Hi, I am a 3D CG Artist and I had done several muscle deformation animations for some massaging machine promotions. If what you want is something I can do I want to help.
So I just need you to message me and describe what exactly you want; is it injection/healing animation, or blood circulation, or bone/muscle deformation?
To sum up, this link is for my 3D animations showcase, mostly mechanism animations but you can understand what I am capable of and the quality I can give.
