Does tongkat ali shut down natural testosterone production?

No evidence suggests it does. Shutdown is what happens with exogenous hormones, meaning testosterone taken from outside the body, which signals your own production to stop. A herb with modest effects on a few markers is not doing that, and it is also not a substitute for prescribed treatment.

Do you need to cycle tongkat ali?

There is no evidence either way. No study has tested whether taking breaks makes any difference. The cycling protocols circulating online are invented rather than tested.

Is there a loading phase?

No. The trials used the same dose from the first day to the last, with no higher starting period.

Tongkat ali or ashwagandha supplements?

They have different evidence bases and are not really competing for the same job. Ashwagandha has more human trials for stress specifically, while tongkat ali's clearest findings are in men who started with low testosterone. Neither is a standalone treatment for low testosterone.

Can tongkat ali cause acne or hair loss?

Both are reported anecdotally, but neither was established as fact in trials. If a supplement were substantially raising androgens, those effects would be plausible, which cuts both ways: their absence from the trial data is also a question about how much is really happening.
