Question:

For example sake say I take 100mgs of a substance.
The half life is 1 hour.
After an hour I take another 100mgs of the substance.
So I now have a total of 150mgs of active substance.
Does this mean in one hour I will have 75mg of active substance?

Or does the new added amount have its own active half life?

To make it simple Im asking if adding more mgs just gets tacked onto the total in your system.. .and ur system cuts the active number in half every hour based on my example.

Thank you.
