The active ingredient in Trena-V is one of the most well known ingredients for shredding fat, increasing mass, and increasing aggression. Trendione, the active ingredient, is a well documented precursor to real trenbolone, one of the most anabolic substances known. The conjugated double bond system found through the central portion of the steroid backbone allows the molecule to flatten out and bind tightly to the androgen receptor. The molecule is also a glucocorticoid antagonist owing to its ability give a vascular, shredded look. Glucocorticoids are a class of steroids that increase water retention and give you a more bloated appearance so antagonizing this receptor is a welcomed effect.
