Why TriedRx exists
The peptide market has an accountability problem. Vendors make claims about purity and potency that consumers can't verify. “99% pure” is printed on labels that have never seen the inside of a lab. Prices vary 400% for the same compound. And most review sites take money from the brands they rank.
We aggregate published lab data, vendor-published certificates of analysis, and community sentiment from public forums. We publish every result — including the failures. We don't take vendor money. We don't run ads. If a vendor scores well, it's because their product tested well. Period.
Independent. Unbiased. Unsponsored.
