Tibullus Terrestris - This is a weed that grows in temperature and tropical climates and has been used for centuries to increase libido in males Does it also increase testosterone levels as many supplement companies would have you believe? That depends on who is taking it Tibullus terrestris HAS been shown to increase testosterone levels by as much as 30%, but only in individuals who have low testosterone levels to begin with It will raise your levels to normal, but it will not raise them if you already have normal testosterone levels So, tribal’s terrestris is partially useful as a testosterone booster If you are overstrained, if you are on a low calorie 'cutting' diet or if you are recovering from steroid or prohormone use (as part of PCT) tribal’s terrestris can be useful n raising your testosterone levels Don't expect that it will give you super high test levels or significantly increased libido 6 out of 10 stars!
