Clomid is used to restart your natural test production faster then it would on it's own. The reason this is so important is when you stop the anabolics you will go through a period when you are neither making natural test nor taking a synthetic test. The body is left in a state of catabolism, and muscle tissue gained will slowly be lost depending on how long it takes for your test production to restart. Clomid speeds this up. Now that you should understand what Clomid is used for, I also tell you that years ago very few people used it, and there were big mofos then too. What was done is a slow taper at the end of a cycle. While Clomid is better, if you have none, taper off whatever you're on as slowly as you can.
