For sure, tren in general can cause issues. Put that on your gut and its worse. Lots of people get stomach acid from tren. I wonder if one brand is stronger or if you are dosing it higher. Be careful with this. Your gut is so important to health and to making progress. You could try Tums and or Pepcid but really thats just a bandiad. If you find issues with this, I would see if you can find another compound to fit the goals and try that.
