What are your stats? And I would run an Aromatase inhibitor (AI) with that cycle. Aromasin 12.5 mg ed. It will keep the estrogen related sides to a minimum. I would also start the deca a week or two before the Sustanan, which will ensure that the deca is sufficiently out of your system when you start your pct 21 days after your last shot of Sustanon (sust). I also assume you have a pct planned as well. If not, keep reading on this site before you start any cycle.
