Tren Hex 100 by Geneza Pharmaceuticals is an injectable steroid which contains 100mg per ML of the hormone trenbolone hexahydrobenzylcarbonate. Parabolan consisted of the same ester combination. Bodybuilders usually follow a twice weekly dosage regime to be enough in keeping steady blood levels. Trenbolone is the most powerful steroid in use by bodybuilders today. Tren, as it is often called, is both highly androgenic and anabolic. It is chemically unable to aromatize, and therefore produces no estrogen buildup. This, along with its high androgenic properties, makes the muscle produced by this drug very hard and defined. Trenbolone was also used in cattle implant pellets, where the substance was used to increase the lean mass of the cattle, while reducing the fat on the animals. Kits became widely available on the internet allowing bodybuilders to convert these pellets into injectable solution. Fina, as this homebrew oil was often called, quickly became a favorite of steroid users, like its relative, Parabolan, had done many years before. Tren can produce all common androgenic side effects. Although this steroid can't convert to estrogen, some users experience problems with Progesterone related side effects, similar to those seen with products such as Deca Durabolin or Durabolin. Users sensitive to these issues may prefer to add Cabaser to their cycles. Tren is not recommended for women as masculizing side effects are almost guaranteed. The typical dosage range for this substance is 300-700mgs a week for a period of 6-10 weeks.
