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

Ancillaries
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.

What about Halo?

just curious, didn't see it there or missed it.

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
