Tweet4-OH Deca™ is highly anabolic and only mildly androgenic. It provides excellent size and strength increases with little to no water retention, and therefore imparts a hardening effect on muscle as well. Estrogen related side effects are not a problem with 4-OH Deca™ and in fact, this amazing compound has even shown mild “anti-estrogenic” effects! The true beauty of 4-OH Deca™ is that it can be incorporated effectively into either mass or cutting cycles where it can provide a synergistic effect with other PH/PS. Used on its own, or in a stack with other compounds, 4-OH Deca™ is capable of contributing to major physique transformations!
