OK bro a typical dosage of 250-1500 mg of tribulus per day is good for a Bodybuilder. It should be taken every day for 8 weeks. The typical dose is 3 capsules daily for people under 90kg and 4-6 capsules for people over 90kg. It is active in the body for approximately 8 hours. So you need to take it 3 times per day to ensure that your body continually releases luteinizing hormone, which results in testosterone production. Once you have used Tribulus Terrestris for 8 weeks, the body will no longer continue to produce excessive testosterone. However, after ceasing the use for only 2 weeks, the body will respond to it again. The 8 weeks-on, 2 weeks-off schedule can be continued indefinitely.
