Post honeymoon TRT crash period?

I can't find much info on this. How long does it take to shut down natural T production after starting TRT? I'm assuming once your body senses outside T, it shuts down natural T. Right before this happens there should be high T levels, meaning natural T combined with outside T creating a temporary super T level. This would be the honeymoon period?

That said, right after natural T is shut down, TRT T levels must still be quite low since it is still building up, even lower than your previous natural low levels. This would cause a severe crash worse than you felt before starting TRT. How long to build new T levels higher than old natural T levels? If it takes months to get T levels higher than old T levels you could stay in crash mode for months, correct? Is there anyway to quickly boost T to avoid a long term crash period post honeymoon?
 
Typically, at the initiation of TRT, blood is drawn at the six week mark to determine serum levels and correlate those values with subjective response - how the patient feels. That doesn't mean the dialing-in process is over; in most cases (though not all) there will be protocol adjustments made as the patient and doctor work to achieve success.

It takes time. There is nothing linear about androgen replacement; we are all different. Starting "low and going slow" (as the late Dr. John Crisler so often said) is the best way to approach the entire process.
 
Long term T crash post honeymoon phase? I don’t think it works like that.

Many men produce ~5mg/day of test. If you’re injecting double or triple that amount you’re not going to be low. For example your levels may go from 300 to 900honeymoon to 700.

So you may have a honeymoon, but not a crash? What does it feel like before the honeymoon? Do you feel better and better then hit a honeymoon then drop a bit? Or do you go from feeling bad straight to honeymoon?
 
The semi-euphoric feeling of the honeymoon very likely has little to do with some magical balance of T levels, and a lot to do with dopamine response to the initial introduction of exogenous T.
 
You are exaggerating the effects of the honeymoon and far too fearful of the so-called crash. You may well experience a short, pleasant ride when TRT starts, a ride that will fade, but serum levels are going to be in flux as your therapy unfolds. You are not being plunged into a state of hormonal misery for an indefinite period of time.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
