I've completed ME2 and developed all upgrades except for 'heay muscle tissue' which requires '1 heavy dermal tissue upgrade'. I must have missed that somewhere - I bought every shop on Citadel, Omega, Tuchanka and Illium out and took care on every one-time mission.
What is the place to obtain the heavy dermal tissue upgrade?
