What's right?

This article covers the half-life's of the most commonly used steroids, esters and ancillary compounds.
Oral steroids
DrugActive half-life
Anadrol / Anapolan50 (oxymetholone)8 to 9 hours
Anavar (oxandrolone)9 hours
Dianabol (methandrostenolone, methandienone)4.5 to 6 hours
Methyltestosterone4 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.
DrugActive half-life
Suspensionwithin 1 hour
Acetate1 day
Propionate1 day
Phenylpropionate1-2 days
Butyrate2-3 days
Valerate3 days
Hexanoate3 days
Caproate4-5 days

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 providing 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 halving every approx 36 hours.

Schering indicates Testoviron Depot half life is 7 days and Pfizer Cyp 8 days. HTF we suppose to know for sure with all these different numbers around.

Why I LOVE prop ( 4.5 days) - damn-I love the quickies!!!!- plus with Z -I have no pain and can pin EOD

I was pinning prop ed a while back I don't miss that.I'm sticking with longer test esters for now on and never go above 750 mg

Methyltestosterone4 days

Thats a typo.

And could this format be any more garbled?

ED is a tough one for me-above 750 is also tough.I find that EOD works for me

I wish I could get some consistent half lifes though, for instance Pfizer reports cyp is 8 days and Schering reports enanthate is 7 days. Then you have to consider the actual test after the ester is 72% for E and 70% for Cyp. So if I wanted to duplicate the results of Test Suspension 100mg ED I would have to have a release rate close to 100mg daily which would mean 100mg of actual test time the half life times 2! My choice would be 250mg En so I could start with 8ml and then 4ml E7D. Front loading seems to make sense.
