12 ingredients. Nothing hidden.
Most T-boosters lean on proprietary blends and underdosed formulas. High Level Man lists every ingredient and every dose right on the label — 12 clinically studied ingredients, dosed to the research.
Tribulus
Std. 45% saponins. Drive, performance, and male vitality.*
Horny Goat Weed
Std. 10% icariins — the classic blood-flow and libido botanical.*
Fenugreek
Std. 50% saponins. Studied for supporting healthy testosterone.*
Maca
Peruvian root for energy, stamina, and healthy libido.*
Ashwagandha
Std. 2.5% withanolides. Cortisol is testosterone’s worst enemy.*
DIM
Supports healthy estrogen metabolism — the balance most formulas skip.*
Tongkat Ali
100:1 extract — one dose carries the equivalent of 5,000 mg of raw root.*
Zinc
Amino acid chelate. Contributes to the maintenance of normal testosterone levels.*
Niacin
250% DV of full-strength nicotinic acid — the classic form.*
Vitamin D3
The foundational nutrient most men are low in — hormone health depends on it.*
Boron
From 100 mg boron citrate. Studied for supporting free testosterone.*
BioPerine®
Patented black pepper extract that boosts absorption of everything above it.*
Straight from the Supplement Facts panel. 3 capsules, once a day.
Your testosterone peaked years ago.
Men’s testosterone levels have been falling for decades — and they drop with every year after your twenties. Stress, poor sleep, and processed food speed it up. High Level Man was built to support your body’s natural production against that curve — every day, for the long haul.*
*Illustrative of the goal of daily natural testosterone support — not a measurement of guaranteed results. Testosterone declines with age vary by individual. High Level Man supports your body’s own healthy testosterone production; individual results vary.
Reclaim your edge.
Energy & Stamina
All-day output, in life and in the gym*
Drive & Libido
Support healthy male vitality*

Sharp is supposed to be your baseline*

Recovery
Bounce back like you used to*
Day 7. Day 30. Day 90.

- BioPerine is driving absorption of all of it*
- Tongkat, fenugreek, and boron compound with daily use*
- Steadier energy, drive, and training output show up here for many men*
- Workouts start paying you back again*
- The durations the research actually studied — all 12 working as one*
- This is your new baseline, not a spike*

Everything you’re wondering.
Does High Level Man really boost testosterone?
High Level Man combines 12 ingredients studied for supporting your body’s own healthy testosterone production — including tongkat ali, fenugreek, tribulus, zinc, boron, and vitamin D3, at the doses printed on the label.* It contains no hormones; it works by supporting the systems your body already uses. Give it the 8–12 weeks the research studied.
How is this different from the other T-boosters at GNC?
Twelve clinically studied ingredients where most formulas stop short, DIM and BioPerine® most skip entirely, a 100:1 tongkat ali extract, just three capsules a day — and a formula built by a world-renowned interventional cardiologist, with a published third-party COA for every lot instead of a one-time test.

How do I take it?
Three capsules once daily, ideally with a meal. One jar is a full 30-day supply. The ingredients were studied over weeks of consistent daily use — consistency is the whole game.
Is this a hormone or TRT?
No. Zero hormones. High Level Man is a dietary supplement built to support your body’s own production — the opposite approach to replacement. If you think you may have clinically low testosterone, talk with your doctor.
