Peptide PartnersRetatrutide
Peptide Partners Retatrutide has a notable caveat despite a strong purity-focus signal: a Nov 2025 purity miss at 99.11% and fill swings to -21% and +22%. Recent tests show a rebound with identity passes and documented batches.

All vial labels have a Batch Id that can be reconciled against the various COAs for Purity/Assay, Endotoxin, Heavy Metals, or Sterility testing at
Sample authentication guidance
Our 3mL vials have a 1.25" x 0.75" white, BOPP label. At the top of the label is the full logo with the 'P Vial' symbol on the left, followed Peptide Partners, and underneath it says "CONNECTING THE GLOBAL RESEARCH COMMUNITY." Underneath the logo is a line identifying the molecule and weight. Underneath that is the word 'Batch' followed by an identification code. At the bottom of the label it reads "Research Use Only"

About Peptide Partners test results from Finnrick
Peptide Partners is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 8 peptides and 88 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 Peptide Partners peptides in this dataset are Retatrutide (25 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 88 recent tests.
