I am currently using the Testanon 250 and am very happy with it. Sust/EQ/Dbol is a great cycle---consider getting some proviron down there if you want to keep the bloat down and keep a handle on sides. In regards to the Loeffler Sust, I have never used it, so my opinion on it is not as credible as the one above---I just assumed it was Test and maybe a little underdosed at most. I have had good results with the Tests in MX, Ttokkyo sust, T200, organon, Primoteston...so I assumed it would be ok for your 1st 5 weeks. Hopefully you can exchange it or get your money back.
