most people that do all oral cycles blow up and shrink big time is why people say this, yes proper pct will help this etc. however there are alot of people out there that frankily are not commited enough to inject because they are phobic, want to take the easy way out etc. so i think the perception of people wasting away to nothing from all oral cycles has more to do with morons who dont have the discipline to juice the right way, however with all that being said imho and there is alot of anecdotal evidence to support this, people retain there gains much better if they inject as well, however i dont believe its written in stone that all orals are a waste of time.
