SAMAR Laboratories?

I have recently picked up some gear from a company call SAMAR Laboratories from Spain and was wondering if anyone has ever heard of this company and could give me any info. on their products/reputation, etc. ? I picked up a Test blend made by this company called Aratest that comes in a 20ml vial and contains 200mg/ml of test cyp. and 100mg/ml of test prop. but I question the quality of this stuff. After inspecting one of the vials closely I found some tiny black particles dispersed in the oil and I don’t want to chance anything. I also have some Winny from the same company that comes in a 20ml vial and contains 50mg/ml. Another Test blend that SAMAR supposedly makes is called Supertest. What should I do? Any help would be appreciated.

Anybody out there???
