The review

What it says, what we checked, what the lab found.

Budget pricing on the recovery peptides, but the dearest retatrutide on the board at 118 dollars for 10 mg, a five-day delivery estimate, and certificates that are not tied to a lot or a named lab. Finnrick holds 9 samples, 5 passing, and the three most recent, from June to August 2026, all failed.

Orders take about 5 days to arrive . Across the 12 compounds it lists, its median price sits at 1.54x the market median per milligram. It earns 2 of 7 transparency checks in full.

5 of 9 independent samples published by Finnrick passed its standard of 99.5% purity and a measured quantity within 35% of the label. Every result is in the test history below with a link to the source. That adds up to 48.3 of 100, position 24 of 24.
