Finnrick analysis · Tesamorelin

TCI's Tesamorelin evidence is split, driven by a Sep 2025 purity miss at 99.423% followed by an Oct pass at 99.58% with tight fill. The small two-test record and one missing batch identifier leave the score more uncertain than stable.

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.
