If, as you say they ARE new then it's unlikely that guys will have bought them via Domestic as yet. That said DS is a highly regarded AAS site here and I'd trust them to only sell good solid products.
Something else: I've never really been a 'brand' or label kinda guy (with only a few exceptions). If there are 3 brands of test cyp, for example, and they all contain the stated dose in a nice carrier liquid then it ought not to matter what brand you use.
Agreed. Shouldnt matter
