This product itself is a stack. You are getting 3 steroids. Test E, Tren E and Methandriol. This is a strong set of drugs and I would be sure to dose accordingly, being safe not to go too high. Tren E can be hard to handle for some when your blood levels are high. Methandriol, the 3rd compound in this product is foreign to me. I have not used it. I have also not seen anyone use it. The only info I have is from a google search, which would lead me to believe it can be high on side effects and hard to control. So if you do use this, be careful. Be sure to use an AI and start lower, the build over time to ensure you are handling it well.
