When planning a steroid cycle, it is important to know how long the steroid stays in our body. So we can avoid dosing errors and ensure a relatively stable concentration in the blood and this information is also needed to know when we deploy substances to restore production of testosterone after the cycle.
The length of stay of most drugs in our bodies (also anabolic steroids are included here) is called an biological half-life. It is a figure that tells us, after which time the amount of the substance in your body is reduced by half. If anything has a half-life 5 hours and we will take 100 mg, so after 5 hours we have still 50 mg, after 10 hours 25 mg, and after 20 hours only 6.25 mg. This time can be influenced by different form, because the same substance have halfňlife in the form of oral and other (usually longer) in injectable form (an example is stanozolol and testosterone undecanoate). In the chart you can see the status after administration of 200 mg testosterone enanthate (the y-axis is mg and the x-axis are days after application).
ORAL FORMS (tablets)
|Anadrol/ Anapolan50 (oxymetholone)||8-9 hours|
|Anavar (oxandrolone)||9 hours|
|Dianabol (methandrostenolone, methandienone)||4,5 – 6 hours|
|Winstrol (stanozolol)||9 hours|
|Undestor (testosteron undecanoate)||4 – 6 hours|
|Deca-durabolin (Nandrolone decanate)||15 days|
|Trenbolone acetate||3 days|
|Primobolan (methenolone enanthate)||10,5 days|
|Sustanon or Omnadren (test. mix)||15 – 18 days|
|Winstrol (stanozolol)*||1 day|
|Testosteron suspenzia||1 day|
* About winstrol we can not talk about classical biological half-life. Due to the slow dissolution of crystals, due to the fact that it is used Stanozolol esterified, blood levels are maintained at approximately constant level, and dissolution drop suddenly.
