Myoglobin is a muscle protein and hence it is produced in muscle cell(fibroblasts) cytoplasm on the ribosomes.

Myoglobin and hemoglobin are hemeproteins whose physiological importance is principally related to their ability to bind molecular oxygen. Myoglobin is a monomeric heme protein found mainly in muscle tissue where it serves as an intracellular storage site for oxygen. During periods of oxygen deprivation oxymyoglobin releases its bound oxygen which is then used for metabolic purposes.

Myoglobin (Myg) has been intensively studied for many years in relation to protein structure. Myg is widely thought to be exclusively expressed in oxidative myocytes of skeletal and cardiac muscle, where it plays a role in oxygen storage.
Undoubtedly the richest source of Myg protein is in the muscles of mammals such as whales and seals that undertake extended breath-hold dives. However, Myg is also expressed in human oxidative muscle, and it has long been known that Myg expression is up-regulated in response to increased demand for oxygen or during hypobaric hypoxia.
