Test my supplyPeptiAtlas has a narrow but favorable purity-focused record, led entirely by Tirzepatide with consistent identity, purity, and fill/quantity results across labs. The evidence is recent but catalog coverage is thin, so confidence is concentrated in that product; the main nuance is a 30 mg vial at 99.6% purity and +19% fill within limits.
We investigated who actually operates PeptiAtlas — corporate records, ownership trails, web infrastructure, and how its lab results break down product by product. Read the full report before you order.

About PeptiAtlas test results from Finnrick
PeptiAtlas is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 3 peptides and 11 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 PeptiAtlas peptides in this dataset are GHK-Cu (2 tests), Retatrutide (2 tests) and Tirzepatide (7 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 11 recent tests. It also includes 1 correction related to this vendor.
