Clen and T3 confusion

[Wizeguy]

I have cycled AAS 4 times now with good success, I have never used clen or T3. I was thining about doing a good winter cycle of Test E and Deca. But would like to try and get lean in the spring.
I read Perefect Beasts Clen protocol.
I'm just a bit confused as to when clen should be used. On or off cycle?
I have heard that clen can cause some muscle wasteing.
I also read that clen shouldnt be used without T3?
Set me straight, whats a proper clen, T3 protocol and when should it be used?

Clen can be used on or off cycle,depends on your after.Both is correct.

T3 can EAT muscle,that is why many only use it with AAS.Low doses its ok,for example with HGH.

Clen can be used with T3 or not,depends what your after.
