Tren A has an anabolic and androgenic score of 500/500. It can last in your system for two to three days. It is a 19 nor steroid, and comes from Nandrolone. It is known to provide androgenic results, but it does not change into estrogen. It has anti binding properties for the androgen receptor that is five times stronger than Testosterone. Buying Tren A is very popular with athletes because it retains nitrogen in the muscles and increases protein synthesis. This is a good steroid to use in a cutting cycle. You don’t have to worry about metabolizing or aromatization or 5alpha reductase into other estrogen forms such as DHT or estradiol.
