Finnrick analysis · GHK-Cu

Sparse, same-day evidence from one batch caps Coffee and Peppers' GHK-Cu more than purity concerns. BTLabs found 99.7% purity in both vials, but quantity varied from 48.8 to 41.6 mg (-17%), making fill consistency the detail to inspect.

Vendor Intelligence Report: Coffee and Peppers

Corporate searches, address captures, and domain records leave Coffee and Peppers with a thinner public entity trail than its storefront suggests. The report follows coded GLP renaming, a COA-backed label mismatch, and an affiliate funnel linking social promotion to Petratide Science.

About Coffee and Peppers test results from Finnrick

Coffee and Peppers is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 5 peptides and 38 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 Coffee and Peppers peptides in this dataset are BPC-157 (3 tests), GHK-Cu (3 tests) and Retatrutide (21 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 38 recent tests. It also includes 1 correction related to this vendor.

Finnrick data entry
Sample c8x5syc was submitted as 30mg, but physical evidence shipped by the submitter was actually 10mg. This was originally captured as 30mg, which was incorrect. Records corrected on 20 Apr to reflect the correct label claim, which modified the test score from the original 4.2 to 6.0.
