Ostarine is in another LEAGUE from DAA. My buddy who was natty before Osta put on 10 lbs with really good strength increases (20+ on major lifts) and fat loss. He looks unnatural now. I took osta after a cycle for PCT and found it propped my strength up a lot, now that I'm off I lost quite a bit.
DAA has excitotoxicity concerns and isn't even THAT great a T-booster. My vote is osta, hands down.
