Now I really dont have the knowledge about what equations to use for half-lives and what is right, but I just dont know if I trust that calculator. I have ran a chart for a 10 week test enan cycle at 600mg/week using the equation given in this thread plotting release of different esters and ran it out to 3 weeks past the last shot, and the test levels in week 13 were down to around 100mg/week, just when recommended to start pct. According to the calculator given, running the same cycle at 10 weeks 600mg/week, cycle ends day 70, pct starts day 114...44 days later?!? Like I said earlier I dont exactly know the correct formula for figuring this out as there seems to be several out there, I am just really doubting this one.
I understand how the amount of esterfied hormone will build up in your body over time, but there will be a certain point where it will stop climbing, which using the equation I got from Skye, is around week 9-10 with test enanthate, figuring a 10.5 day half-life, so the absolute longest a shot of test enanthate could even be active would be 21 days, no matter if it was a 500mg shot or 2000mg shot, in 10.5 days half of the shot will be released and used up, then 10.5 days later the rest will be gone. I am sure there will still be some lingering around for awhile after that, but not enough to keep you suppressed 7 weeks later I doubt.
If someone with a better understanding of this subject could chime in and back me up, or prove me wrong, that would be great

Remember, half-life follows a logarithmic scale and not a linear scale. Example:
2000 mg of Test Enanthate is present. 10.5 days later, 1000 mg is present. 10.5 days later, 500 mg is present. 10.5 days later, 250 mg is present. 10.5 days later, 175 mg is present (etc.) The PCT calculator does appear to be correct in its theoretical calulcations.

I don't know what equation you are using but peak levels of esterified testosterone usually happen within 6 weeks. Just take a look from your cycle on the calculator, view the cycle from day 1 and you'll see the levels peak much earlier than your other calculator devised.Originally Posted by NateDawg
Anyways, a few of your questions are also answered in the FAQ on that page. Give it a read, its fairly short.

This is true, but in my experience x is always less than it should be. If you take a 1000mg shot of test e. on day 0, the value is shifted such than in 10.5 days only 400mg remains instead of the predicted 5. More is hydrolyzed initially and the calculation does not account for this phenomena. It is a matter of common experience because most fellas shoot more often than every 5 days with this ester.Originally Posted by Klaus
It is absurd to leave a 40 day gap in between a cycle and PCT! Try to get your statistics down to baseline before starting pct, but if not, start anyway because the commonly used SERMs have a long t1/2 too and require time to accumulate if not loaded up front. This is why I always take a long, 2 month PCT. There's no way around it. Sometimes I even bridge with a low-suppression oral the few weeks for a smoother transition. ACT has changed that now. It will solve this issue permanently.

More is hydrolyzed initially? What are you basing this statement on?Originally Posted by DR.D
Most fellas do shoot more often than 5 days with enanthate. Why are you stating the obvious?Originally Posted by DR.D
I've said it before and I'll say it again. That is why you should not go cold turkey off long esters.Originally Posted by DR.D
08-28-2005, 10:23 AM
You kind of answered your own question. If more is not hydrolysed initially, then why shoot more often that every 5 days? Because in the real world, that calculation needs a special factor in it to account for this. It is good as a guideline though when planning doses for a cycle.Originally Posted by bulkmuscle

You shoot more often than 5 days with enanthate so that your testosterone levels don't "seasaw" significantly and additionally to maintain a higher level of testosterone.Originally Posted by DR.D

Doc, are you in agreement with the idea that for long runs of test E, your PCT should indeed start up to 6 weeks after the last shot? If so, it seems like running something or some things (much shorter acting) for most or all of those weeks is advisable?
08-28-2005, 01:36 PM
No, I totally don't agree w/ 6wks. Unless you can plan it just right, then that's fine. And yes, you can cut your shots at 6wks, or whatever, and finish off with an oral, or switch to a shorter acting ester. But 2 or 3 wks tops if you don't wanna blow the cycle. Just do a longer PCT. I have never agreed that recovery is impossible unless the last mg of ester is gone from your system. I have successfully cheated and bridged too many PCTs to believe that and can tell you otherwise.Originally Posted by milwood

I gave the link to the calculator I was using bulk, did the link not show up? I did read the FAQ, and it really didnt answer any of my questions, if it would have, I probably wouldnt have asked them lol.Originally Posted by bulkmuscle
I agree with you on how it would be best to not stop cold turkey from long esters and run they cycle out a few more weeks with either an oral or a much shorter estered injectable.
08-28-2005, 01:57 PM
I agree with the idea of not going off a long ester like that, but if you do, there is no point to PCT if you don't wait the proper time, as you will simply just get shutback down.Originally Posted by DR.D
08-28-2005, 02:01 PM
I am pretty sure DR.D already knew this he even said first off that most guys shoot more often than every 5 days, which agreed with what you said, so I see no reason to argue that.Originally Posted by bulkmuscle
When he was explaining more is hydrolyzed initially than what the equations tend to figure, that explains why you would shoot test enan more often than every 5 days, yet you disagree with him stating that more is hydrolyzed than what the equation gives. If you agree with your equation being 100% correct, you should be able to get away with shooting every 5 days and keeping blood levels fairly stable with that dosing protocol since 5 days is about half of the 10.5 day halflife. So do you agree with your calculator or not? I am not trying to start any heated arguments, just want to figure out what exactly is right

Like I mentioned earlier, I have no idea which way is right or how to even set up an equation for something like a halflife from scratch...algebra was my downfall, if you guys cant tell lol
08-28-2005, 02:21 PM
Would make sense that having exogenous test in your body would not hinder recovery b/c your body bases its shutdown on test production based on your natty levels, right? Therefore, if you've got a small amount of exogenous test left in the system--the body has no clue it's synthetic--so long as your test levels are within normal range, supression will no longer continue and recovery will be underway, right? Therefore, I'd assume even if you had like 100mg or so of Test E (etc) in your system, recovery would begin. A TRT dose of 100mg test/wk gives test levels around low-mid normal range, so I don't see any reason supression would take place (or at least not much supression) at that level.Originally Posted by DR.D
I don't believe HPTA supression is not dose dependent, personally. I don't know why I read so many people who think that hormone--> body == shutdown, regardless of dose, when it seems evident dose plays a role.

I'm not trying to cause a ruckus eitherOriginally Posted by Nate Dawg
He said that if you inject 1000mg of enanthate, in 10.5 days there will be 400mg of esterified enanthate left. Then he gave no reason for this "magical" disappearance of 100mg. I just wanted to know what his reason was. A half-life is a half-life. Nothing changes about it just because it is your first shot.
On the topic of the article you posted. I should probably note that the time to start PCT is all dependent on what your base testosterone level is. I used a baseline of ~550 ng/dl from one of the sources listed on the page. 100mg of esterified testosterone resulted in a negligible change from baseline levels. So if your levels are naturally much higher, then you'd want to start PCT sooner. And if you don't know your baseline, you're really taking a shot in the dark with when you start PCT.

t1/2 is hte time it takes for "half" of the hormone to dissappear. Its not linear, either. I forgot the formula, but its definitely not a linear decay.Originally Posted by bulkmuscle

I don't know what your t1/2 is suppose to mean. I didn't say it was linear either.Originally Posted by kwyckemynd00

"Magical", OK, now you're starting to sound a bit derogatory. Please do not use fruity terms like that with me again. You can use whatever equation you like in your 'magical' world where the skies are purple and unicorns run free, I could really give a **** less.Originally Posted by bulkmuscle
Anyway, if you must know, the t1/2 is biphasic. So no, a half life is not a half live. Each metabolite of test has a different half live and the enzymes that cleave the ester are not steady. That's why more hydrolysis occurs initially. If it didn't, 1 shot ever 5 days would achieve steady state in just a few weeks. Plus, much of the hormone leaves the sight of deposit only to be sheltered in adipose tissue or converted into other esters of the bodies choosing. You are trying to make this black and white. It's not. Research the issue if you really want to know, I don't have the time to offer links or do it for you (because I already know), but please be respectful in the future. I was only trying to help elaborate on your equation when you decided to get ****ty. I really don't take much ****.
