Test my supplyLoti Labs' purity-focus record is strongest in Retatrutide, while Tirzepatide is uneven rather than consistently clean. Failures cluster in CJC-1295 and Semaglutide, and missing batch IDs plus dispersed purity/fill results limit lot-level confidence despite a sizeable, recent panel.
Florida filings and web infrastructure point past the Loti Labs brand to a newer operating wrapper and a wider family of related peptide storefronts. The report maps the COA lab, UK entity gap, founder-PR noise, and shared web rails behind the storefront.
Batch identification policy
Batch numbers start with LL Then have a 3 letter code for the peptide Then have a date For example LL-BPC-0526 would be BPC-157 from may of 2026 These will correspond with the published COAs on our website

About Loti Labs test results from Finnrick
Loti Labs is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 10 peptides and 40 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 Loti Labs peptides in this dataset are Tirzepatide (11 tests) and CJC-1295 (5 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 40 recent tests.
