I'm a big proponant of Sustenon. Its been the staple of all my cycles... I've done 5 cycles over the last four years. My first 2 cycles were Sus only... I put on 30lbs of LBM that year. They were low-dosers too: Cycle 1 was 250mg/EW. Cycle 2 was 250mg/E5D Each was 12 weeks long. The last 3 cycles I've done, I've stacked Sus with all sorts of shit: Deca, EQ, Winstrol, Proviron. I've always been pleased with the results Sustenon has given me.
