Spanish Testex from Spain can still be located on the black market . This product is made by Altana Pharma ( formerly Byk Leo ), and is packaged in 2ml dark glass ampules with yellow silkscreen lettering . It comes in two doses , containing a total of 100mg or 250mg of steroid . Testex has always been a high-risk item on the black market , so be careful when shopping . Note that the first letter in the lot number ( such as T -001) should rest below , to the left of the company name ( Altana ). Fakes often misplace these digits . If the T (por ejemplo) were to rest directly below the A in Altana , or to the right of the A , you definitely have a fake .
