What prohromones do:
Side effects; unpredictable, hairloss, gyno, zits, hpta suppression
It can also make you less sensitive to steroids. So if you are a natural who plans to cycle, it's a very bad idea.
The only prohormones that should be considered:
19-Nordiol(spray)
4-AD(spray)
1-AD
These can offer some mild gains, but they are extremely expensive and have as many side effects as roids if not more.
They are classified as steroids in Canada, and an 8 week cycle of 1-AD can cost over 900 dollars. Canadians who use prohormones are complete idiots. Gear is just as tolerated by law and it's actually cheaper.
In the States, they should be used only because of legal issues.
It's also a good idea to buy a couple of bottles if you plan on fooling some loved ones when you put on 15lbs in 8-10weeks. If the brand is featured in a magazine with before and after pics, you're set.
