Well you have to do whatever works for you, and that's it.
Our bodies are all different, and react differently to different drugs.
Some of us can get by without PCT... When I was younger, before elitefitness, I never knew about a PCT. I would go on cycle, HCG all the way through, then come off and train hard. Then I learned of people who starting using SERMs PCT. I tried it and it seemed to further complicate things for me. Slight depression, loss of libido, and erectile disfunction. I didn't respond well to it.
Now with HCG, Armidex and the designer supps that are out now... I feel great coming off cycle. And I feel my recovery is just fine. But to me, the HCG has always been a key ingredient.
But again, you do what works for you. For instance, I can't take anavar... It makes me lethargic and kills my appetite. That doesn't make it a bad drug, just a bad drug for me... There are plenty of people who really like it... And there are people negatively affected by it.
PCT is just the same. Find whatever works for you and roll with it...
However, if you are finding yourself: depressed, loss of libido, losing muscle, or unable to recovery, etc... Then it is time to try something new and different.
