You won't get any results from it. Any "good" results will just be placebo effect.
It's either your test levels are normal, below normal (in which case a doctor will prescribe you what to take), or you are significantly high due to steriods or prohormones.
Aside from that, trying to increase your test levels legally is a waste of time if your test levels are already normal.
Go out an eat a truckload of chicken at KFC or tons of biggie burgers at Wendys. The protein and calories there will actually do more for you than taking Trib.
If you are really insanely serious about getting good gains, stick to a diet that's high-calorie, lots of protein, good fat.
