I believe you need more, and I believe there are better options to nolvadex and clomid... Although there are people who tend not to agree with me... And there are people who run nolva or clomid as their only PCT drugs and are very successful.
I for one don't like the side effects, and neither were very effective for me as the only means of PCT.
Here are my current thoughts on PCT
HCG+Arimidex or Aromasin+Sustain Alpha+Unleashed+Post Cycle+Forged Post Cycle
Nolvadex and Clomid are optional in that stack.
It isn't cheap, but worth it to me.
