I have used their GW- total crap. I also ordered aromasin. I never used it bc I didn't wanna fuck up my body. I just got some ancillaries from a reputable company instead. This is the only RC company I have used so far. IMO it's always better to get your ancillaries elsewhere. There are plenty of sources that are reliable w proven products. As far as sarms and GW- you need to do your research. I am putting in an order w Pure Essence soon- trusted people on this forum stand by them
