    An important consideration when planning a steroid cycle, in particular the timing of dosing to be administered, is the active half-life of the drug being employed. The half-life may be defined as the time (t) the level is half of the starting level of a given compound; at time 2t, the level is a quarter of the starting level, and at time 3t, the level is an eighth of the starting level, and so on.
    This information is vital in the timing of the dosing when attempting to achieve a more stable blood concentration, which leads to greater overall results and maintenance of gains. Some fluctuations of concentration levels are acceptable, and are also mostly unavoidable, but should be kept to a minimum.

    This article covers the half-life's of the most commonly used steroids , esters and ancillary compounds.

    Oral steroids
    Drug Active half-life
    Anadrol / Anapolan50 (oxymetholone) 8 to 9 hours
    Anavar (oxandrolone) 9 hours
    Dianabol (methandrostenolone , methandienone) 4.5 to 6 hours
    Methyltestosterone 4 days
    Winstrol (stanozolol )
    (tablets or depot taken orally) 9 hours

    Depot steroids
    Drug Active half-life
    Deca -durabolin (Nandrolone decanate)
    Durabolin 15 days
    Equipoise 14 days
    Finaject (trenbolone acetate) 3 days
    Primobolan (methenolone enanthate ) 10.5 days
    Sustanon or Omnadren 15 to 18 days
    Testosterone Cypionate 12 days
    Testosterone Enanthate 10.5 days
    Testosterone Propionate 4.5 days
    Testosterone Suspension 1 day
    * Winstrol (stanozolol) 1 day

    *Winstrol depot does not actually possess a classical half-life because it is un-esterified. Instead, the microcrystals dissolve slowly. Once they have all dissolved levels of the drug fall very rapidly. It is still an important consideration, and we have included it with a half-life of one day.

    Steroid esters
    Drug Active half-life
    Formate 1.5 days
    Acetate 3 days
    Propionate 4.5 days
    Phenylpropionate 4.5 days
    Butyrate 6 days
    Valerate 7.5 days
    Hexanoate 9 days
    Caproate 9 days
    Isocaproate 9 days
    Heptanoate 10.5 days
    Enanthate 10.5 days
    Octanoate 12 days
    Cypionate 12 days
    Nonanoate 13.5 days
    Decanoate 15 days
    Undecanoate 16.5 days

    Drug Active half-life
    Arimidex 3 days
    Clenbuterol 1.5 days
    Clomid 5 days
    Cytadren 6 hours
    Ephedrine 6 hours
    T3 10 hours

    A practical example is if one was to inject 100mg of testosterone propionate and allow blood levels to peak. In 4.5 days time (half-life duration from the above tables) and providing no other injections had taken place, the level would be reduced to 50mg. Again, a further 4.5 days down the line and levels would have dropped to 25mg, and the value keeps halving every 4.5 days.

    your half life on var is incorrect according to the anabolics 2004.

    "Like virtually all oral anabolic /androgenic steroids , oxandrolone does not have an exremely long half-life in the body. Although we do not have exact calculations on this, we can point to a study published in the Journal of Clinical Endocrinology and Metabolism investigating (among other things) blood levels of oxandrolone in response to oral dosing of the drug. Researches noted that measurements taken 10 hours after administration do show a steady elevation of the drug in the blood stream. Between the 10-18 hour mark, however, drug concentrations fell 73%. Such a drop in an 8-hour window indicates a pretty rapid metabolism of oxandrolone, and suggests that at least two oral doses would be needed per day..." - William Llewellyn
