Test my supplyPeptide Sciences stopped trading on 6 Mar 2026, and the current buyer risk is a post-shutdown impersonation ecosystem rather than ordinary vendor performance. Across 130 Finnrick lab tests, the historical record is mixed at a 60% pass rate: Semaglutide and GHK-Cu look stronger, while CJC-1295 and Retatrutide require heightened skepticism. The full report traces the P-Sciences lookalike through WHOIS, registry searches, payment artifacts, complaint records and stale coupon infrastructure.
The dossier follows a post-shutdown P-Sciences lookalike through WHOIS, a Fort Lauderdale mail-drop, Florida registry searches and crypto payment rails. It also separates stale coupon funnels, QR Peptides and peptides.gg from the original brand.

Peptide Sciences is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 10 peptides and 132 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 Peptide Sciences peptides in this dataset are Semaglutide (15 tests), BPC-157 (13 tests) and Melanotan II (10 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 132 recent tests.
