If you tried Erase and DAA together before with no real results I'm just curious as to why you want to run again with another compound? I don't know much about osta, hanging on to a bottle for a while as I still don't know a whole lot about it lol. This is just my opinion but I would think that if you didn't notice much from Erase/DAA you probably wont get anything drastically different from adding osta. I don't really know tho, good luck.
