Hey all. I see alot of poeple not getting the full benifit out of their gear, at least from what their cycles indicate, and wanted to post the half life times for different stedoids. I see 10 week cycles with test-e/deca and its a waste since DECA takes a minimum of 16 plus weeks to benifit from it. Or running EQ for 8 weeks, or npp every three days.
So here is a list of steroid half life to help you understand the duration time of different Steroid Half Life's Steroid Half life's - anyone new to steroids users may be wondering what this means, even some current steroid users may also be wondering what this means. So here in simple terms you can read and hopefully understand all about steroid half life's and what this term means.
Basically every drug has a half life, 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 life of Deca. The half life 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 life's.
