Tribulus terrestris is a widespread weed in warm regions.

The proposed active component is the steroidal saponin


- Heightens Testosterone Levels

- Increases Sex drive (sexual drive)

- Increases muscle mass and strength

Now let's look at each of these claims in detail with the circulated 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 Testosterone - the research is scarce!

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

Researched 21 men, aged 20-36

Bulgarian Tribulus used - supposedly appeared to be 60% saponin content

The blueprint was NOT standardized for protodioscin

2012 - Sexual Libido study: Tribulus together with algae versus Tadalafil (like Viagra) 5mg daily

Studied 70 guys, average age 67

~400mg Tribulus

Was a combo pill with an algae extract and glucosamine

Total Testosterone level almost tripled

Free Testo-sterone level doubled

2009 instructions Influence of Tribulus on sportsperson homeostasis

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


tutorial I am including it because of an appealing 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 androgen deficiency by 31%

DHEA-sulfate by 29%

When it was given to castrated rats

it increased:

Testosterone by 51%

Dihydrotestosterone by 25%

Why is that fascinating?

If you read a lot of the online toxins science on most bodybuilding and work out sites, they tell you that Tribulus works by increasing your production of androgenic hormone or testosterone by acting like LH or even FSH - hormones that make your testes produce more testosterone.


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


The smaller human analyze said no, but the larger a 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 demonstrated higher testosterone (both total together with free testosterone roughly doubled). I will be 34 years old.
