What is Tribulus Terrestris?
Tribulus terrestris is a natural herb, commonly known as the puncture vine, that has been used for centuries in Europe as a treatment for impotence and as a stimulant to help enhance sexual drive and performance. On the athletic front, this potent herb has been studied and observed to enhance LH (luteinizing hormone) production and boost testosterone levels. This powerful extract, like DHEA and Androstenedione, can help elevate testosterone levels safely and its effects have been coveted by Bulgarian athletes for decades.
Why should I use Tribulus Terrestris?
Like DHEA and Androstenedione, Tribulus terrestris can naturally support testosterone production. Testosterone is vital because it plays many key roles in our bodies including building muscle size and strength. Athletes are using Tribulus terrestris to help ensure that their levels of this natural hormone are at normal levels at all times. This can thus ensure that testosterone levels are maintained through a natural platform without the use of dangerous drugs like steroids.
What research has been done on Tribulus Terrestris?
When scientists first started researching Tribulus terrestris, it was for the sole purpose of discovering a safe, natural treatment for sexual deficiencies. This research led to the discovery that Tribulus terrestris significantly elevated LH and testosterone levels. One follow-up study, conducted on healthy men ages 28-45, showed that 3 doses of 250mg taken evenly throughout the day for just five days elevated testosterone levels by 30% or more! Additional studies confirmed the previous study and also showed that, in addition to a rise in testosterone levels, subjects saw an increase in libido, frequency and strength of erections and recovery from sexual activity. Other changes that where noted included: a reduction of cholesterol, improved mood and increased self-confidence.
What doses of Tribulus Terrestris should be taken?
While there is no definitive guide on how much Tribulus terrestris should be taken, there are different guidelines suggested by experts in the medical field. Most suggest 250-750mg per day taken evenly throughout the day.
What side effects are caused by Tribulus Terrestris?
Just as with any supplement, caution should be exercised when considering taking Tribulus terrestris. In the research studies done, no adverse affects where noted from the use of Tribulus terrestris. In addition, further research demonstrated no adverse effects on the central nervous or cardiovascular systems. At this time no toxicity or negative effects presently exist when Tribulus terrestris is used as a nutritional supplement.
Should I cycle Tribulus Terrestris?
There is no evidence that shows conclusively what the optimal usage and duration of Tribulus terrestris should be. Many of the research studies done used 750mg of Tribulus terrestris for short periods of time. Unlike DHEA and Androstenedione, Tribulus terrestris is not manufactured by the body, however, prolonged usage could down-regulate it's effects and make it less potent and long term usage and its effects have not yet been studied, therefore cycling Tribulus terrestris might be advantageous.
There are different "schemes" of cycling that have been reported to work. These include a 3 week "on cycle" followed by a 1-3 week "off cycle", or a descending dosage pattern such as 4-6 weeks "on" followed by 3-6 weeks "off". As is the case with all supplementation, better judgment is the key to success. Knowing your body and its limits is as crucial to proper supplementation as it is to proper training.
