So im starting my first cycle in a couple of weeks with a buddy, he talked me into taking sustanon 250 with him at 750 mg a week with 3 shots a week. He's also taking anavar as well but i was thinking about taking deca instead because i heard that its good for your joints and ive had a couple of knee injuries. I was thinking about just taking 100 to 200 mg a week of deca, whats your guys thoughts on this? are they good to stack or should i lower the dosage? Thx guys
