using Arginine /citrulline for circulation

 Hey guys, im new in the forum. im planing to do LL not sure with who ( DR G o Betz), anyways.  I saw a horrific story even pulmonar embolism I wonder if Anyone has taken before "Arginine /citrulline",  I used to be so fitness and the trip stated when I was so young a doctor recomenden this protein at night because it helps producing HGH.
 some things I noticed:

-Loosing some fat and increase muscular mass.
-sexual organs increase.
-My hair start to hair un volume.
-After the gym or be exhausted, with Arginine I just felt like new, with so much energy and bigger muscles.
-mi skin felt with colagen


  I know it help in the training and but not sure if helps with LL, o even help with pulmonar embolism.

¿any of you guys have tried this or any other kind of protein?

It works quite especially effect is doubled if you exercise a lot
