Ecdysteroids as non-conventional anabolic agent: performance enhancement by ecdysterone supplementation in humans
Recent studies suggest that the anabolic effect of ecdysterone, a naturally occurring steroid hormone claimed to enhance physical performance, is mediated by estrogen receptor (ER) binding. In comparison with the prohibited anabolic agents (e.g., metandienone and others), ecdysterone revealed to be even more effective in a recent study performed in rats.
However, scientific studies in humans are very rarely accessible. Thus, our project aimed at investigating the effects of ecdysterone-containing products on human sport exercise.
A 10-week intervention study of strength training of young men (n = 46) was carried out. Different doses of ecdysterone-containing supplements have been administered during the study to evaluate the performance-enhancing effect. Analysis of blood and urine samples for ecdysterone and potential biomarkers of performance enhancement has been conducted. To ensure the specificity of the effects measured, a comprehensive screening for prohibited performance-enhancing substances was also carried out. Furthermore, the administered supplement has been tested for the absence of anabolic steroid contaminations prior to administration.
Significantly higher increases in muscle mass were observed in those participants that were dosed with ecdysterone. The same hypertrophic effects were also detected in vitro in C2C12 myotubes.
Even more relevant with respect to sports performance, significantly more pronounced increases in one-repetition bench press performance were observed.
No increase in biomarkers for liver or kidney toxicity was noticed.
These data underline the effectivity of an ecdysterone supplementation with respect to sports performance.
Our results strongly suggest the inclusion of ecdysterone in the list of prohibited substances and methods in sports in class S1.2 “other anabolic agents”.

Protein biosynthesis was stimulated in liver tissue in vivo and in vitro after administration into mice of either phytoecdizone of turkesterone (0.5 mg/100 g) or of anabolic steroid compound nerobole (1 mg/100 g). Stimulation of protein biosynthesis was due to an increase in functional activity of polyribosomes and to elevation in the synthesis of protein molecules. Actinomycin D, which inhibited the stimulation of protein biosynthesis in liver tissue of mice treated with nerobole, did not affect the phenomenon in mice treated with turkesterone.
Aqueous extract of Bulbine natalensis Baker (Asphodelaceae) stem at 25, 50 and 100 mg/kg body weight was investigated for anabolic and androgenic effects in male Wistar rats. Sixty male rats were grouped into four (A-D) consisting of 15 each. Group A (control) was orally treated with 0.5 mL of distilled water for 14 days while groups B, C and D were treated like the control except they received 0.5 mL containing 25, 50, and 100 mg/kg body weight of the extract respectively. All the doses of the extract increased (P <0.05) the testicular-body weight ratio as well as alkaline phosphatase activity, glycogen, sialic acid, protein, and cholesterol content of the testes except the single administration of 100 mg/kg body weight which compared well (P>0.05) with the controls for glycogen and cholesterol.
The testicular and serum testosterone concentration were increased except in the 100 mg/kg body weight where the effect on the tissue and serum hormone did not manifest until after the first and seven daily doses respectively.
Testicular acid phosphatase activity, serum follicle stimulating and luteinizing hormone concentrations also increased at all the doses except in the 100 mg/kg body weight where the effect on the enzyme and the hormone did not manifest until after seven days.
The increases were most pronounced in the 50 mg/kg body weight extract treated animals.
The results indicate anabolic and androgenic activities of Bulbine natalensis stem in male rat testes with the 50 mg/kg body weight of the extract exhibiting the highest anabolizing and androgenic acti vities. These activities further support the folkloric use of the plant most especially at 50 mg/kg body weight in the management of male sexual dysfunction in South Africa.
