Dr. Cowley's formula combines herbal and botanical extracts into a uniquely powerful male enhancement supplement.  The Xytomax ingredients list is the result of countless hours of research and experimentation.  A brief description of the key ingredients follows.

Niacinamide (vitamin B3)

One of the water-soluble B-complex vitamins, niacinamide has been proven in clinical studies to elevate dopamine levels, a hormone that can increase sexual arousal and function.   

Zinc (zinc oxide)

This essential mineral is required for protein production and is part of more than 200 enzymes in the body.  For instance, zinc is vital to the body’s production of semen.  It can also aid with sexual health and performance.

Epimedium saggitatum (standardized to 10% icariin) 

This ancient Chinese herb is traditionally known as Horny Goat Weed.  According to legend, its aphrodisiac effects were discovered by shepherds whose flocks ate the plant and went into a sexual frenzy.  In addition to its strong aphrodisiac effects, icariin seems to counteract the chemical processes that cause sexual dysfunction.

Maca root

A respected plant from Peru, maca root is famed for its ability to energize the body and improve sexual vitality. South Americans regard maca as a substitute for Viagra-like pharmaceuticals.

Guarana extract (standardized to 20% caffeine) 

Guarana is a creeping shrub that is native to Venezuela and northern Brazil.  It has stimulant as well as aphrodisiac properties.

Korean ginseng root

An ancient aphrodisiac that has been used in folk medicine for over 2,000 years, Korean ginseng root is said to be a sexual enhancer that causes stimulation of the genital area to heightens pleasure.  In addition ginseng is an adaptogen, which helps the body cope with stress.


This amino acid helps form nitric oxide, which is crucial to the vasodilatation of the penile area, producing swelling and hardness.  Elevated levels of l-arginine help to create permanent growth in the penis by stretching the erectile chambers over time.

Usage of the botanical longjack can enhance the libido, maximize testosterone production and create massive ejaculatory volumes.  

Avena sativa (concentrated 10:1 )

Ginkgo Biloba extract (24% flavoneglycosides & 6% terpenelactones) 

The ginkgo is said to be among the oldest living tree species in the world.  The trees extract has been used to help men with sexual dysfunction problems by increasing drive and stamina.

Saw palmetto (berry) 

Saw palmetto primarily acts to help bring the body’s hormones into balance. It can also act as a sexual stimulant and aphrodisiac, facilitating arousal.

Xanthoparmelia Scabrosa extract 

The Chinese have used the seeds of Xanthoparmelia Scabrosa to extend the duration of an erection by increasing vasodilatation for centuries.  The seeds can also cause muscle relaxation, inducing a rise in blood flow to the penis so that it stays erect longer.

Cnidium Monnieri extract 

This extract has been found to help relax the corpus cavernosa of the penis, which aids blood circulation and provides longer, stronger erections that boost sexual energy.

GABA (Gamma amino butyric acid) 

Gaba Increases dopamine levels, igniting a euphoric feeling and increasing sensations during orgasm GABA is good for depressed sex drive because of its ability as a relaxant.
