Does the guy you're taking the gear makes it himself.Depending on that compound there are some with specific colours, like tren(golden like colour) ,deca ,etc.Depending on the oils he uses this colours may vary ,for example from what i've saw tren may vary from redish to light amber.If you trust him and he is the maker i don't see any reason for him to make fakes ,cuz bulk powders are rediculously cheap.
