I am a consultant in the Boston biotech community and have worked with Raul and his GSI team for the last one and a half years.  They have supplied the FDA-approved drugs that I’ve used for all of my client’s preclinical studies, from work in mice to studies in nonhuman primates.  Raul has never failed to deliver the compounds/formulations we need and has always delivered them on time and on budget.  Even last-minute changes we made in study designs, where more or less drug was needed, has not been an issue.  Raul is a wonderful communicator who consistently informed me of the availability and shipping status of our orders.  I believe Raul and GSI live by the motto “Let’s get it done! “ and often recommend GSI to my academic and industry partners.  On a personal note, it is a pleasure working with Raul and he is a super nice guy to boot.

I am involved in preclinical research and have been working with Raul for more than 10 years.  During this time, he has always been very consistent, diligent and proactive.  I cannot think of a time that he was not able to procure a comparator for one of our preclinical studies.  Raul has also provided comparators for other members of my organization and they also have been extremely satisfied.  I would definitely recommend Raul Hernandez and Global Global Sourcing Initiative for any comparator sourcing needs.

Thank you Global Sourcing Initiative (GSI)!!! My first (and only call) for sourcing needs!

In early research drug discovery, I am often utilizing hard to obtain reagents for positive controls and/or model induction in cellular assays and in vivo models. Prior to working with GSI, this was an arduous task to obtain certain reagents, much more difficult to accomplish than one would assume. GSI has helped me numerous times and I have referred them many times to grateful my coworkers (current and former) as a quick, efficient, and reliable source for your research needs!
