This is the original RoidCalc © 1998-2006 SmartLabs, Inc.
The Roid Calculator
calculates the estimated blood level of different steroids, using half-lifes.
The half-life is simply the time when 100 active milligrams breaks down
to 50 active milligrams, to 25 active milligrams, and so on. The half-life
may come after a few days, or a few hours, depending on the drug.
You can use it to see how much active medicines you really have in your blood.
Please remember that the results are only approximate.
The half-lifes used below is based on several scientific studies.
included a - 5% waste factor, because we dont live in a perfect world,
and there will always be a little bit of loss when you inject steroids. On the orals I have included a -10% waste factor.
