At the end of the day, each of us has to determine what works best for us, at what dosage, cycle lengths and in what combinations. We typically start that process by reading everything we can find on the topic. That's when we discover that there are as many different opinions as there are people stating them. Much of that is simply because each person is different. Side effects that you find intolerable might never be an issue for someone else, and a cycle that delivers fantastic results for them might be a total waste of time for you.
