Karachi or nile sustanon ?

[Sustanator]

Right... in my experience i seem to get harder, better gains and more aggressive on karachi sus although it is claimed to be the same substance ?

i have checked both and both are legit gear... is it just in my mind or has anyone else had any experience of this ?

there is no more karachi sust, it's out of production - so Nile obviously...
