I've never used sus, I also do either enanthiate or propionate. Todays aas market is definitely different from before. Even 3-4 years ago you could atleast choose from multiple solid sources, now there are only a few. If you trust your source and aren't getting any gains then I would contact them and ask if they could send you different gear. Also you could start a thread and ask if anyone has tried the jelfa sus250 from x source. Having said that though to be honest 4 weeks is still a bit early to be expecting anything noticable. Make sure diet is optimized as well, duh lol. Give it some time, if by the end of week 6 still nothing, then I'd contact the source.
