Remember lab assays can be forged, and whats in your product may not be related to that assay. I agree that among the top peptide suppliers (GW, Elite etc) and SARM suppliers (Southern Sarms, Sarms1 etc) they are legit. Things you can do as a consumer include starting small and checking to see if the telltale sides match the sides you experience. For example, Prami is easy, if you want to f$ck everything 24 hours a day and you feel a little queezy, its legit. For GHRP-2, if you get hungry after pinning and your hands go numb , its legit. In reality this market is close to supplements as they are not FDA regulated either. This site makes it easy to get an idea on a vendor, but remember the vendors play games here too and so do cranky members. Best of luck!

Yes there are several very good company's competition is getting fierce and they are even starting to post their lab analysis PDFs online of each new batch, find a reputable one and stick w em

you should do some research by checking the reviews and question pages of each supplier your intrested in this would be the best way of answering your question.
