Essential information about our research-grade peptides, quality standards, storage, shipping, and policies.
Research peptides are synthetic amino acid sequences produced for use in controlled laboratory settings. They are supplied as lyophilized powders in sealed vials, manufactured to defined purity standards, and accompanied by Certificates of Analysis documenting their identity, purity, and lot traceability. All products sold by Rhema Research Labs LLC are classified For Research Use Only and are not intended for human or animal consumption, ingestion, injection, or any diagnostic or therapeutic application.
All compounds are supplied as lyophilized (freeze-dried) powder in sealed, tamper-evident vials. Lyophilization improves stability during shipping and storage. Each vial is labeled with the compound name, lot number, quantity, and a "For Research Use Only — Not for Human Consumption" designation. Certificates of Analysis for each lot are available in the Rhema Research Labs COA Library.
Lyophilized compounds should be stored at -20°C in a dry, dark environment upon receipt at the research facility. Vials should remain sealed until opened for laboratory use. Avoid repeated freeze-thaw cycles, which can degrade compound integrity. Storage and handling protocols should be established by the receiving institution in accordance with applicable laboratory safety standards. Rhema Research Labs makes no representation regarding compound stability under storage conditions outside our control.
Purchases are restricted to qualified research professionals and institutions only. To place an order, all purchasers must create a verified account, complete our qualification process, provide business or institutional affiliation, confirm they are 21 years of age or older, and electronically sign our Terms and Conditions including the research-use-only attestation. Account approval is required before any order can be placed. Rhema Research Labs does not sell to pharmacies, compounding pharmacies, medical spas, weight-loss clinics, TRT clinics, gyms, or members of the general public for personal use. See our Terms and Conditions for full qualification requirements.
Every compound in our catalog is sourced through a verified supply chain from manufacturing partners operating under ISO and cGMP-consistent quality systems. We require independent third-party testing on select lots to confirm identity, purity, and composition. Where available, endotoxin testing results are included on Certificates of Analysis. All COAs are published in our COA Library and linked to individual product pages. We perform lot re-testing and maintain 100% traceability from manufacturer to customer.
Research Use Only (RUO) is a regulatory designation indicating that a product is intended exclusively for in-vitro laboratory research and is not approved, cleared, or authorized by the U.S. Food and Drug Administration (FDA) for any diagnostic, therapeutic, clinical, or human consumption purpose. RUO products may not be administered to, injected into, ingested by, or applied to humans or animals under any circumstances. Purchasers are solely responsible for ensuring that their use of RUO materials complies with all applicable federal, state, and local laws and regulations in their jurisdiction. See our Terms and Conditions for full details.
