rad150 vs rad140

did a cycle of 140 about a year ago, saw insane results, then stopped after my pct bc my job causes me to lose alot of gains (weeks without being able to go to the gym). about five months ago i did a cycle of 150 and saw subpar results and now im about to start my second week of a new 8 week 140 cycle. had anyone else experienced rad140 being way more effective then 150 or is it possible what i got was bunk?
