Ive seen a few amps in my time but ive never closely analyzed them and I just got some Organon sustanon'250' amps with yellow writing...They look exactly like pics ive viewed online, but the only thing suspicious is the size of the tops of the amps....if you look very closely they slightly vary in size on top....and if u look at the levels close they are slightly different ....My source insured me that they were definitally not underdosed and if nething, overdosed and that once in a syringe would read 1 cc.....is it common for amps to vary slightly or do you feel that I was ripped off....Sorry i cant provide any pics..
