i agreed with ARAGORN and SILVERFOX there r lost of factors involve not just the gear itself,
and for all i no, unless u test ur own gear thats
the only way to find out wether is underdosed and or fake stuff, it's easy to tell when is underfilled however, does not tell us is underdosed, u can also get away if u do a certain gear itself but, u must do all the necessary steps
to help ur cycle for better sucess....
