There is no such thing as growth through site specific injections. The hormone is released into the blood stream through hydrolosis of the ester. The unbound androgens circulate througohut the entire blood stream untill the bind with carrier proteins or androgen receptors. The hydrolosis occurs within the blood stream. Furthermore, the resultant irritation of the oil can interfere with workouts and hinder hypertrophy. The pumps would be great, but pumps are not what cause muscle growth... pumps are only the result of an increase in cellular fluids. Where this is normally a sign of increased nutrients into the muscle cell, the pumps from site injections are from irritation analagous to a blister that occurs on the hands whenever periods of friction occur. D-bol increases water retention within the muscle and the friction of contractle proteins expanding and contracting during a workout can cause retention in the muscle cell resulting in a non-benefical pump that is potentialy detrimental to muscle growth.
