I don't believe that reputable, world-renowned pharmaceutical companies market products that could be dangerous to your health. It all depends on who uses them, whether they're aware of it or are a raving lunatic with self-harm intentions.
I've been researching the matter, and I've noticed that many people consider PM dangerous, if not lethal. It certainly is, but if taken in doses that go well beyond their awareness, they gulp it down by the bucketful every day, trying to force and speed up the effects of breast development. They'll inevitably have serious problems, or worse, they've asked for it, and then they even complain.
I'll start with the dose below the minimum, that is, 1 capsule a day, to "test" how my body reacts. I'll do it for a week or two to gradually get my body used to it. If all goes well, if not, I'll Problems, so I increase the dose to 2 capsules a day, and then I stay stable with that dose.
I don't go beyond that, for any reason.
