Post cycle therapy

Hello teacher, I came to your site from your YouTube videos. First of all, I would like to thank you very much for providing such useful information. I am on a cycle of 300mg Testosterone Enanthate and 300mg NPP (Nandrolone Phenylpropionate) per week, both Humax brand. I had one vial of each drug, and they are almost finished. I have never done PCT (Post Cycle Therapy) since I started the cycle, I have always continued like this. At one point, my psychology was very bad, I had alopecia areata, I was aggressive and pessimistic, but it cleared up from my body in 3 months and I recovered. I don't want to encounter such problems again. I will continue the cycle with one more vial of each and then end the cycle. What path should I follow afterwards? Your advice is very necessary for me. Thank you very much for your reply in advance, good work.
