I've heard little to no complaint about the potency of their products. The only thing that I've heard is the underfilled thing and that a lot of their injectables are painfull. I've never had any complaints except for the pain but, their stuff is definitely good, especially for the price. Now if they'd just lower that god damn BA content!
most the time people think there viles are underfilled. this is because if you fill right to the line you are overfilling by about .15 cc's. thats where the loss comes from. so if you need 2 cc's dont go right to the 2cc line, stop about a line and a half before. there stuff is not underfilled. there anadrol is great also
