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 buy products through normal customer channels. We send them to independent labs. 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.
