Testosterone Enanthate has a half life of 4.5 days!

I am so sick of the copied and pasted BS all around the internet about these superlong half lives of drugs. 10.5 days for enanthate? They are nuts. 4.5 days for prop? 2 days for fucking suspension? Ludicrous. I dont know which imbecile pulled that number out of his ass, along with the rest of the half lives copied and pasted off eachother all over the net, but it is really starting to get to to me. 4.5 is the half life of Test E. Test cyp is also very close. Test prop would be far less, I am estimating ~ 1-2 days. Once a week injects is NOT enough for enanthate, unless you want sub-optimal blood levels.


proof?

Great, so you found two links (one of which doesn't even work) and now everybody else in the world is wrong? nice try.


And just to use the same websites that you used.

The half-life of testosterone cypionate when injected intra-muscularly is approximately eight days.

Testosterone enanthate (7 carbons) and testosterone cypionate (8 carbons) both have half lives of about 10-14 days, and so they are typically injected once every 10-14 days.

No, only the people that cut and pasted off the orginal idiot that said 10.5 days. try again, they both work

I guess you didnt get that :rolleyes:

This is not internet war but "sub-optimal" blood levels of test enanthate doesn't necessarily equal sub-optimal results.

I know the blood levels would be more constant if one injects test e. 2X/wk. Well, blood levels would be more constant if you injected ED as well.
As a matter of fact, blood levels would probably remain most constant if we wheeled around an IV drip of diluted test e. -- so let's all do that.

I doubt you can dig up a study which will show, that at the levels of test e. everyone takes here, there is a significant difference in results in those who are injected once per week versus those who are injected twice per week with test e. or cyp. M'kay?

sub optimal blood levels do result in sub optimal gains, if you are a newbie then you can gain without striving to get your blood levels as even as possible, but if you are advanced, then your gains are not going to be very good if you dont have optimal blood levels
 
Why do so many people take enanthate or cypionate for hrt purposes when sustanon was specifically designed for HRT and keep blood levels even?

Because you can't get Sustanon 250 prescribed in the US for HRT.

I don't know, but I kinda' think that these "bullshit discussions" are what make EF great. Peeps duke it out, then someone eventually comes up with the defintive answer. Hopefully this time it will be you, bro, and you will have added important new info to the lexicon of BB. Looking forward to what you have to say. :)
 
Sure bro, dont get me wrong.....i feel the same way..not trying to offend anyone......im just going to assemble a group of vets, and maybe 1 author who is very respected...to straighten this out.

Don't get me wrong, PJ, I absolutely respect your posts. What I meant to say is that it's discussions like this that will bring out the experts, like you, to provide us all with a definitive answer. I most certainly didn't mean to offend you. Sorry if I did.
 
Its all good man..i can be a dick sometimes... :) especially when on a cycle

Would be nice if we could get William Lwenyl ( author of the Anabolics 2000-2005 books) to comment on the halflives. He is a walking database.

which link did I post that said that? Neither.


Also, did you read the title of the thread?
 
I'm only doing 1ml so I'll stick with once weekly shots. If I was doing more than 2ml I would break it up.

on almost every steroid board with a "half life" section.
 
read: http://www.jenapharm.de/de/fachkreise/doc/fachinfos/testosteron_depot.pdf

a paper for docs about a testosteron enanthate 250mg/ml from the German co. Jenapharm; on page 3, a chart is shown where blood plasma levels are recorded (y-axis) for every hour after a single injection (x-axis).
it shows that:
- before injection, the subjects had testosterone concentrations of around 4.5 ng/ml = baseline
- maximum blood levels are reached 54.25 hours after injection at 14.31 nanograms/mililiter (page 2), this is 300% of baseline or 200% = 10ng/ml above baseline
- blood plasma levels increase very rapidly for the first 24h and stay highest for around the first 2.5 days (chart at page 3)
- half life is reached when blood levels reach around 9.5 ng/ml at 144h, 6d after injection
- baseline levels are reached after 12-13 days, this means that after 13 days the product is completely metabolized and out of the system

bioavailability and half life differ greatly between subjects (page 2): peaks have been recorded as being between 9 and 19 ng/ml; this means, that one person gets 200% baseline levels from one injection of TE 250mg while another person might get 400% = double the results.
there are also huge differences how fast the steroid is metabolized; one extreme reaches its peak at hour 16, the other extreme has to wait up to hour 92 (!) after injection to reach its (probably lower) peak.
the whole bioavailabilty (ng multiplied by hours) differs between 2000 and 3000, which means that some people get 50% more out the same injection, for the compared TE it was even 100%.

if we factor in that the number of androgen receptors also varies greatly among people one can imagine that the results of a steroid cylce do vary in huge numbers; there must be bodybuilders out there who gain close to nothing off a 250mg TE cycle while others pack on serious pounds with the exact same product.

btw., the bioavialability has an even greater variance for orals, in clinical trials plasma concentration vary up to 1000% (10 times) between subjects. If you only grow on 100mg of dbol ed while your buddy grows on only 10mg, nothing is wrong, its all within normal range.

6 days half life for TE is average, but 4 or 8 days can also be true for you, it depends on the individual.

Not true bro. My doc prescribed me sust for my last cycle. Although this cycle I got prescribed test cyp. The difference is night and day. Sust hurts bad and the cyp is like butter, nice and smoothe. I'll never touch sust again.

btw...i'm on my girl's computer....she doesn't like sust either...haahahaha

If you're doing "cycles" then it's not HRT. I didn't say you couldn't get a doc to prescribe it. I said you couldn't get one to prescribe it for HRT.

You better read your own material again. It says the half life of cyp is approx 8 days.

You should really ready your material before you try to use it to make others look stupid. All you did here was make yourself look like an ass.

(gone, no reason for it)


....And who was a trying to make look stupid? Certainly no one here. I have a problem with the misinformation posts on various sites about half lives and, therefore, injection frequency.

Arguably. My wording was, admittedly, poor.


My main point of this thread is to debunk the following crap, not start arguments that solve nothing.



"Depot steroids
Drug Active half-life
Deca-durabolin (Nandrolone decanate) 15 days
Equipoise 14 days
Finaject (trenbolone acetate) 3 days
Primobolan (methenolone enanthate) 10.5 days
Sustanon or Omnadren 15 to 18 days
Testosterone Cypionate 12 days
Testosterone Enanthate 10.5 days
Testosterone Propionate 4.5 days
Testosterone Suspension 1 day
* Winstrol (stanozolol) 1 day"
 
and this crap.....


Steroid esters
Drug Active 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

actually they are very close, enth is one carbon atom heavier, the difference is barely even worth noting, and definitely not noticeable in the body..

this makes no sense you are right, especially when the enanthate is the heavier molecule, and would therefore have a longer halflife than cyp.

No bro, cyp is heavier, and its half life is slightly longer.
 
from what i have read test cyp and test eth are virtually the same thing. one is a european version and one is an american version.

i am planning my next cycle now to include cyp but if anyone can tell any reason eth would make any difference, would be happy to learn.

I've taken enanthate twice, I wasn't too impressed with it. It didn't last too long, and like you said I wouldn't be surprised if the half life is shorter.
 
paitently waiting for the modman to give us a final call...

however i will say this:
the last cycle of enanthate i did; i did notice that if i waited a whole week before my next shot, i would start breaking out (which i do after a cycle only), if i shoot twice a week, i honestly feel better.

i know that the ester is long, but i "feel better shooting eod. i DOnt shoot an entire ml, but i don't get the sides that i wood shooting 1 time a week. No backne, calm, and strong. I interchage cyp and enan with no difference. What ever is cheaper.

Satch i think we are about the dsame size and i'll do a comp with you. you look better now, but i'm up for that 14 monther wit cha. i'm 5'9 215-220. it'd be fu n to run the same compounds and see who comes oout on top. pm me, or talk to iron god or his brother. it will be fun.
 
Im trying to get a hold of some experts. Give a man a break at least for the weekend :)
 
I prefer to reinject when half of the halflife has gone by anyway, unless i'm only doing 1ml/week like I am now.
 
benevolent anarchist said:
If it’s common knowledge then why do most people inj. cyp or enth every 4-5 days?
Click to expand...

i agree with you benevolent. 4-5 days for sure. did not agree with the poster who said 10 days at all.
 
Basal = Base
Basal levels = Base levels
*seems to me his showed that test levels returned to base levels after 10.5 or so days depending on the dose. The higher the dose the longer before returning to basal levels.
** In turn. You would start clomid therapy when you returned to basal levels. The basal levels he listed are the same you see floating around this site!
