An MD biochemistry in at GMC, Mumbai is highly regarded among medical aspirants. The value of the degree depends on the person taking the course, his interest in the field, and his goals. 

One of my friends recently completed his MD in Biochemistry at GMC Mumbai and today works in a corporate hospital. Another friend, having completed the same course, works at private labs. Several others work as assistant professors. Some fortunate ones have even opened their own labs.

The scope of this course therefore depends mainly on you. To open more doors of opportunities, you can take seminars, and journal clubs, teach UG students, do internal assessments, and also do some research work. GMC receives huge grants from the Government for the research work. 

So make a wise decision after considering all factors.
