You can’t specify # of pills my friend. That’s like saying I’m taking X ml of Test. It means nothing. How many microgram? Typically you taper it up first week and run through second week. Stop for two weeks use an ECA and then run it again for two weeks.
The short answer is no, don’t go near it. It’s cardiotoxic and there are alternatives. Albuterol is clen’s non-toxic cousin. And we actually have clinical data regarding how to use it for fat loss. This one is a no-brainer if you care about your health in the slightest.
I used to take it before spring break trips or beach vacations. Started to shake pretty quick, never got passed 80mcg daily. Could never put up with it enough to lose more than a lb or two
