Hey all,
I wanted to have an approximation of how much of a molecule I had in my body at anytime, so I made a mathematica file to run pharmacokinetics models.
I am happy to share in case anyone is interested.
I made it for the supplements I take (Ephedrine and Caffeine), but you can easily modify it for any kind of supplement as long as you know the half-life and doses.
Note: I cannot attach this file to the forum (format not permitted), so if you want it, just ask me to send it to you.
