Everything researchers ask us before placing their first order.
Research Use Only peptides are manufactured and sold strictly for laboratory research, analytical testing, and scientific investigation. They are not drugs, dietary supplements, or medical products, and they are not intended for human or animal consumption, injection, or any therapeutic, diagnostic, or cosmetic use.
No. RUO peptides have not been evaluated or approved by the FDA or any other regulatory body for safety, efficacy, or use in humans or animals. They have not undergone clinical trials and carry no assurance of biological safety outside a controlled laboratory setting.
No. RUO peptides are not intended for personal use of any kind, including self-administration, bodybuilding, weight loss, anti-aging, or wellness purposes. Any such use falls entirely outside the product's labeled intent and is not supported, endorsed, or sanctioned by Cathrex Labs.
Our RUO peptides are intended for licensed researchers, laboratories, universities, and research institutions conducting legitimate in vitro or preclinical research. Customers must have the appropriate scientific background, facilities, and institutional oversight (e.g., IRB/IACUC approval where applicable) to handle these materials safely and appropriately.
Each peptide ships with a Certificate of Analysis (CoA) detailing purity (typically via HPLC), molecular weight confirmation (via mass spectrometry), and lot-specific data. Safety Data Sheets (SDS) are also available for proper handling and storage guidance.
Cathrex Labs is not responsible for any use of RUO peptides outside their labeled research purpose. By purchasing, customers affirm that the product will be used solely for legitimate laboratory research by qualified personnel, in compliance with all applicable federal, state, and local laws. Any use for human or animal consumption, self-experimentation, or unauthorized purposes is strictly prohibited and undertaken at the sole risk of the purchaser.
No. Cathrex Labs does not provide dosing, administration, or usage instructions for human or animal application under any circumstances. Any dosing-related information referenced in scientific literature pertains strictly to preclinical research protocols, not personal use.
Domestic shipping within specific regulated regions is standard. International orders depend heavily on local import laws regarding research chemicals, and the buyer assumes full compliance responsibility.
Recommendations vary by peptide, but general best practices include storing lyophilized peptides at −20°C or lower for long-term stability, reconstituting only in a controlled lab environment using appropriate solvents as specified, avoiding repeated freeze-thaw cycles, and using appropriate PPE.
