Both deca and tren are 19-nors, and bind to the progesterone receptor...and this is why everyone says not to take the two drugs together, to avoid bad progesterone induced gyno.
But...I have never seen ONE person post that they ran the two together at the same time, and I have never seen ONE person, post they ran the two together, and got gyno from doing so.
Are people just regurgitating the same old, same old in regards to using these drugs together? I am thinking about using the two...is it too risky, or is everyone just too **** paranoid?
