Tren alone is a very bad idea.Even though it does not convert to estrogen you can still get gyno...but not as easily as with other drugs.It has something to do with progesterone.You can also experience hair loss.If you are gona run tren then you need to run test as well.Tren is something like 3 times as anabolic as testosterone...but it does not aromatise to estrogen,so the gains are very solid.It is a very good drug to get you cut...and your Strength will go through the roof,unfortunately your dick might go toward the ground without test...and you will definately need clomid for post cycle therapy to kick start your natural test again,because tren can shut your testosterone production down very quickly,and when you come off you will have the test levels of a little girl..lol.If you do decide to go with it drink plenty of h20 because it is said to be rough on the kidneys,but in my opinion any drug in excess will be hard on the kidneys.
