Test my supplyTCI's Purity focus record is strongest in Retatrutide, where recent reports show confirmed identity, very high purity, and only modest underfill despite missing batch identifiers. Tesamorelin is more dispersed, with an earlier purity miss followed by a pass with tight fill, so the small, thinly documented record remains uncertain.
We investigated who actually operates TCI — corporate records, ownership trails, web infrastructure, and how its lab results break down product by product. Read the full report before you order.

About TCI test results from Finnrick
TCI is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 2 peptides and 4 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 TCI peptides in this dataset are Retatrutide (2 tests), Tesamorelin (2 tests) and CJC-IPA (0 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 4 recent tests.
