half life?

[Ryker77]

I found this on http://www.basskilleronline.com/half_lives2.html and http://www.bodybuilding-tips.net/s23/t85.html in fact most all of the boards have cut and pasted this.
formate 1.5 days
acetate 3 days
propionate 4.5 days
phenylprop 4.5 days
butyrate 6 days
Valerate 7.5 days
Hexanoate 10.5 days
caproate 9 days
isocaproate 9 days
heptonoate 10.5 days
enathate 10.5 days
octanoate 12 days
cypionate 12 days
Nonanoate 13.5 days
decanoate 15 days
Undecanoate 16.5 days

Yet on the http://www.come.to/roidcalc those numbers are half that of the above. :-? I would hope that somebody could clear this up.

Testosterone propionate 2 days
Testosterone phenylpropionate 3 days
Testosterone isocaproate 4 days
Testosterone decanoate 7 days
Testosterone cypionate 6 days
Testosterone entantate 5 days

this guy "skyfire" says the opposite. I hate when the experts have two different thoughts. It makes it hard for us non-experts.

Re: half life?

Is he from the UK? If he is that's what Mick Hart put out so must of them go with what he says. Look around the net you'll see what I'm talking about. Hit the drug profile link in my sig it'll give you some info to work with.

Here's a good way to know if it's the half life or the active life. How long would you wait to start PCT after using one of these esters? That will give you your answer.

Re: half life?

isnt half life the time when half of the substance will be out of your system, ie 50mgs, with a 2day half life, in 2 days you will have 25mgs still in ur system. active life is how long it lasts period, that is the number you use for pct (i think - where's billy he knows for sure)

Re: half life?

Half-life is the period over which the concentration of a specified chemical or drug takes to fall to half its original concentration in the specified fluid or blood.

Re: half life?

I understand the difference between half life and active life. Wouldn't the "active life" be the better way to measure and time your injections. It is the active amount that we want to keep even.


JohnnyB I clicked on the two links you have. But they don't agree. sustanon Active Life: Approx. 21 days then I go to the roid cal put in 500mgs on day one 21 days later the chart still shows 3 it doesn't drop to 1 untill day 28 and still takes 38 days to reach zero.



My main point is that the roid cal is very popular and most use it to determine the dosage and injection times. But I keep getting various numbers that don't agree with the roid cal.

I agree with that, because that is the you need to wait before stating pct. The half life is what you want to go by for injectiom timing. Say you inject 200mg of test and the half life is 5 days and the active life is 15 days, on the 6th day you'll be at 100mg. So if you inject every 3 day your chances of keep you blood levels more stable are high then if you waited the 15 days. If you waited 15 days, you'd have some major peaks and valleys. Hit the roid calc and use cyp as a compound, inject it every 14 or 15 day and you'll see what I mean
