Just got generic blue tops from a very well know China supplier. I assume they are 10iu bottles from the quantitiy that was sent. They look like any other generic blue tops but on the safety cap it says "goldpep". Has anyone ever gotten these before? Also, I guess I am just uneducated, but I always thought there was powder in the bottom of the vials. This appears to have a thicker substance on the bottom. I extremely trust my supplier, have never gotten any anything bad from him, but I am very new to growth.
Any help?

Thanks!
