Batch Records and Janoshik COAs — Verify Every Remy Peptides Lot

Key Facts

What We Cover

Remy Peptides publishes research reference material on peptides studied in in-vitro laboratory applications, organised around a retatrutide-led library. The flagship subject is Retatrutide (LY-3437943)—a synthetic peptide that simultaneously engages GLP-1, GIP, and glucagon receptor pathways, and one of the most studied next-generation compounds in metabolic research—documented in prefilled-pen and lyophilized-vial formats. The UAE-facing format reference is maintained on the Retatrutide UAE formats page.

Coverage extends well beyond the metabolic flagship into six research categories. Retatrutide and GLOW are documented as prefilled pens in a pH-balanced, bacteriostatic solution that removes the reconstitution step; the remaining compounds are documented as lyophilized research vials, reconstituted with bacteriostatic water — the mixing math lives on the reconstitution calculator.

Across the archived records, each documented batch was manufactured under controlled GMP-adjacent conditions and underwent a full analytical workup—retatrutide batches were independently HPLC-verified by Janoshik Analytical, and non-retatrutide vials were documented at >99% HPLC purity.

Every compound covered here is discussed strictly for in-vitro laboratory research purposes. None is intended, marketed, or approved for human or veterinary diagnostic or therapeutic use in any jurisdiction, and Remy Peptides does not sell, supply, distribute, or broker research materials.

Quality Assurance

Independent verification is the cornerstone of the Remy Peptides quality framework. Each archived Retatrutide batch was submitted to Janoshik Analytical—a widely recognized third-party laboratory specializing in peptide and pharmaceutical-grade compound analysis—for full HPLC purity testing: 30mg pen RETP002 at 99.262%, 20mg pen RET-20-C-2604-001 at 99.841%, 10mg vial RET-20-V-2604-001 at 99.741%, and 40mg vial RT-40-V-001 at 99.692% (sterility-tested). No COA has been published for the 10mg pen. Only batches that met or exceeded the ≥99.2% purity threshold were published to this archive. Certificates of Analysis are published on-site for every archived lot number. Non-retatrutide research vials—across the tissue-repair, copper, mitochondrial, growth-hormone-secretagogue, and other targeted categories—are documented at >99% HPLC purity. For a plain-English explanation of HPLC purity, assay, endotoxin, TFA, and heavy-metals fields, see the Peptide COA Guide. Full batch-level proof for the archived batches lives in the COA Library; for the explainer layer with methodology and FAQ per documented format, see the Lab Results hub.

The stability parameters recorded on those certificates assume an unbroken 2–8°C chain: refrigerated storage, protection from light, and no freeze-thaw cycling. Our peptide stability and storage guide sets out how those conditions map onto laboratory handling.

The point of keeping this record public is verifiability: third-party analytical results, published certificates, and a documented chain from batch ID to test date, so any purity figure cited across this site can be traced back to the report it came from.
