You probably can get away on a one week cycle using esters like prop or winny but for what reason would you do this, just so you don't shut down?? You're running it for one week, what kind of gains do you expect to make from one week on?
I also didn't see the source link mention this type of cycle tbh...

I found the gentleman who advocated short-burst cycles, 2-week on, 4-week off: Dr. Bill Roberts.
"Cycles are longer than effiicent if they have substantial parts of them at a point past a point where gains usually tail well off; or yielding impaired recoveries and thus worse losses; or being so long that there is no hope of taking advantage of how some periods of training can be especially productive whereas doing everything the same and/or aiming for equal muscle-building at all times is not as effective.
So for long term results such as you are looking for, I think going past 8 weeks is non-optimal. E.g., three 8 week cycles per year do better than two 12 week cycles, with total weeks “on” and total usage being identical in the two cases.
The two-week cycles do give really fast recovery. It’s not that there is no HPTA shutdown, as there is during the two weeks, but the pituitary is immediately ready to respond to LHRH instead of so to speak having to be awakened from sleep (in more precise speaking, having greatly lowered LHRH responsiveness), and the testes are also immediately ready to respond to LH.
While if HCG is used in for example an 8 week cycle then the testes also are able to respond well to LH immediately, there’s nothing that in like manner avoid reduced responsiveness of the pituitary.
As for the hypothalamus, I don’t know if it’s more responsive to discontinuance of increased androgen after 2 weeks than 8 or if it is the same either way.
Anyway, recovery is very fast, and with frontloading the body absolutely is ready for an excellent growth burst."

HPTA is a chain and cannot be reduced to a single gland. Sometimes you simply shutdown a part of this chain, this is called primary or secondary hypogonadism.
For example, if your testes become non-responsive (due to Leydig cell desensitization) you will be still producing GnRH and LH&FSH but you still won't be producing testosterone because your Leydig cells simply became tired of LH stimulation and having some holiday to relax..
To understand what I mean, you should get bloodwork very frequently to watch your pituitary closely when you start a new cycle (also do the same for PCT). If you do that, you will just see that nothing happens instantly. Some ring of this chain becomes inefficient slowly and the others follow it. I am sure there are scientific papers and experiments on humans about HPTA shutdown but too lazy to find them at the moment.
Interesting, thank you. A friend of mine actually took pregnenolone and recovered from suppression caused by 11-keto DHT. This part in Dr. Roberts' post stood out to me: "The two-week cycles do give really fast recovery.

A 500mg cruise is for advanced lifters that are already on the upper end of their potential muscle development
A cruise for most others is usually 150-250mgs
Personally, I believe doing short burst cycles is just going to send your hormones on a rollercoaster ride with very little net gains (if at all. ESPECIALLY if it's one week cycles) to show for it.
Plus consider the source of your information that you linked. It's a website trying to sell you stuff (which I am confident is fake steroids).
Once again, welcome to the forum. A lot of great information here and knowledgeable people.

Thanks for the welcome. Here's something posted by Dr. Roberts regarding a 2-on, 4-off cycle.
"Program
Throughout the first five weeks: 50 mg/day Clo (two capsules), except Day 1 is 300 mg in six divided doses.
In first two weeks, 200 g/day protein more than usual, but hold fat and carbs moderate enough to avoid significant if any fat gain. In the following four weeks, diet the first three, and diet or use maintenance calories for the fourth, in all cases keeping protein at least 180 g/day.
Day 1: 100 mg (200 IU) TA in morning. 10 mg D five times per day in divided doses, which might include middle of the night if I awake briefly enough to have a pre-made Met-Rx. Cyt: 125 mg (half tab) on arising and 62.5 mg six and then twelve hours later.
Days 3-11: 50 mg (100 IU) TA/day, 250 mg Cyt as above, and 50 mg Diana as above.
Days 12-14: No TA, but otherwise same as days 3-11.
Weeks 3 and 4: Diana 10 mg on arising, and 10 mg four hours later. Cyt ½ tab on arising, and oxandr 20 mg on arising.
Week 5: same, but on basis of blood test, Cyt may be dropped if estradiol levels were below normal.
Week 6: Clean, unless T was not above normal in blood test at end of week 4, in which case Clo use will be continued in week 6.
Supplement use: In weeks 3-6, Androdiol 300 mg one or 1.5 h before workouts – not in the evening. If in the morning or early afternoon, an additional 300 mg after workout would be okay. Ephedrine and caffeine "
Here's a picture of week 1 and week 3 from the case-study.

"Jim has succeeded in retaining his strength gains, and even on improving his bench press, and has lost as little weight from his peak as could be expected (5 lb) considering that he lost ¾ inch from his waist in weeks 3 and 4. Overall he is now 8 lb heavier with a waist that is a half inch smaller, which probably represents a loss of about three pounds of bodyfat. I certainly hope that Jim will get a skinfold measurement at the end of week 6 to further quantitate these results.
He suffered no observed side effects except increased acne and a slight increase in irritability during the two “on” weeks, which might also have been caused by increased stress he was under at the time. Even blood pressure, which often rises during a cycle, remained normal at all times."
