Calculating test levels with sust

[size]

At that addy you can see how you test levels will be with sust. it can really help plan when you should inject in trying to keep levels constant.

i'm thinking of the importance of the decanoate ester in sustanon , cos there is something called sustanon 100 available which doesnt have decanoate in it . would this absense of decanoate make this combination diff ? if so how ? anybody got answers ?

I can't use it because I don't have Excel. Is there another way to view this file?

You either love 'em or you hate 'em..

I starting this business of using mathematical models to estimate the life of the ester... This was years ago.. and today, I am still quite impressed at how well this SIMPLE model can be used to generalize what blood tests likely would show...

Unfortunetly, nobody can manage to COPY the formula that correctly.. This is a perfect example... The model is incorrect and does NOT give an accurate representation...

Those who don't know me.... I'm a hell of a nice guy...


Why re-invent the wheel?
Simply ASK me!!! I don't withhold information.. I'll tell you everything I know..

What's the fomula, if the model is incorrect?

You can use something simple like Enanthate or Cypionate...we won't complicate things with multiple esters.

That excel calculator is a rotation-of-tires-away from becoming a very useful tool for BBer's. It takes me a handful of minutes or so to put a graph together the old fashioned way.. Computer science wasn't required for philosophy majors..

The simple formula for exponential decay of the ester is:

y=yo*e^(ln(1/2)*t/h)

Where
y= current amount
yo= initial injection amount
t= day
h= half life (same units as t.)

This formula alone however, is not sufficient to estimate fluctuations in blood levels from AAS.

The value "y" tells us only the amount of esterified (inactive) AAS remaining in the depot.. It gives the false impression that when 1000mg of TE is injected, all 1000mg are active right away, and decrease from there. This isn't the case..

In order to have a reasonable model for what's going on, I found that "mg T de-esterified/ day" plotted on the y axis is more useful than "amount left in the depot"

y axis= (y2-y1) and plotted as a funtion of time, in this case, x1 would pair with (y2-y1).

LOL!


Thanks bro.....very useful information. Maybe I'll see I can get a little program together.....if I can find some time.....to bad I have to work for a living. I could get a lot more done in 45 hours per week! Hahahaha
