Jeezus ... so much folklore out there. Many guys need to read a lot more before posting as "experts". Or at least qualify their answers. I don't consider myself an expert or a biological chemist or whatever, but here is MY understanding.
This stuff about "its self-tapering" may be true but it's not the point.
People USED to think that if you were taking high levels of test for example, that maybe if you "tapered" down somewhat, that your body would recognize that, and start once again to kick its natural test production back in.
The problem is that even when "tapered" down, there is still WAY too much test being given, too much in your system, for yor body to start to signal itself to "start up" again.
Regardless of what level of Test you were/are taking, it is necessary that ALL of that injected Test be used up for a short while, before your body will do anything at all to start back up again.
For example if you are doing maybe 500mg/week of cypionate. Your body sees that much test, and your natural test (HTPA axis, all that stiff which gets a bit more complex than I will get into) is stopped.
Now if you drop to say 400, 300 200, etc ....... the old theory was that your body would go "hm, ... that external test I am getting is dropping, maybe I should start up again ...". Thats BULL it does NOT work. You would STILL need to wait like 2+ weeks after that last week of 200 mg before you could get HTPA and natural test started up again.
So if you final 4 weeks look like this:
500 500 500 500
or
500 400 300 200
it still does not matter in terms of HTPA recovery, because your body will STILL need a good 2+ weeks after that last week before you will get your ntarual test (HTPA, etc etc etc) to start to kick back in.
So again, in that second example, it does not "sorta start back up due to tapering levels". Thats BS.
Now, since in BOTH scenarios above, you will STILL have to wait like 2-3 weeks after that last shot of test to start HTPA going again .... then the question is - why waste or lessen the effectiveness of those final weeks?
Meaning, if you had an 8 week cycle that looked like one of these:
Straight Taper
500 500
500 500
500 500
500 500
500 500
500 400
500 300
500 200

Clomid St. Clomid St.
... starting Clomid in week 11 ... then why would you bother lessening the effectiveness of weeks 6-8 by tapering? It does not help you at all! You STILL have to wait a few weeks (to week 11) to start Clomid!
Now personally I think there IS an issue with the DOSE AMOUNT causing a delay in how long you wait before taking Clomid. For example if a guy was taking 1,500 mg a week of Test, it may take 21 days for it to get metabolized enough so that the levels were low enough so that starting Clomid would actually work. If the guy was taking mayke 300mg/week he might only have to wait like 18 days or something. But thats not due to "tapering". That is just because it may taken the body a bit longer to lessen its test levels far enough for Clomid to be effective, when a very high dose of test was being administered.
So, tapering does NOT help you to recover more quickly.
Given that, then it makes no sesne, becuase it only would lessen the effectivess of the final few eeks of the cycle. And frankly, if you are going to do that (see 8 week example above) you would probably be better off just shortening the cycle anyway.
