Batch identification policy

Batch Identification Policy Batch/lot numbers are printed on each unit near the expiration date or on the bottom/side of the package. Customers can verify the batch by checking the printed lot code and contacting support with their order ID, product name, and photos if the code is missing, damaged, or unclear.

Sample authentication guidance

Sample Authentication Guidance Authentic samples arrive in sealed packaging with intact tamper-evident seals, consistent CellX branding, clear labeling, and a readable batch/lot code. Do not use any sample if packaging is opened, relabeled, damaged, missing a lot code, or differs from the product photos.

About Maurits Bio test results from Finnrick

Maurits Bio 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 Maurits Bio 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.
