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 ( this is why Dbol is wasted unless it is dosed at least twice daily)
Methyltestosterone 4 days
Winstrol (stanozolol)
(tablets or depot taken orally) 9 hours


Steroid esters

The half-life applies to the ester regardless of hormone attached, for example trenbolone enanthate and primobolan (methenolone enanthate) will act very similarly to testosterone enanthate in terms of release rate.

A practical example is if one was to inject 100mg of testosterone propionate and allow blood levels to peak. In approx 36 hours time (half-life duration from the above tables) and provide'n no other injections had taken place, the level would be reduced to 50mg. Again, a further approx 36 hours down the line and levels would have dropped to 25mg, and the value keeps halve'n every approx 36 hours.
