just off top of head
anavar is bi-phasic- 1.5 and 11hr avg
the ester half lives are off.. and one should keep in mind that those are averages that will be affected by both injection volume and site.
clomid has a 5-7 day half life
nolva a 7-10
after extend use, 3-4wk, these become more like 7-9 and 10-14

Oral steroids ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Active half-life
Anadrol / Anapolan50 (oxymetholone) ------------------------ 8 - 9 hours
Anavar (oxandrolone) --------------------------------------- 9 hours
Dianabol (methandrostenolone , methandienone) -------------- 4.5 - 6 hours
Methyltestosterone ----------------------------------------- 4 days
Winstrol (stanozolol ) ---------------------------------------- 9 hours
(tablets or depot taken orally)
Depot steroids ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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 - 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 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Active half-life
Formate ----------------------------------------------------- 1.5 days
Acetate ----------------------------------------------------- 3 days
Propionate --------------------------------------------------- 4.5 days
Phenylpropionate --------------------------------------------- 4.5 days
Butyrate ----------------------------------------------------- 6 days
Valerate ----------------------------------------------------- 7 days
Hexanoate --------------------------------------------------- 9 days
Caproate ---------------------------------------------------- 9 days
Isocaproate -------------------------------------------------- 9 days
Heptanoate -------------------------------------------------- 10 days
Enanthate --------------------------------------------------- 10.5 days
Octanoate --------------------------------------------------- 12 days
Cypionate ---------------------------------------------------- 12 days
Nonanoate ---------------------------------------------------- 13.5 days
Decanoate ---------------------------------------------------- 15days
Undecanoate -------------------------------------------------- 16.5 days
Ancillaries ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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.

Prop should have a 36 hour half-life, it clears in 3 days
some of these half-lifes look way off to me... Enanthate
for example should be a 4.5-5 day half-life...

yep - it gets confusing when you say "Active-Half life", they are two different things.
