• Tribestan improves muscle growth & body strength
• Tribestan reported to enhance libido sexualis & erectile function
• Tribestan reported to increase the number and motility of spermatozoa
• Tribestan reported to increase the body's natural testosterone and LH levels
• Tribestan helps in alleviating some symptoms associated with male menopause
• No adverse effects
• No toxicity and side effects

Since the body's natural testosterone promotes protein synthesis and positive nitrogen balance, the benefits for the professional or the recreational athlete engaged in active training and workout, are muscle cell growth and increased body strength as well as faster recuperation and recovery from muscular stress.

• Tribestan is a completely natural non-hormonal herbal (phytochemical) biostimulator derived from the plant Tribulus terrestris L., Bulgaricum, which contains predominantly saponins of furostanol type, with prevailing quantity of protodioscin (not less than 45% in Tribestan). It is a natural herbal alternative to synthetic anabolic hormones without any clinically proven toxic effects.
• Tribestan administration leads to increased muscle mass in active sports by activating the enzyme associated with energy metabolism. At the same time it has also been reported to have the ability to stimulate some functions associated with the increase of the body's natural endogenous testosterone and lutenizing hormone (LH) levels. With the increase of the body's natural endogenous testosterone level, it can help alleviating some symptoms associated with male menopause.
• Nearly 20 years of experience with natural herbal Tribestan administration has seen no toxicity and negative effects to date.

For years, Tribestan has been used by athletes of the Soviet Bloc. The Bulgarian strength athletes have also used it extensively with effectiveness. Tribestan has passed all the drug tests at every competitive level and has been used with significant results by top professional athletes as well as by recreational sport participants with no contraindications, no toxicity and no side effects. With its good safety profile and its natural herbal origin, Tribestan is sold as a dietary supplement in many countries with little restriction on its use.

• Special attention should be given to the harmlessness of the natural herbal product Tribestan.
• No evidence of acute, sub-acute and chronic toxicity has been found during the experimental behavioral, hematological, functional, biochemical and morphological studies.
• Absence of carcinogenic and teratogenic effect.
• No adverse effects were noted in any of the clinical studies and additional research demonstrated no adverse effects on the Central Nervous System and the Cardiovascular System.

• Tribestan has also been reported to be a popular medicinal herb in Bulgaria and the East, Eastern Europe, China, India, etc. for the treatment of sexual deficiencies. Three major medical centers in Bulgaria have therefore conducted clinical studies on Tribestan effect on reproductive functions. In 1981, Tribestan was incorporated into mainstream medical treatment in much of Eastern Europe for:
• Improvement of libido and erectile function
• Increasing serum concentration of testosterone and LH
• Stimulation of spermatogenesis with increased concentration of spermatozoa, increase in sperm motility and viability

Report on stimulation of spermatogenesis

Tribestan administered to males with idiopathic oligoasthnozoospermia or with spermogram disturbances due to varicocele, has shown increased concentration of spermatozoa, increased percentage of motile spermatozoa. Increased spermatozoa motility rate and, for some cases, increased volume of ejaculate of 1 to 2 ml. In controlled studies the number of Sertoli cells increased by 40% with no change in the number of Leydig cells.

• In clinical studies on 212 patients, 85% of patients with reduced libido, demonstrated improved libido after 30 days and 94% after 60 days of treatment with Tribestan.
• For 36 patients with chronic prostatitis and reduced libido, 75% reported favorable effects at the end of the treatment cycle.
  
• In animal studies, libido and sexual reflexes were restored in 71% of subjects with complete absence of libido. In subjects with poor libido and sexual reflexes, recovery was recorded in 100% of cases.
• Treatment of patients with unilateral and bilateral hypotrophy of the testes, demonstrated enhanced libido and improved spermogram after 60 days.
• In patients with primary and secondary hypogonadism, 78% reported restored and enhanced libido with 22% reporting improved erection.

Report on increase of the body's natural testosterone

In patients with testosterone serum levels below the lower limit of the norm, the physiological levels were reached after treatment, whereas in patients with normal initial levels, the testosterone level was not significantly changed after treatment.
