Personally i was a massive skeptic of Janoshik for years, so last year i took 3 vials, pulled of their label, the plastic tops with label and sent him 3 vials i labeled 1,2 and 4, told him tell me whats in the vials.. i knew what should be in the vials, but he had 0 reason to know what i sent him...
vial 1 was labeled as primo 100mg/ml came back as Primo 101mg/ml
vial 2 was labeled test c 200mg/ml came back as Test C 205mg/ml
vial 3 was labeled test e 300mg/ml and cam back 286mg/ml
Tried the same with some GH and TB-500 same results... so yeah i believe his tests, now we cant know if dealers send in vials with correct product and then sell relabeled oil. but i know now that my source for the time being is real.
