Ecdysteroids And Their Effects On Testosterone

Ecdysteroids are found in some male testosterone boosting supplements, but what are they and just how affective can they be?

Rhd0e.qxdEcdysteroids are class of hormones that are actually the androgens of the insect world.. also found in many plants ( about 6% of all plants in existence) they are primarily involved in the reproduction cycle and little else..

Common sources of Ecdysteroids include

  • Asparagus
  • Spinach
  • Quinoa
  • Yams
  • White Button Mushrooms
  • Ajuga Turkestanica
  • Silene
  • Vitex Scabra

Ecdystroids are found in the formulas of some supplements under the names: Suma Root or Extract, Brazilian Ginseng, Beta-ecdysterone, Turketsterone and Ecdysterone.

They get their name as they have a steroid backbone and by their association with the moulting process ( called ecdysis).

They are usually present in plants to help protect the plants from pests and unwanted insectssuma-plant-300x251

Also found in insects, they are hormonal compounds used in the sexual reproduction of insects.

They have a similar makeup to testosterone and is considered the most ‘testosterone like compound’ in insects.

Safe Doses

It is considered that an effective dose is in the region of 200mg per day…

When tested on Rats they have been given 5mg/kg of body weight and it does appear to show anabolic properties.

Clinical Testing looking at Testosterone Boosting in Humans

There have been 6 clinical studies that have looked into the benefits of supplementation with Ecdysteroids..

These range from 2006 to present day.

Only one trial has been carried out on Humans, the rest being performed on both Rats and Mice under strict laboratory conditions.

The Human study was carried out in 2006 at the Human Performance Lab, University of Mary Hardin Baylor, Belton, Texas..

it followed 45 resistance trained males aged between 18 and 29.. over six months they were given 200mg Suma Root ( 60mg Ecdysterone) daily

When the results were evaluated it was apparent that no significant change in testosterone production had taken place in any of the test subjects.

The Studies Conclusion Reads As Follows:

Ecdysterone, and sulfopolysaccharide (CSP3) did not significantly affect anabolic or catabolic responses to resistance training, body composition, or training adaptations.

“Since most of the previous studies reporting positive effects of ecdysterones have been reported in obscure journals with limited details available to evaluate the experimental design and quality of the research, it is difficult to compare results.

Nevertheless, present findings do not support the purported ergogenic benefit of ecdysterone supplementation in resistance-trained males.”


Supplementing with ecdysterone (Suma) has not shown any proven ability to increase testosterone in any male and it must be now assumed that its testosterone boosting effects are negative..
