I almost thought either my tren was severly underdosed or bunk except the gains threw that worry out the window but it seems after mutiple uses of tren I no longer get certain sides I orginally had at the beginning. Like first couple cycles with tren I had trensomnia, waking up every 2-3 hours, cardio endurance way down, tren cough, and strange taste in mouth after every tren ace inject. And now the only sides I get is heartburn/stomach issues and only at 1g a week or more and prog gyno flare up. Anyone else become immune to sides of tren or heck any steroid for that matter?
