Going to have to disagree here. This seems to be the case in the supplement market quite often, but I've had lots of experience with research chemicals, and I think a lot of people share my opinion when I say that not all research chemicals are created equal. Particularly with SARMs and peptides - you get what you pay for.
Cheap SARMs are cheap for a reason and pricey SARMs are pricey for a reason. What type of results you want is up to you.
I do agree that you should try both; order a round from GWP and a round from SS. But I can assure you that youll come to the same conclusion that I did - nothing compares to the quality and purity of Sarmssearch. Or you could save yourself some time and money and go with them for the get go, your call
