Half lives

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) 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

* Long-chain esterified injectable steroids are the most unreliable in terms of determining an actual clearance time. Their extremely low water solubility and high affinity for fat give them the ability to be stored in small amounts in body tissues for many months after use. These are the most dangerous types of drugs for tested competitors to use, particularly when being administered heavily in the off season.
** Short or medium chain esterified injectables are cleared from the body more rapidly than long chain injectables, however are still somewhat inconsistent in terms of calculable clearance times. It is safest to use such compounds only in the off season, provided this season protects the user from drug testing.
*** Oral steroids are the most reliable in terms of rapid clearance time. In many cases the athlete can safely use such compounds three weeks out from a drug test and return a negative result. The time frame of 1-1 1/2 months was provided as a guideline for maximum safety. The short chain esterified injectable testosterone propionate was included in this category due to the fact that testosterone metabolites will only cause a drug test failure if they appear in unusually high quantities (in relation to epitestosterone metabolites). Should agencies adopt procedures that look for the actual esterified compound in blood, this would be moved to one of the categories listing other small to medium chain steroids
