I've seen several posts concerning tren, fina, parabolin. Some claim parabolin is different and causes stronger sides than fina/tren. Are they not all the same? If not, what is the difference? Even on this site (steroid effectiveness), parabolin is rated a little different than tren/fina. I've never done any trenbolone of any kind but plan on it in my next cutting cycle in a stack including prop, primo, and winstrol. Is one better than the other if Its my first go????
