T Nation

My Blood Results (27M)

They seem okay? I’m wondering why my total is lowish, but my free is high?

Your SHBG is low, so your free T is high.

Is that good? Is free t a ratio of total?

Free T is the part not bound to SHBG, essentially. Low SHBG is not particularly great, but you get a better ratio of Total Test to Free, and E2 to Free Test.

I have SHBG on the lower end and can get away with a lower Total T level (350-400) and still have plenty of Free T in circulation. There are a great many things that can affect your testosterone levels, sleep, diet and exercise. Too much exercise and/or not eating enough can suppress testosterone.
