Quoted message said:Greetings, I have taken the supplement that is supposed to
increase the Testosterone level; this supplement includes:
Methoxyisoflavone 200 mg Quercetin 140 mg Ipriflavone 20
mg Chrysin 20 mg 40 Naringenin 20 mg Tribulus terrestris
500 mg Avena sativa Extract (leaf) 25 mg Urtica dioica
Extract (root) 25 mg
Now, what I am concerned about are flavones. I think they
could actually increase the production of estrogen (i.e.
do something opposite of what this supplement is supposed
to do!) based on this study:

What do you think? Am I reading it wrong or this
supplement is a counterproductive mix of testosterone- and
estrogen-potentiating components?
Thanks in advance.
Two of the ingredients, i.e., Avena and Urtica (AKA Nettle)
may bind with
matabolically active testosterone. Tribulus is supposed to
promote LH release from the pituitary, which would also
raise testosterone levels, but there isn't a lot of solid
proof pertaining to this. As far as I know, there is no
published evidence that the other ingredients in this
formula increase testosterone. As for the flavones, they are
notoriously hard for the body to absorb; must show more
activity in vitro than in
vivo. Chrysin, for example, is an excellent estrogen
inhibitor in isolated cell studies, but isn't absorbed
to any meaningful extent in the human body. I wouldn't
worry too much about flavones having active estrogenic
effects. You may want to consider an herbal supplement
called Longjack or Tonkat Ali. This actually does seem
to increase testosterone levels--if changes in libido
are any indication.
