Finnrick analysis

Alchemy Peptides' current purity-focus record is strong but narrow, with Retatrutide showing clean identity, very high purity, and near-label fill in the available tests. Because all evidence is same-day, vendor-sent, and lacks batch IDs, consistency over time and broader catalog performance remain uncertain.

Vendor Intelligence Report: Alchemy Peptides

Corporate registry searches, a Corona mailbox address and peer-to-peer payment rails leave Alchemy with limited public recourse signals. The report traces a sister storefront, a Peptide Sciences terms remnant, a pharmacy COA trail and code-bearing influencer posts.

About Alchemy Peptides test results from Finnrick

Alchemy Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 1 peptide and 2 tests, including ratings, observed price signals, recent test dates, and correction history where available.

Finnrick ratings are calculated from published sample data using the selected rating standard. The default standard evaluates purity, dose accuracy, and label quality, then adjusts low-volume results so small sample counts do not appear more certain than the data supports.

The most visible Alchemy Peptides peptides in this dataset are Retatrutide (2 tests). Use the peptide table above to compare the current Finnrick rating, price per mg, and sample volume for each peptide.

Recent tests and corrections are shown below when available. Samples may be acquired by Finnrick directly or submitted through Finnrick testing programs; the goal is to make safety and supply-chain evidence easier to evaluate than vendor marketing claims alone. This page currently lists 2 recent tests.
