Our read on Modern Aminos
5 of Modern Aminos' 6 graded samples passed (83%), and 100% of all samples were sent in by buyers rather than by the shop.
When a sample failed, the most common reason was the lab could not confirm it was the labelled peptide (1 time).
Against the 302 shops with at least five graded tests, Modern Aminos' pass rate is at or above 77% of them, and it has more tests on record than 9% of them.
When and how Modern Aminos was tested

- Labs used
- Krause Analytical (5), Chromate (1)
- Who sent the samples
- buyers 100%

One product, a limited record
We have six independent tests for Modern Aminos, all of Retatrutide, run between June 2025 and July 2026 at Krause Analytical and Chromate. Retatrutide graded B.
None of the five vials measured for fill came in more than 5% under label, and median purity was 99.9%. Six samples of one peptide is a narrow window into a whole shop, so we rate the overall record as limited.
