If you are noticing aggression at those higher levels, then your decision to lower your dose back to 150mg/wk makes sense.

There is no benefit in tapering down. You can drop immediately down on your next dose. Skipping a dose would not be recommended, as this puts you at risk of dropping below your therapeutic level with a return of your hypogonadal symptoms.

Higher Testosterone doesn't directly cause this, the emotion hormone and the basis of "roid rage" is Estrogen. The higher you go past 200mg a week the more transference to Estrogen you run the risk of having. Testosterone's side effect chance is a steep inverse bell curve when increasing dose.At that level, you should very much be taking an AI to combat this. For reference, we sometimes have Estrogen sensitive men on 1mg-2mg a week for ranges 200mg & below. It's likely you would need more to combat your Estrogen issue, though there's more side effects with AIs the higher dose you take, and it sounds like you're sensitive to it.It would probably be ideal to come down in dose or add an AI if you don't have one. Barring that, you can increase injection frequency and switch to subcutaneous injections to also lower T spikes, but it will only do so much at 300mg a week.

Tapering down with Testosterone doesn't matter all that much, as your natural production is incredibly small anyways. Keep in mind the normal adjustments for men are 10-20mgs at a time, not 150mg. Edit: Also, don't skip weeks. You have nearly no Testosterone production right now, you'll feel terrible. Just go back to a dose you're comfortable at.

You might be able to tolerate 160mg, maybe 180mg, maybe 200mg. But you won't know your sweet spot by making large swings. It sounds like this is just a blast cycle, but when you come down it would be good to try and see if you can dial in your cruise to a level where you don't need to blast to get the majority of the same benefits with less side effects.
