any reference to 'G-13' has to be taken with a good dose of skepticism ... there is every probability it never even existed, and could be only 'urban legend' ... I have a strain of my own, that 'supposedly' contains 25% G-13 genetics ... the key word here is 'supposedly' ... whatever it is, it is very potent, but I would not assume to guarantee it's the genuine article ... anything called 'G-13' should be pretty powerful stuff, whatever it really is ... :smokin:
