Tribulus terrestris is a widespread weed inside warm

Tribulus terrestris is a widespread weed inside warm regions.

The proposed active ingredient is the steroidal saponin

.

- Accelerates TestosteroneLevels

- Increases Sex drive (sexual drive)

- Increases muscles and strength

Now let's study each of these claims in detail with the printed research - this article will focus on the initial claim regarding it's effects upon testosterone. The other claims will be evaluated in future articles.

Tribulus increases Androgenic hormone or testosterone - the research is scarce!

2005 - Tribulus does not influence typically the androgen production in young men

Examined 21 men, aged 20-36

Bulgarian Tribulus used - supposedly was basically 60% saponin content

The strategy was NOT standardized for protodioscin

this is Sexual Libido study: Tribulus plus algae versus Tadalafil (like Viagra) 5mg daily

Studied 70 men, average age 67

~400mg Tribulus

Was a combo pill with an dirt extract and glucosamine

Total Androgenic hormone or testosterone level almost tripled

Free Androgenic hormone or testosterone level doubled



2009 rapid Influence of Tribulus on sportsman homeostasis

Study from Lithuania, I could only get my hands on the abstract not the full paper. States

.

aid I am including it because of a unique takeaway point

2008 - Tribulus terrestris and its hormonal effects about primates, rabbits, and rats

Tribulus terrestris given to primates (by injection) increased

Testosterone by 52%

Dihydrotestosterone by 31%

DHEA-sulfate by 29%

When it was given to castrated mice

it increased:

Testosterone by 51%

Dihydrotestosterone by 25%

Why is that fascinating?

If you read a lot of the online junk science on most bodybuilding and exercise sites, they tell you that Tribulus works by increasing your production of testo-sterone by acting like LH or even FSH - hormones that make your current testes produce more testosterone.

.

Tribulus terrestris must be working to increase testosterone in a different way - possibly by metabolism into steroid precursors like DHEA or Androstenedione.

.

The smaller human study said no, but the larger a person said yes, so did the pet study.

I have used a specific standardized model of Tribulus terrestris myself, and actually had blood tests done that confirmed higher testosterone (both total together with free testosterone roughly doubled). I am 34 years old.
