Exogenous testosterone to natural testosterone progression chart

[tarmyg]

Hi guys,

I anyone aware of any studies (or other type of data) where they have measured the how much exogenous testosterone can be introduced into the body without affecting the natural testosterone production?

I am thinking like this. I your natural testosterone production is 100% and you introduce 1% of exogenous testosterone does that mean the natural is now 99%?

Note quite sure I am being clear enough!

Thanks

The main issue would be the negative feedback loop from estrogen. That is far more suppressive than high test levels. But no, you can't get any real benefit from supplementing your natural T with exogenous test without shutting yourself down.

I see, so any Test that goes into your body, no matter how small, will potentially do a complete shutdown? There is no partial shutdown for anyone who would take 10 mg/week? I am not trying to figure out how to have the cake and eat it to more interested in how this works.

Thanks

I didn't say that. But once you start adding a useful amount of testosterone to the body, there will be some negative feedback to balance it out.
