Question about long cycles?

[abiacb]

I have read a handful of articles stating that prolonged testosterone use will stop increasing libido, however the articles never explain why. Is it something hormonal or is it a dopamine issue? For that matter is it even true at all?

Never heard of that.

When you inject synthetic test your normal testosterone production shuts down during this period and then you restart your system it can not always bring it back to 100%. And then you cycle again and again etc. It can lead to trt.
Longer cycles you do the harder it is for ths body to recover naturally. But if your injecting test then your libido is fine and often increased greatly. Assuming your estro is in check of course.
