Question about body's response to T injections

[Stanfoo]

Say you injected Test Prop for the first time.

1) How long after the first injection will the body stop producing it's own T?

2) How long after the first injection will the body be fully cleared of it's own endogenous T?

Prop is gonna be in and out so quickly that after just one injection you prolly won’t experience any real or sustained shutdown

edit: I guess I should clarify; are you talking about after one injection or after multiple injections during the week? Prop requires daily admin and you’d be shutdown in 3-6 weeks.

The shutdown will happen within 2-6 weeks depending on the dose of T used.

Higher doses of T (200mg+) will result in a quicker shutdown of the hpta (2 weeks).

Daily administration.

Interesting that you guys said a few weeks. Everywhere else I've read people say as soon as the body senses exogenous T, shutdown occurs immediately.

The full shutdown of the hpta does not happen immediately.

Testosterone suppression of the HPT axis - PubMed

Exogenous testosterone-mediated inhibitory influences on the hypothalamic-pituitary-testicular axis were reversed following the cessation of drug treatment.

It does start shutting down but it does take time to completely shut down.

My limited understanding is that the body cannot distinguish between exogenous and your body’s internally produced T. Instead, its the high level of T that signals to suppress your natural production.
