For a cutting cycle, Eq would be much better. Although I hate clens they work good as shit. From experience, I feel that for a cutting cycle a test along with an eq that gets shot everydat or every other day works best. For some reason something like test prop and ganabol 4 to 7 times a week works better than Boldenon and cyp once or twice a week. This is as far as cutting goes in my opinion.
As far as sex drive goes, I think everyones body works differently. I think clen did not help my sex drive when I was on it. Although I never heard of it decreasing sex drive I think mine might have been.
Hope I helped
