Lo vengo diciendo de hace tiempo ya en el foro.. aca dejo algo para erradicar de una vez el tribulus como un buen suplemento para aumentar los niveles de testosterona naturales
Actualmente hay 0 estudios que muestren que el tribulus aumenta la performance de los atletas, y tampoco que muestren un incremento de testosterona
Es un afrodisiaco, nada mas
Aca hay un estudio el cual confirma que no tiene influencia sobre la testosterona (la supuesta funcion principal de este elemento)
Lo marcado en negrita quiere decir en pocas palabras:
Se encontro que el tribulus terrestris no tube accion directa o indirecta sobre un aumento de testosterona
Saludos

OBJECTIVE: The aim of the current study is to investigate the influence of Tribulus terrestris extract on androgen metabolism in young males. DESIGN AND METHODS: Twenty-one healthy young 20-36 years old men with body weight ranging from 60 to 125 kg were randomly separated into three groups-two experimental (each n=7) and a control (placebo) one (n=7). The experimental groups were named TT1 and TT2 and the subjects were assigned to consume 20 and 10 mg/kg body weight per day of Tribulus terrestris extract, respectively, separated into three daily intakes for 4 weeks. Testosterone, androstenedione and luteinizing hormone levels in the serum were measured 24 h before supplementation (clear probe), and at 24, 72, 240, 408 and 576 h from the beginning of the supplementation. RESULTS: There was no significant difference between Tribulus terrestris supplemented groups and controls in the serum testosterone (TT1 (mean+/-S.D.: 15.75+/-1.75 nmol/l); TT2 (mean+/-S.D.: 16.32+/-1.57 nmol/l); controls (mean+/-S.D.: 17.74+/-1.09 nmol/l) (p>0.05)), androstenedione (TT1 (mean+/-S.D.: 1.927+/-0.126 ng/ml); TT2 (mean+/-S.D.: 2.026+/-0.256 ng/ml); controls (mean+/-S.D.: 1.952+/-0.236 ng/ml) (p>0.05)) or luteinizing hormone (TT1 (mean+/-S.D.: 4.662+/-0.274U/l); TT2 (mean+/-S.D.: 4.103+/-0.869U/l); controls (mean+/-S.D.: 4.170+/-0.406U/l) (p>0.05)) levels. All results were within the normal range. The findings in the current study anticipate that Tribulus terrestris steroid saponins possess neither direct nor indirect androgen-increasing properties. The study will be extended in the clarifying the probable mode of action of Tribulus terrestris steroid saponins.
