Flip the bottle
A proprietary blend is a total with the amounts left out.
Pick up almost any testosterone support bottle and turn it over. You'll often find a blend with a trademarked name, one total weight, and a list of ingredients under it. What you won't find is how much of each one you're taking.
The ingredient you bought it for could be most of the capsule or a trace of it. The label doesn't say, so you can't check it against anything.
Where the dose hides
The research was done at a dose. A blend doesn't have to match it.
Human studies on these ingredients used specific amounts: 10 mg of boron, 200 mg of Tongkat Ali, 500 mg of Shilajit. A blend lets a brand print the ingredient's name on the front and put a fraction of the studied amount in the capsule. The industry has a name for that. Fairy dust.
An amount you can't see is an amount you can't check. Not against the research, not against another product, not against what you paid.
What we do instead
Eight ingredients. Eight amounts. One lab report.
Foundation has no proprietary blends. Every ingredient is listed with its amount per two-capsule serving, dosed at or near the levels used in human research. Every batch is tested by an ISO/IEC 17025 accredited lab for heavy metals, microbial contaminants, and label potency on the vitamins and minerals, and the report for the current lot is posted so you can read it yourself.
- Foundation. Two capsules a day with a meal. No caffeine, no stimulants.
- The Foundation Course. 12 modules: which labs to run, how to read them, training, sleep, stress, and the things in your environment that work against your hormones.
- The GreaterT community. Private, included with every bottle.

What buyers say
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

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.
What is a proprietary blend, and why doesn't Foundation use one?
A proprietary blend lists a group of ingredients under one name and one total weight, without the amount of each ingredient. It is legal, and it means you can't tell how much of any single ingredient is in the capsule. Foundation doesn't use one. All eight ingredients are listed with their amounts per two-capsule serving, so you can compare each one to the research and to any other label.
What does the lab report show?
The Certificate of Analysis is the lab's report on the lot currently shipping. It shows what the lab tested: heavy metals, microbial contaminants, and label potency on the vitamins and minerals, with the result for each line. It is posted on this site so you can read it before you buy.
