Most of the peptides in the market today are trash. It like everything else demands means suppliers get greedy and produce inferior or fake sutff to try and increase profits, meet demands and compete. Back in the days when we had a few and new suppliers like ergo-pep whos stuff was the real deal. Now you'd be lucky to find anything potent. I 100% dont trust a single source unless its a pharma company used by corporations and we know those dont come cheap.
