I have to say, if you look at the ingredients, there is only one supplement that you should not take – the one ingredient "Pyrroloquinoline Quaternary", or PQQ. The PQQ is the main ingredient in many other supplements. It contains some of the most dangerous chemicals in the body. We don't know what it does to us, and how it can damage our body.
The PQQ is a synthetic chemical, which is not really natural to be found in nature. But this chemical is actually more than 100 times more toxic than its naturally found counterparts. And it is used in an unapproved form in many products sold as muscle building aids. I was told by a friend who was working in an orthopedic hospital that the PQQ is very addictive, and if you take too much you'll go through a detoxification process, which can be dangerous. There is a PQQ in every vitamin and supplement that I have tested. And it is one of the most addictive substances on the planet. It is not legal, and it is not regulated as such. In the book " The Purity Myth " by John Walker, he writes about the use of PQQ in "bio-medicines, a new type of dietary supplement that contains a compound that is a potent natural pain killer and anti-inflammatory agent.
You might think Musculin Active works wonders. At least this thesis comes up, one notices the count...
