Your T Is Falling. The System Isn't Helping.
Testosterone levels in men have dropped more than 20% in the last two decades and it has nothing to do with aging. It's your environment, your diet, and a system that was never designed to help you fix it.
- Low energy and constant fatigue
- Reduced drive and motivation
- Difficulty building or maintaining muscle
- Brain fog and poor focus
- Poor sleep quality
A lot of men are told their levels are "normal", but normal has never been lower.
What It Supports
What Foundation is built to support.
Eight ingredients, each dosed to the research and printed on the label, chosen to support healthy testosterone and to help with the things that work against it: stress, poor sleep, and low energy.
- ENERGY
Steady energy through the day, not a spike and a crash. Foundation contains no caffeine and no stimulants.
- DRIVE
Support for healthy testosterone, the hormone behind motivation, libido, and the pull toward the things you used to want.
- RECOVERY
Support for training recovery and the muscle you work for, with the nutrients your body uses to maintain its own testosterone.
- SLEEP AND STRESS
Support for healthy cortisol levels, so your body can wind down, sleep, and actually recover overnight.
Our Story
Why it exists.
Foundation wasn't built in a boardroom. It came from years of research and direct work with men whose doctors told them everything was fine. We stopped asking how to boost testosterone and started asking what was getting in its way. Foundation is not a test booster. It's the supplement layer of a complete system: testing, training, stress control, and removing the things in your life that work against your hormones.

What To Expect
Your 90-Day Cycle.
Some men notice changes in sleep and energy early. Real hormonal change takes the full cycle. Here is the protocol, start to finish.
Weeks 1 to 2
Start
Two capsules a day with a meal. Start the Foundation Course and get a baseline lab test if you haven't already.
Weeks 3 to 7
Stay consistent
Keep the dose daily. Work the course: sleep, training, stress, and the things in your environment that work against your hormones.
Weeks 8 to 12
Retest
The ingredients in Foundation were studied over 8 to 12 weeks. This is the window to retest your labs and compare them to baseline.
After week 12
Assess and cycle
Take a one-week break, look at your labs and how you feel, and decide what's next.

The Receipts
Men don't hype. They re‑order.
★★★★★
This is the best men's health supplement that I have found. I compared the ingredient lists with other supplements, and GreaterT hands down has higher dosages of the ingredients that we need, especially as a middle-aged man. This is the cream of the crop

Extremely happy with my subscription. Two capsules let me cut down the number of individual supplements I was taking, and they work great.

Frequently Asked Questions
Everything you need to know about Foundation and the GreaterT protocol.
Most testosterone supplements are just a pill and a label. Foundation is part of a complete system. Every purchase includes free access to the 12-module Foundation Course and the GreaterT community, where we cover training, nutrition, sleep, lab testing, and removing endocrine disruptors from your environment. The supplement works best as part of that protocol, and that's what separates results that last from results that don't.
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.
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.
You can take Foundation on its own. But it was designed to work alongside the GreaterT protocol, which addresses the lifestyle factors that suppress testosterone in the first place: stress, poor sleep, nutritional gaps, and environmental disruptors. Members who combine Foundation with the course and community consistently see stronger results.
Yes. Every ingredient was selected based on human research involving testosterone, stress hormones, nutrient status, or hormonal signaling. We intentionally avoided formulas that pack in dozens of ingredients at ineffective doses. Foundation uses clinically relevant amounts of well-studied compounds: Tongkat Ali, Shilajit, Ashwagandha, Zinc, Vitamin D3, and Boron. Supporting research is linked in the research section of this page and throughout the Foundation Course.
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.
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.
Many natural compounds that support hormones, particularly adaptogenic herbs, work best in cycles. After approximately 12 weeks of use, we recommend a one-week break. This helps maintain sensitivity to the ingredients and gives your body a short reset. Most brands will tell you to take their product indefinitely. We'd rather you get lasting results than a lasting subscription.
In most cases, yes. Foundation is designed as a core hormone support supplement and stacks well with general wellness products like magnesium, omega-3s, or protein. If you're currently on prescription medications or hormone therapies, check with your healthcare provider before adding any new supplement.
No. Foundation is not intended to diagnose, treat, cure, or prevent any disease and is not a substitute for medical care. That said, many men choose to optimize naturally before exploring medical interventions. GreaterT exists for exactly that, giving you the best possible shot at strong, healthy testosterone through lifestyle and the right supplementation.
