Tunica and Ligament stretching

Hi everyone, I would like to know whats the difference between stretching the tunica and the ligaments. I was reading in other forums that it’s important to stretch your ligaments first,why?
-What are the best stretches for getting everything out of my ligaments before I begin stretching my tunica?
-What are the best tunica stretches?

I’ve been PEing for 2 1/2 weeks now and I haven’t seen any growth, just increased hardness. I’m not trying to come off as impatient but I’m eager to learn more and I’m definitely faithful to PE.

Please help me!

Have you read the TGC Theory? Might be a good place to start research. (see my signature)
