Many atheletes find boldenone the better choice for bulking. Due to its effect on vascularity it is mostly used for cutting, but if you had a drug that increased your appetite like boldenone does, would you really use it to lose weight? It makes more sense to use it in a stack with a testosterone ester like enanthate or cypionate for good gains, instead of nandrolone. Sort of as a base. It aromatizes less than nandrolone and doesn't have that pesky progestagenic effect either, and because it increases appetite it would provide you with the means to an end in terms of gaining weight. 300-400 mg a week of boldenone with 500 mg of sustanon or 500 mg of testosterone enanthate would form an incredible stack. Even for those who prefer deca, adding a small amount of boldenone will go a long way in improving appetite. But boldenone is stronger than Deca, mg for mg, as well as safer and less suppressive.
