Tren is just going to give you sides. It's the price you pay for such a potent drug. Lowering the dose to 125mg a week will reduce sides, but will also greatly reduce gains. Jmo and experience having used it many, many times. You just might not think the results are even worth it trying to lower it so much that sides are all but gone, if that's even possible with tren
That said, I read an article once that showed tren at a dose of 75mg a month still produces results, but you know how that goes...
