Steroid Half Lives: A proven guide on how to calculate half lives

Steroid Half Lives

Steroid Half lives - anyone new to steroids may be wondering what this means, even some steroid users may also be wondering what this means. So here in simple terms you can read and hopefully understand all about steroid half lives and what this term means.

How to calculate half lives

Basically every drug has a half live, steroids included. If for example, you were to inject 200mg of Decadurabolin once weekly, for 6 weeks, how would you know when you were "off"? Would you be "off" when you had finished your last dose? You would be able to calculate this from the half live of Deca. The half live of Deca is around 14 days. This means that 14 days from your last shot of 200mg of Deca, your blood levels of Deca will contain 100mg of the steroid. Another 14 days from then, i.e. 28 days from last dose, your blood levels will contain 50mg of the steroid. This amount then keeps halving every 14 days. Therefore you can clearly see that when you finish your cycle, even though you are not putting any steroids into your body, you may think that you are now "off", however you still have, and will still have for some time after your last dose, "active" blood levels of the steroid. Therefore you can plan what to use, how long for, and how long off your cycle, based on these half live's.

This chart is so wrong.
How does testosterone enth get labeled with a 10 day half life yet only has a 7 straight carbon chain.

Propionate 3 straight carbon chain yet labeled a 4.5 day half life.

Cypionate 8 carbon chain labeled as a 12 day half life.

None of that even makes sense. You physically cannot have a 12 day half life on an a carbon chain. It’s simple chemistry.

It takes the human body 24h to remove one ester carbon with a standard deviation of +/- .25.
