4 full weeks is weird. perhaps u got tren e or something.... by 2.5 weeks i really feel it. most ppl feel it by a week but others, like myself, take longer. but by 4 weeks it should def be there. maybe its really underdosed? just because u have a good source doesnt mean he will always have good shit. any source can turn at any time ya know?.......

why not just brew some fina and compare it?
