Finnrick analysis

LN Peptides shows its strongest purity-focused record in Retatrutide and Tirzepatide, with mostly high-purity identity matches but recent quantity misses interrupting otherwise strong runs. Tesamorelin is the weak spot, with repeated purity failures and 0 mg identity/quantity results, while Ipamorelin and Mazdutide are positive but sparse and poorly batched.

Vendor Intelligence Report: LN Peptides

A shared WhatsApp identifier ties the peptide storefront to an older Xi'an exporter and sister domains. The report also tracks inflated age claims, crypto-only wallets, and a documented impersonation ecosystem around its Telegram reps.

About LN Peptides test results from Finnrick

LN Peptides 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 LN Peptides peptides in this dataset are Ipamorelin (2 tests), Mazdutide (1 test) and Retatrutide (12 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 2 corrections related to this vendor.
