I've see many posts about tren causing heartburn, I am cycling test E 250 e3d along with tren A 50mg eod. I am now 10 days in and 5 shots in of tren. 2-3 days ago I started noticing heartburn which i almost never ever get unless I eat some really acidic or greasy food and even then I normally won't get it. But also in the past 3 days I've noticed extremely increased sweating during training and cardio, little bit of tossing and turning going to bed, extra hot at night and the weights feeling lighter.

Once I started piecing things together I came to the conclusion that the heart burn is from the tren beginning to really start working along with the other known tren sides.

But does anyone know why tren causes heart burn?
