Ok if you are taking clomid to get your test levels up you are not on this planet. It is used, like tommybono said, in women to make them ovulate and in men it stimulats the FSH and LH levels so that they will get a sort of kick start after being supressed. Now if you were to take it during a test cycle then yes it would help with your natural test count as well as the test you take there for giving you more test for your buck, but as a solo cycle you are not going to see anything as far as gains go.
Peace out
