HLCalc

Half life - How long does it take for a substance to reduce in half, in this case when administered as a drug. That drug could be any relevant compound, anabolic or androgenic steroids, Benzodiazepines, SSRI's etc etc.

When taken repeatedly the levels of each substance in blood can increase. This is not always easy to visualize given dose and frequency so HLCalc graphs it out for you.

Doctors, athletes of all sorts, and those just interested in PED's will find this useful to visualize how single or multiple compounds in various doses will affect the body.

You can set HLCalc to remind you when to take medication and you can even send & receive medication cycles so a doctor for example could send a patient an HLCalc file which can be loaded into their personal copy.

Store as many different medication cycles as you wish and add / remove drugs from the database to suit your own needs.
