Roid Calculator

Home > Roid Calculator

The Roid Calculator calculates the blood plasma 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 'roids' 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.

I have 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 roids. On the orals I have included a -10% waste factor.
Here is the half-lifes, you can change the values if you want:

Testosterone propionate days
Testosterone phenylpropionate days
Testosterone isocaproate days
Testosterone decanoate days
Testosterone cypionate days
Testosterone entantate days
Nandrolone decanoate days
Drostanolonom propionate days
Metenolon enantate days
Boldenone undecylenate days

Note: Sustanon250 is based on this for each amp:
testosterone isocaproate 60mg
testosterone decanoate 100mg
testosterone propionate 30 mg
testosterone phenylpropionate 60mg

Note: Sustanon100 is based on this for each amp:
testosterone isocaproate 40mg
testosterone propionate 20 mg
testosterone phenylpropionate 40mg

InstructionsEnter the amount (in milligrams) per injectionday and then press Calculate. In the 'Total' column you will see the total mg of roids in your blood, if you click in the 'View active' box and then 'Calculate' it will show you how much of the esters that have been released, and is 'active'. Press Clear if you want to set the values to zero. By default it will show 8 weeks (56 days) , you can change this value. It's also possible to change the half-lives if you want to use other numbers.
