could almost guarantee if the test is dosed at 400mg/ml , and u are splitting that into 2 injections ( 200mg/ 1/2ml ) that's most likely your problem . Gear dosed that high hurts like hell . I remember when I was pinning tets like that , every time I did glutes or quads , the area would get knotted and realy hard , then for a good few days I lost all mobility and could hardly walk and bend . was realy bad
