Chrysin is a plant flavone, a naturally occurring isoflavone extracted from the passionflower family. Research suggests that chrysin has an effect on the bulking of the body by increasing testosterone levels. Unlike some other prohormone supplements like androstenedione, chrysin does not raise testosterone production, but raises levels by blocking its breakdown into estrogens. Chrysin is believed to block the enzyme, aromatase, which makes this conversion.

Using DHEA, androstenedione or anabolic steroids could cause an increased testosterone level, but this may increase estrogen levels and promote breast changes and shrinkage of testis in men. In women facial hair, a deepening of the voice or other masculine traits may occur as well as reduction in estrogen production.

Chrysin appears to be safe. The general consensus is a dosage of 1-3gm of Chrysin daily is effective to maximize the benefits from a workout. Take one half of the dosage in the morning one hour before training and the other half at bedtime. Women generally should not take chrysin.

Chrysin is poorly absorbed when taken orally, but the beneficial effects of this phytonutrient are seen when applied topically.

It is reported that absorption of chrysin, along with other nutrients, is enhanced with the concomitant use of bioperine.


Chrysin can help with the following


Low Testosterone Level

In a study published in Biochemical Pharmacology (1999, Vol.58), the specific mechanisms of chrysin’s absorption impairment were identified. It was found that the addition of a pepper extract (piperine) significantly enhances the bioavailability of chrysin. Studies have found that when chrysin is combined with piperine, reductions in serum estrogen (estradiol) and increases in total and free testosterone result in 30 days.


Highly recommended



The principal male sex hormone that induces and maintains the changes that take place in males at puberty. In men, the testicles continue to produce testosterone throughout life, though there is some decline with age. A naturally occurring androgenic hormone.


Specific protein catalysts produced by the cells that are crucial in chemical reactions and in building up or synthesizing most compounds in the body. Each enzyme performs a specific function without itself being consumed. For example, the digestive enzyme amylase acts on carbohydrates in foods to break them down.


Dehydroepiandrosterone (DHEA) is a steroid produced by the adrenal glands and is the most abundant one found in humans. DHEA may be transformed into testosterone, estrogen or other steroids. It is found in the body as DHEA or in the sulfated form known as DHEA-S. One form is converted into the other as needed.


Anabolic compounds: Allow the conversion of nutritive material into complex living matter in the constructive metabolism.


Any of a large number of hormonal substances with a similar basic chemical structure containing a 17-carbon 14-ring system and including the sterols and various hormones and glycosides.


One of the female sex hormones produced by the ovaries.
