Boldenone-U is an oil-based solution of Boldenone Undecylenate for IM injection delivering boldenone in case where the prolonged dose titration and slow drug release are desirable. It is indicated for Osteoporosis due to androgen deficiency in hypogonadal males. It will also cause the muscle cell to store more nitrogen than it does release so that a positive nitrogen balance is achieved. A positive nitrogen balance is synonymous with anabolism and assimilates a larger amount of protein than usual.
