well i believe i ran 40mgs a day for about 3 months,along with 1900mgs of sust,800mg of eg per week,i brought the halo in about a month in and the strength went through the roof,some joint pain,to be expected,i would'nt run any more than 50mgs a day on it,also break up your dosing,morning-afternoon type deal...im not sure how old you are but about 12 yrs ago andreas munzer past away,he was an up and coming pro,,,kinnda looked like yates only way more shredded..the coroners report stated,,,massive internal bleeding due most in part from taking 300 mgs a day of halo...at least,.
