I've been doing research and it pretty much seems to be what I'm looking for. However, it concerns me seeing as already I have high blood pressure. not dangerously high, but high nonetheless. Would this cause me any problems? I'd be too scared to up the dosage too much so would 20-40mcgs for two weeks yield results?
Another thing is how do I know when I have found a trustworth site to obtain it?
Last thing, the alternatives on the main site (clen -alt in particular), are they effective, will they give me similar results? Or am i better off just getting the real deal?

Sorry for the long first newbie post, trust me I'm very new to this whole thing, and i appriciate all the help.
