Hi,

Do not know if this is the right place for this thread.

I am planning to use clenbuterol for 7 weeks (min: 20mcg max 140mcg) and am seeing many reviews about possible permanent heart problems (ex:heart enlargement).

Do these problems come from just one cycle or from permanent long term use please?

I would like replies from those who tried clenbuterol and therefore can talk from experience.

thanks
