Trenabol 200 is a long-acting injectable steroid with a great effect on protein metabolism. Trenbolone is one of the best effective anabolic compounds, promoting protein synthesis, as well as creating a positive nitrogen balance. It is an appetite stimulant and improves the conversion of proteins. In laboratory tests, it has been demonstrated that trenbolone increases protein and decreases fat deposition. It has proven to be an excellent product for promoting size and strength in the presence of adequate protein and calories, promotes body tissue building processes, and can reverse catabolism. Due to its particular ester, trenbolone enanthate is slower-acting than trenbolone acetate and faster acting than trenbolone hexahydrobenzylcarbonate. Based on its molecular structure, trenabol enanthate is theoretically stronger than either trenbolone acetate or trenbolone hexahydrobenzylcarbonate.
All contain an estrogen, ethinylestradiol or mestranol ,   in varying amounts, and one of a number of different progestogens. (Regarding the estrogen, the inactive 3-methyl ether of ethinylestradiol, which must be metabolized by the liver into the active ethinylestradiol; 50 µg of mestranol is equivalent to only 35 µg of ethinylestradiol and should not be used when high-dose [50 µg ethinylestradiol] estrogen pills are needed; mestranol was the estrogen used in the first oral contraceptive, Enovid ). They are usually taken for 21 days with then a seven-day gap during which a withdrawal bleed (often, but incorrectly, referred to as a menstrual period ) occurs. These differ in the amount of estrogen given, and whether they are monophasic (the same dose of estrogen and progestogen during each of the 21 days) or multiphasic (varying doses). The introduction of extended-cycle monophasic pills (. Seasonale) has shown that the withdrawal bleeding intervals can be decreased.
