Thanks herm...

Thanks BigHerm! Good shit.

Sorry to do this to you again Herm, lol, but those numbers are simply not correct, although you often see them. 4.5 day half life for propionate? Also 4.5 days for phenylpropionate? 12 days for CYP!!!?? lol. We'd have to wait months to start PCT at optimal levels if it was 12 days! lol. The funny thing is that the actual half lives are closer to half of what is posted (for most, not all). Here is a link with a chart that you can see the test enanthate drop to "half" the peak level after about 5 days:

And just to be clear, the "half life" that we are concerned about here is the level in your system falling to "half" of what it was at it's peak concentration. It may well be that for medical purposes and TRT effectiveness it has a 10.5 day half life or whatever, but that info is completely useless for someone running a cycle like us. You need to know when it reaches the halfway point so you can get the levels back up.

So, to sum it up, Herm is not wrong, lol.... I just exalained things in a way that relates to what we do with the drugs, rather than in a TRT sense.

Ya but isn't that graph tested at 140mg a week? Also dropping half in half of the active life still means your not low enough for you to start recovering?

Ummm, say that again? lol

it doesn't really matter what doseage as it will drop at the same rate always. So, if you start higher with a frontload, you can maintain higher levels throughout. There is so much bogus info on esters all over the internet that it's ridiculous. Just google "Testosterone Enanthate real half life" and see what kind of bunk shit people post. I saw in a list like this that listed the following:

propionate - 2.25 days
phenylpropionate - 2.25 days
acetate - 3 days

lolololol, those are all wrong.... acetate is shorter than both and PP is the longest, not much shorter than enanthate in fact. If you look at the carbon chains you can figure that out (I'm not saying you in particular Herm, I'm speaking to the community now, lol).

[LeanHerm]

From what I understood pp was smack dab inbetween prob and e.

Lol sorry what i was saying is if a guy let's say taking 140mg which is like a trt dose and let's say he's in the 500 test range vs a guy taking 600mg a week with let's say 1500 maybe more but you know the routine. So if candidate a is stopping to go do a pct that his levels would hit a low enough number for hpta to start coming back before candidate b because of the test levels? So with that bein said is the ester already gone and its just the elevated test levels in the blood reducing?

[Get Some]

yes, now you're onto something! The blood level is what's important here. The more you have in your blood at the end, the more it makes sense to run prop for the last few weeks. If you are just running a low dose (even though that's dumb, lol) then you should be fine.

Another thing I wanted to mention as well is that fact that I see some people saying they are going to run a low dose of test with a high dose of something else so their natural test levels won't be suppressed that much... lol, yes I'm serious. I know most of you see the problem, I just wanted to make sure y'all knew about this.

Most every steroid is a derivative or cousin of testosterone and will shut down your natural test levels. Otherwise, you'd see guys running cycles without any test all the time. On the other hand, if you are thinking about running a steroid cycle, you may want to run a clomid or letro only cycle first to see how much you can raise your natural test levels first.... just a thought mates
