Check out this AE half-life profile of various drugs

that spreadsheet didn't work...anyone have one that does?

Panerai, what about the 9 carbon atoms in the Phenylpropionate ester.

It's not a fact, but that's how I see it:

Propionate has streight 3 carbons chain, which basically, should be equal approx. half life of 3 days. Sinse, most of the steroids picks up in blood in first 24 hrs, let's make it 2-3 days.
Phenylpropionate is made by addition of benzene group, which is C6H6 and is not streight, but cyclic carbon stucture, so we can't say that Phenylprop will prolonge half life, the way streight 9 carbons would do, most likely benzene's group would work more like one or two added carbons(in sense of increasing solubility)
So, it will give us 3-5 days of half life, which agreed with anecdotal evidence from users of Durabolin, as opposite to Deca-Durabolin.

Thanks for clearin it up.

ORALS ARE SOMEWHAT INCORRECT
AMENDMENTS I KNOW WITHOUT EVEN LOOKING
IN ALL CAPS

Drug Half-Life:

Arimidex 3 days - TRY 50HRS.. MEAN
Clenbuterol 1.5 days- TRI-PHASIC- THOUGH 36HRS FOR THIRD METABOLITE
Anavar 9 hours- BIPHASIC 60-90MIN FOR PARENT DRUG- METBOLITE 10HRS(CLOSE)
Stanozolol (oral) 9 hours- PRETTY SURE THIS IS ALOT SHORTER
Methyltest 4 days- SUPER 17AA
Stanozolol (injectable) 1 day
Clomid 5 days-
Dianabol 4.5 hours- MORE LIKE 1.5HRS
Testosterone Suspension 1 day- FUNNY- MUCH SHORTER THOUGH IF SITE CRYSTALLIZATION- LONGER

Here are the half-lives for any of the following steroid esters:
SOME OF THESE ARE OK, BUT WITH ESTERS PARENT COMPOUND EFFECTS RELEASE.. IN ADDITION... INJECTION SITE, INJECTION VOLUME PLAY A BIG ROLE.
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
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



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.

Macro, what do u mean about methyltest being super 17aa, and how does that effect its half-life?

 

[macrophage69alpha]

Nimrod,

Sarcasm.... the half life of methyltestosterone is 2.5-3hrs

 

[Nimrod25]

Thats what I figured.

 

[panerai]

Macro, Dianabol 1.5 hrs?
How long does it take to even get digested, and don't forget that it's 17-AA, so it will have to pass liver multiple time, before being metabolized. I think, 3-4 hours is more correct.
BTW, if I take it 2 hrs, before workout, it boosts me greatly, if 1 hr, no effect whatsoever.

 

[macrophage69alpha]

time to uptake will vary- though usually time is 30-90min- depends.. with food , without food, crush and hold under tongue or in between lip and gums(quick and good)

hoewever the half life of the drug in your system (different than half life of esters for injectables- drug half life is very short) with respect to dbol is apprx 1.5 hrs

so your reaction is with in the norm-

Half life varies- these numbers are the mean

Does anyone know the half life of GAC's parabolan copy? I can't get out the bottle now, the ester isn't exactly Hexanoate, it is a long word that begins H-E-X.

I would like to know how far in advance of clomid therapy I need to stop the GAC parabolan. I was planning to stop it 3 weeks before (at the same time I stop EQ and cyp), and then continue with tren acetate, prop, and winstrol for one more week.
