Just did a quick google search to read up on it. Not much out there about it. One place out of texas that sold it, the rest was people talking about it that were from Mexico.
The person in the video said it is safe, but my concerns are if Bayer made it why is it not sold in the US? There is nothing that I saw in a quick search saying it was USDA approved (in English). It may work short term, but how would it react to your body down the road? Take a look at DHEA and how many took it for the male hormone properties. A few years later it was discovered to lead to health problems nobody saw when it was released by USDA. Another example is the military members who are being given Anthrax shots. Some have no ill effects, others are breaking out in rashes that nobody can find the cure for. Anthrax shots were for animals and now service members in certain parts of the world are required to get them or risk being discharged for not following a direct order. It is not in the news anymore, but it is still a huge concern for many.
There are many products that are not harmful and not approved by the USDA or sold in this country, so this could be one of them. I just ask you weight the good with the bad and make sure it really is worth the risk be they known or unknown. I would hate to see anything negative happen to anybody here (or elsewhere), especially if it was a desire not a life threatening need.
