Nantong Guangyuan Chemical GYCRetatrutide
One severe -40% underfill is the main drag on an otherwise low-concern Retatrutide lab profile. Later tests recovered with high purity and mostly modest fill variance, though some batch identifiers are missing.
A clone-site trail uses a near-match Telegram handle, fake verification badge, and backdated review wall to impersonate GYC. The report separates the real Nantong trading entity from fraud infrastructure across domains, DNS, forum posts, and channel history.

About Nantong Guangyuan Chemical GYC test results from Finnrick
Nantong Guangyuan Chemical GYC is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 3 peptides and 46 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 Nantong Guangyuan Chemical GYC peptides in this dataset are Retatrutide (19 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 46 recent tests.
