How do natural testosterone supplements lower a man's testosterone and libido levels?

[kelkel]

What other factors affect libido?

-dopamine and serotonin are two major monoamines involved,
hence why you see a relation between drugs of abuse and sex.
But it isn't as simple as high levels equal high libido.

-estrogen plays a role; both positive and negative

To expand a little (not for Doc as he knows) the sudden influx of dopamine and seratonin at the onset of a testosterone cycle gives guys a big boost in arousal / libido, etc. Problem is guys expect it to stay this way but it won't. The body slowly adapts to it and finds it's new (albeit temporary) normal.

Other pieces of the puzzle are simple really. Hormone balance, lifestyle, stress, overall health, a hot partner....


**Re Cialis elevating test levels it does by virtue of impacting (lowering) estrogen levels slightly. I've posted studies on this before and can again here if anyone likes. Chalk another one up for one of my favorite supps.
