hey guys... i was wondering if doing a primo only cycle would benefit me...i did some research and saw that it was usually stacked with other stuff, but i'm curious if it is worth trying .... the problem is that i can only take stuff with very low detection times cuz i get tested in college so primo sounds the most appealing to me at this time..if u all have any suggestions please let me know.....thanks for any input.....also does primo sacrafice speed and give u a lot of size or not really
