Testosterone booster?What are the affects of using some sort of testosterone booster? Does it affect the way your body produces it down the road?

I was thinking maybe if your body grows accustom to the help of the testosterone booster then when you stop using it your body might have trouble producing it again.

tuckermattTestosterone boosters don’t work in the same way that exogenous testosterone (steroids) does. Steroids are adding testosterone to your body, and your negative feedback loop will detect that you have enough test and stop producing it. Testosterone boosters how ever aren’t directly adding hormones or hormone precursors, they are just supplying nutrients that the body is lacking to make your body’s natural production more efficient. So the testosterone boosters won’t screw up your endocrine system. Your test levels will drop after you stop taking test boosters, but only back to the levels they were at before, but that’s because you don’t have whatever nutrients are in the test boosters. You can get the same benefits of a test booster just by having a healthy, diverse diet and getting the nutrients that way.

Difference between free and total testosterone?According to test results, I have very high total testosterone (although still in normal range.) even for my age group. I am a young adult.

However my free testosterone levels are slightly on the bottom half of the “normal” range.

What does this likely mean and what is the difference between the two different types of testosterone?

tuckermattTestosterone is tightly bond to steroid hormone binding globulin, a protein in your bloodstream that helps fatty testosterone to circulate in the blood better (fats don’t dissolve well in water, and the plasma/fluid component of your blood is roughly akin to salt water). Free testosterone is the unbound version that actually is available to do the things that testosterone is supposed to do. Your testosterone levels sound normal to me, by the way, but I’m not your doctor and you should discuss any concerns that you may have with him/her.
