Analytical Testing Services

Seven Star Pharmaceutical services also offer routine testing on pharmaceutical solids at highly affordable pricing without compromising on its quality.  We believe that affordability in drug development costs would have twofold effect: (i) Encourage pharmaceutical companies to pursue their innovative research ideas (without thinking much about the involved cost) to discover new medicines that help patients, and (ii) Services accessible even to small pharmaceutical companies with limited resources and funding.  We guarantee the results will be delivered in timely fashion.
