Finnrick makes sovereign health safer with free peptide tests.
More people are taking their health into their own hands, seeking treatments for longevity, weight loss, injury recovery, and more. But buying peptides online is very risky: mislabeling, contamination, wrong dosages, and zero accountability.
Finnrick works at improving safety by testing samples for purity and dosage, and publishing everything openly. We force transparency on a chaotic, high-risk market, so people can better protect themselves.
