What's inside Natty

8 actives. Every dose on the label, nothing hidden in a blend.

Natty
01 / 08
  1. 01

    Tongkat Ali

    800mgRoot extract

    Eurycoma longifolia root, the most studied natural testosterone ingredient. It works by freeing up bound testosterone and easing cortisol, so more of what you make is usable. 800mg is the top of the range used in human trials, not a sprinkle.

  2. 02

    Black Maca

    800mgGelatinised root powder

    The black variety of Peruvian maca root, gelatinised so it actually absorbs. Traditionally used for stamina, drive and energy. It works alongside your hormones rather than on them, which is why it stacks cleanly with Tongkat.

  3. 03

    Fadogia Agrestis

    800mgStem extract

    A West African stem extract used to support the body's own testosterone signalling through a different pathway to Tongkat Ali. Running both is the point of the formula: two routes to the same result.

  4. 04

    Turkesterone

    400mgStandardised extract

    An ecdysteroid from Ajuga turkestanica. Supports muscle protein synthesis without touching your hormone axis, so there is nothing to suppress and nothing to recover from afterwards.

  5. 05

    Fenugreek

    400mgSeed extract

    Seed extract standardised for its saponins. Supports healthy testosterone and metabolic function, and rounds out the herbal side of the formula at a dose that matches the research.

  6. 06

    Zinc

    60mgZinc citrate

    The mineral that contributes to the maintenance of normal testosterone levels in the blood. Hard training and sweating pull zinc down, so most men who train are running low without knowing it.

  7. 07

    Vitamin D

    20mcgD3 cholecalciferol

    800 IU of D3. Contributes to normal muscle function, bones and the immune system. Most of the UK is low from October to March, so it is in every serving rather than left to chance.

  8. 08

    DIM

    120mgDiindolylmethane

    Diindolylmethane, the compound your body makes from cruciferous veg. Supports healthy oestrogen metabolism so the testosterone to oestrogen ratio stays where you want it as levels rise.

That is the whole formula. No proprietary blends.

Why Your T Levels Matter
Testosterone drives everything—muscle growth, fat loss, energy, libido, confidence, and mental clarity. After 25, levels drop 1-2% every year. NATTY fights back with clinically-dosed ingredients that actually work.
📈
Testosterone Optimisation

Tongkat Ali + Fadogia Agrestis work through different pathways to maximise your natural T production. Studies show Tongkat can increase testosterone by up to 37%. No shutdown. No PCT needed.

🔥
Libido & Performance

Black Maca is legendary for its effects on sexual desire and performance. Combined with Tongkat Ali's proven libido-boosting effects, expect noticeable improvements in the bedroom.

💪
Muscle & Strength

Turkesterone enhances protein synthesis and muscle growth without affecting hormones directly. Stack it with elevated testosterone for accelerated gains and faster recovery.

⚖️
Estrogen Control

DIM optimises estrogen metabolism, keeping your T:E ratio in the ideal range. More testosterone means nothing if estrogen is out of balance—NATTY handles both.

Tongkat Ali 800mg

The king of natural T-boosters. Increases testosterone, lowers SHBG, reduces cortisol. Clinically proven in multiple studies.

Black Maca 800mg

Peruvian powerhouse for libido, energy, and stamina. Works through unique pathways for fast, noticeable results.

Fadogia Agrestis 800mg

Direct testicular stimulation for increased T production. Synergises perfectly with Tongkat Ali for maximum effect.

Turkesterone 400mg

Ecdysteroid for enhanced protein synthesis and muscle growth. No hormonal suppression—pure anabolic support.

Fenugreek 400mg

Supports free testosterone levels and metabolic health. Added libido and strength benefits.

DIM 120mg

Estrogen metabolism support. Keeps your T:E ratio optimised for maximum testosterone effectiveness.

Zinc 60mg

Essential mineral for testosterone production and immune function. Most men are deficient.

When will I notice a difference?

Most people notice energy and training quality first, within two to three weeks. Give it six weeks of daily use before you judge it.
