Built on evidence.
Dosed to be felt.*
Kane® isn't a one-note testosterone pill. It's a full-spectrum formula built around how a man actually performs — strength, recovery, energy, mood, and drive. Every active is open-label, dosed at levels used in real human research, and working toward the same goal: a stronger, sharper, more capable you.*
Strength*
Support for real gains in the gym — power, size, and force.*
Recovery*
Bounce back faster and train more often, with less breakdown.*
Energy & Stamina*
Steady physical drive and endurance that lasts all day.*
Mood & Calm*
Support for a healthy, balanced response to everyday stress.*
Drive & Vitality*
Libido, confidence, and the everyday vitality that defines a man.*
Healthy Testosterone*
Support for your body's own natural testosterone production.*
Nine actives. Nothing hidden.
No proprietary blends. No fairy dusting. Every ingredient is printed on the label with its exact dose — and chosen because it's backed by published human research. Here's the full lineup.
A premium root extract that helps the body handle stress while supporting strength, recovery, and healthy testosterone.*
A standardized seed extract dosed exactly as it was studied — for drive, strength, and male vitality.*
A time-tested botanical used for centuries to support male drive, libido, and everyday vitality.*
A prized Southeast Asian root traditionally used for energy and male vitality, supporting healthy testosterone and drive.*
A rare purple ginger that supports blood flow, stamina, and physical performance — how a workout actually feels.*
A concentrated green-tea catechin that supports metabolism and helps defend against the stress of hard training.*
Acts more like a hormone than a vitamin — a foundation for strength, mood, and healthy testosterone.*
An essential mineral your body uses to make testosterone — and one active men lose through sweat.*
Supports recovery, sleep, and healthy hormone balance — and it's easily depleted by hard training.*
Kane® is dosed at levels used in published research — often at, or above, the amounts shown to work in human trials. What you see on the label is what's in the bottle.*
What the research shows.
The ingredients in Kane® have been studied in real, published human trials. Here's a plain look at what those studies found.
Figures below are from published human trials on the individual ingredients in Kane®, at or near the amounts used in Kane®. Results reflect the ingredient studied, not the finished product, and individual results vary.
Strength & Muscle*
Men lifted significantly heavier after supplementing during a training program.*
Recovery & Leanness*
More body-fat loss and less muscle breakdown across the same program.*
Mood & Calm*
A meaningful drop in cortisol — the hormone your body releases under stress.*
Stamina & Everyday Strength*
Stronger grip, faster movement, and more energy output in as little as 4 weeks.*
Drive & Vitality*
The part of male performance that shapes how a man feels every single day.*
In a 12-week study of men aged 43–70, a standardized fenugreek extract significantly improved sexual function and reduced the everyday symptoms of low vitality. Paired with tribulus — a botanical used to support male drive for centuries — and black ginger's support for healthy blood flow, Kane® rounds out the whole picture of vitality: libido, confidence, and drive.*
The whole is greater than the sum.*
Most testosterone products push on a single dial. Kane® is built differently. Its ingredients work on several fronts at once — and that's what makes the formula more than a list of parts.*
Clear the way
High stress works against a man's hormones. The adaptogens in Kane® help calm the stress response, clearing the path for everything else to work.*
Supply the raw materials
Your body needs the right building blocks to run well. Essential minerals and vitamin D3 form the foundation strength and vitality are built on.*
Feel it day to day
While the deeper support builds slowly, ingredients for energy, blood flow, and drive help you feel stronger and sharper in the here and now.*
A stronger, more capable you — over time.*
Because Kane® works with your body rather than forcing it, consistency is everything. The research points to the biggest changes showing up over weeks and months of daily use — which is exactly why Kane® is built to be taken every day.*
