AAS half lives

An old post from the old site that I've saved...Very helpful and very useful:

So everyone understands the Half-Life of Gear, this is something I found through some browsing that can explain it...This can also help you to determine when you start PCT...

Half-Life can be explained as the time it takes for a substance to reach half it's level in your blood...

A practical example is if one was to inject 100mgs 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 50mgs. Again, a further 4.5 days down the line and levels would drop to 25mgs, and the value keeps halving every 4.5 days.

Drug Half-Life:

Dianabol (Methandrostenolone, Methandienone) 4.5 to 6 hours
Anadrol / Anapolan50 (Oxymetholone) 8 to 9 hours
Anavar (Oxandrolone) 9 hours
Winstrol (Stanozolol)
(tablets or depot taken orally) 9 hours
Stanozolol (injectable) 1 day
Testosterone Suspension 1 day
Clenbuterol 1.5 days
Arimidex 3 days
Methyltestosterone 4 days
Clomid 5 days

Depot steroids half-life

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

*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 it is included with a half-life of one day.

Here are the half-lives for any of the following steroid esters:

Ester 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
Laurate 10 days
Heptanoate 10.5 days
Enanthate 10.5 days
Hexahydrobenzylcarbonate 11 days
Octanoate 12 days
Cypionate 12 days
Nonanoate 13.5 days
Decanoate 15 days
Undecylenate 16 days
Undecanoate 16.5 days
Heptylate 20 days

For all you sust lovers out there note that the following esters and amounts are used:
30mg Propionate
55mg Phenylpropionate
65mg Caproate
100mg Decanoate

Testonon uses the following amounts:
30mg Propionate
55mg Phenylpropionate
65mg Isocaproate
100mg Enanthate

Note that sust and testonon are in fact different in one respect. Also note that the longest acting ester in
these has a half-life of 15 days. As Andy noted previously, 1/2 the half-life should be the optimal point to
begin therapy, thus 1 month (minimum) with testonon and sust.

I would like to point out another fact that arimidex has a half-life of 3 days. Thus an everyday
administration is not neccessary

EDIT:NEW ADDITION

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