FFS mate are you joking. your starting posts on MD after pm'ing several pm about courses and not listening to any1 saying you cant feel 900mg test.
you dont know what training program ure following so god knows what ure diets like and ure wanting to start adding in peptides as well.
If you are starting dc why not get into the program first. then maybe see if you can find out if ure test is actually working as you said you havnt gained or got sensitive nips in 4 weeks which basically means ure diet is pants.
