Vendor Intelligence Report: Liberty Peptides

Archived pages and Delaware filings put Liberty’s storefront timeline at odds with its corporate record. The report traces a hidden BioBoost Labs source-code link and a COA trail through Horizon Analytical with accreditation and vendor-overlap concerns.

About Liberty Peptides test results from Finnrick

Liberty Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 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 Liberty Peptides peptides in this dataset are BPC-157 (4 tests), CJC-1295 (4 tests) and Retatrutide (6 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. It also includes 1 correction related to this vendor.

Corrections

Finnrick data entry
CJC-1295 (Liberty Peptides): identity corrected from Fail against CJC-1295 (no DAC) to Pass against CJC-1295 (DAC); purity (90.8%) and quantity (8.73 mg) are now reported. The CJC variant was inconsistently communicated to the lab by Finnrick, and the lab ran its initial analysis against the incorrect variant. The vendor raised a formal objection, and Finnrick initiated an investigation. The lab then issued an updated analysis based on the original measurements.
