Finnrick analysis · Retatrutide

Welon's retatrutide profile is lifted by a long clean streak after two early purity/fill misses, not by uniformly clean history. Check the 99.3%/+45% overfill result, the 99.4% purity miss, and the mostly missing batch IDs.

About Welon Peptide Solutions test results from Finnrick

Welon Peptide Solutions is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 7 peptides and 51 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 Welon Peptide Solutions peptides in this dataset are BPC-157 (7 tests), GHK-Cu (9 tests) and HGH (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 51 recent tests. It also includes 1 correction related to this vendor.

Vendor claim
Sample was incorrectly marked as having "detected" levels of endotoxins, when the amount was below the Finnrick threshold of 40 EU/sample. This has been corrected.
