+ 8 Importance of knowing the half life of what you're using or going to use for your cycle.
Half Life Of Steroids
Half life's are a very important thing and should also be understood. Knowing what the half life of the steroids you plan on taking will help you plan out the cycle so all the compounds will be out of your system at the same time. This way you know exactly when to start your PCT and also to make sure you always have testosterone in your system while on other steroids.
For instance lets say if the half life of the test you are on is 2 weeks and the half life of another steroid you are taking is 3 weeks, then you should stop the longer one a week before the last shot of test. Orals have short half lives so they can be ran up to pct time in most cases while the test is working out of your system.
Active Half-Life
Oral steroids
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
Deca-durabolin (Nandrolone decanate) 15 days

-
Winstrol (stanozolol) 1 day (Technically Stan Depot does not have a half-life simply due to the fact that it's UN-ESTRIFIED! It contains microcrystals that will dissolve slowly and once they've all dissolved the levels of the hormone will fall pretty rapidly)

This post I am sure was meant to be helpful but it is full of several errors. So before you copy and paste something or give your input. Do some hardcore research and back it up with links. There have been thousands of tests done to detect the carbon life in blood plasma levels and in each test the findings typically vary. You have to realize that the "Esters" or carbon life can be longer or shorter depending on the injection site. Also the ester itself can have a carrier oil that may allow for longer absorbing times. Here is a classic example of a test that will show you how it's not as simple as the above. http://jpet.aspetjournals.org/content/281/1/93.full.pdf or http://www.ncbi.nlm.nih.gov/pubmed/10229906?dopt=Abstract Both links will show your times are off and this why it's not as easy as just throwing up some guestimates and have pertain to everyone in every instance. You may also have a guy or girl who has hypothyroidism and the T3/T4 duration may be completely off so it varies.....Just saying..........
NorthernTrustExcellent post.. good for you bro..
@ buddy below.. People make posts for the benefit of others. I could'nt care less about Karma points..
No offense I was just adding to the harsh reality that what we think we know one day can change the next. I learn knew things everyday and just wanted to add that your post while meant to help had some inconsistencies from what I read and it's really not a one size fits all type of chart.
Seen so many of these copy and pasted half life posts and they are almost ALL wrong...why do people still bother to paste other forum posts without doing their own research? Karma post?
Well I can tell you that aromasin does not have a half-life of 27hrs in the male body. Published med shows it's a little under 9hrs. In females it's 27hrs.
:-O
Seriously? Well wtf am I taking it eod for then? Who hasn't anyone shared this with us? C'mon man! Post up. Is published meds reliable enough to jump in on the idea?
here ya go nitti, its from the journal of endocrinology and metabloism
http://jcem.endojournals.org/content/88/12/5951.full
Grazie signore! Would you mind writing a short description in your own words on this topic and post the link with it in the appropriate section (PCT/Anti-E)? I got 3 points for ya. Seriously we need that info out there to read
all finished nitti, just as you asked. i broke it down in laymans so it didnt miss its mark with anyone. hope you like
Thank you
i will, right now.
there was a great post to this, ill see if i can find it for you nitti, it was a medical study for men using AAS.i believe.
MetalgearI tried to be slick and deceive the mods. I knew it was going to be a challenge ,but I prayed to the steroid gods. My posts were generic and my persona polar opposite. A perfect plan of deception boosted my confidence. Then I got comfortable and lazy soon after. This was my fatal error, it would turn to disaster. My intelligence failed me , my gut guided me wrong. Now I feel like I got reamed by a monster sized Dong! Follow the rules you won't suffer my fate. See I'm genuinely remorseful, but now it's too late. Now I'm locked out of the house and peeking inside, at the laughs , jokes and gear talk from all of the guys
NorthernTrustI've seen several different time values for almost everything listed.. None we're more than 24 hrs difference. most were a cpl hrs at most..
The point of the post wasn't for you guys to discuss a few hrs on blah blah is different than you read somewhere else or what ester is faster on such and such.. You may very well be right, but the reason for the post was to hopefully give people a benchmark to refer to when they're planning a cycle and to properly incorporate their post cycle regiment.
From one meat-head to all you other meat-heads i can safely speak for us all when I say "big balls are much better than having a couple of raisins for nuts."
For more advanced users that don't have a good post cycle therapy (pct) included in their regiment, when you hear someone say " hey that looks like a thimble in a birds nest" you'll wish you took this thread serious and guarantee you will afterwards.
Cheers Lads
ClassyChassisStrange that cyp is longer than enan.... I've seen slightly different values over time, but these are all close enough to get you in the ballpark at least. Good info!
I've seen this one before.The only problem I see with it is the prop and phenylprop having the same half life.
56tooI believe I just read somewhere that prop is 3 days and phenyl is 4.5 days
I have seen different charts of prop being anywhere from 1 to 4 days.It seemed 2 days was the most popular.So.I'm not exactly sure.But it should be less than phenyl because of the extra ester.
Good info. Nice to have it all in one place. +1
