i'd run hcg at the end of the cycle, i never let the testes get small i like using it during cycle as well. but if you haven't use it at the end while you are still on to bring them back to size. i would run 50mg clomid and 20mg of aromasin for pct, 20mg nolva ed can be used as well but its not necessary in my experience. run the clomid for 3-5 weeks. just like muscle i am not saying derma wouldn't work but i also use what doctors prescribe and what works for me period. if doctors start using derma i'll try it.
