Trinabol Trenabol is a combination of three esters of trenbolone. The presence of the acetate ester allows Tri-Trenabol to display a rapid initial physiological response. The other two esters, hexahydrobenzylcarbonate and enanthate, which release at slower rates, prolong the physiological response with a relatively flat absorption curve over the duation of the injection life-cycle. Trenbolone has a great effect on 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.
