide.

Who is GreaterT Foundation for?

Foundation is for adult men who want to support healthy testosterone, whether they feel “off” right now or already feel decent and want to take care of it. If you want steadier energy, better recovery, stronger drive, or you simply don't want to ignore what's happening as you age, Foundation was built for you.

How long until I see results?

Some men notice changes in sleep, energy, or mood in the first few weeks. Hormonal change takes longer. Most of the ingredients in Foundation were studied over 8 to 12 week periods, which is why we recommend consistent use for the full 90-day cycle. We also encourage a baseline lab test before starting and a retest at 8 to 12 weeks, so your results are measured, not just felt.

Is GreaterT Foundation third-party tested?

Yes. Every batch is tested by an ISO/IEC 17025 accredited lab for heavy metals, microbial contaminants, and label potency on the vitamins and minerals. The Certificate of Analysis for the current lot is posted on this site, so you can read the results yourself before you buy.

Where is Foundation manufactured?

In the United States, in a cGMP facility. Ingredients are globally sourced from trusted suppliers, then tested and produced domestically for purity, potency, and consistency.

Will this make me jittery or keep me up after a shift?

No. There is nothing stimulant in Foundation. The ingredients were chosen to support healthy testosterone and healthy cortisol so your body can wind down and recover overnight, which is the opposite of what a pre-workout or an energy drink does.

Do I need a lab test first?

We recommend it. A baseline before you start and a retest at 8 to 12 weeks is how you know what changed instead of guessing. The Foundation Course covers which panels to ask for and how to read them. If you'd rather start without one, you can, and the guarantee is the same either way.

Something left for the people who waited for you. The risk of trying is on us.
