Finnrick analysis · Tesamorelin

Repeated purity misses keep this Tesamorelin profile high-concern despite a late improving streak. The clearest red flags are Mar 4–6: 80% purity at 0.1 mg, then failed identity with 0 mg; batch IDs are inconsistent.

About Oupeptide test results from Finnrick

Oupeptide is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 11 peptides and 195 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 Oupeptide peptides in this dataset are BPC-157 (10 tests), Cagrilintide (4 tests) and CJC-1295 (3 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 195 recent tests. It also includes 4 corrections related to this vendor.

Lab correction
The previous Certificate of Analysis (COA) contained an error, incorrectly stating that the sample had a potency of **20 mg**. The actual potency of the sample is **30 mg**. A new COA has been issued and reflects the correct potency of **30 mg**.
