Tren-FX

I was originally going to buy Havoc but the place where I bought it (Nutrition-X) doesn't have it in stock anymore. The guy recommended Tren-FX. I've heard of Tren so I figured I would check it out but I have to admit I'm a little worried because I can't find much information on it, online. I did read a comment from someone saying that it is likely to cause Gyno. The thing I liked about Havoc was that I experienced no side effects except for some mild acne. Can anyone share their experience with this product? I asked the guy if this was "stronger" than Havoc and all he said is that it's a different chemical but there is a hierarchy - for example Superdrol is much more risky than Havoc. Does this compound produce wet gains?
