Test my supplyCrestpeptide's Purity focus record is built around Retatrutide, where recent tests show clean identity and very high purity. The evidence is still narrow and batch documentation is mostly missing, with fill results dispersed from modest underfill to overfill and no clear trajectory, so confidence is capped.
The live storefront, unreachable intake domain, and a separate lookalike competitor create an unusually messy domain trail. Corporate records, Hong Kong legal terms, an unnamed COA lab, and payment rails point to unresolved accountability behind the brand.

About Crestpeptide test results from Finnrick
Crestpeptide is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 5 peptides and 19 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 Crestpeptide peptides in this dataset are BPC-157 (3 tests), GHK-Cu (3 tests) and Retatrutide (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 19 recent tests.
