About our Research Peptides
Rejuven8 Peptides supplies high-purity, research-grade peptides for laboratory and analytical study. Our catalog spans the growth hormone axis, GLP and incretin metabolic pathways, tissue regeneration and repair, melanocortin signaling, neuropeptides, and cellular longevity cofactors. Every compound is USA-made and independently verified for identity and purity before it is released.
Each product ships with batch-specific documentation, so researchers can confirm identity, purity, sterility, and net peptide content for the exact vial in hand. Orders placed before 3PM EST ship the same day. All products are supplied strictly for research use only.
Quality & Testing Standards
- Independent HPLC verification: Every batch is tested by a third-party U.S. laboratory (Freedom Diagnostics) for identity and ≥99% purity before release.
- Batch-specific COA: Every vial links to the certificate of analysis for its exact production batch, so you can verify the lot in hand.
- Proper handling and storage: Lyophilized compounds are kept dry and cool for maximum stability in transit.
Frequently Asked Questions
What does “Research Use Only” (RUO) or "Research Peptides" mean?
RUO products are not for human or veterinary use, diagnostics, or drugs. They’re sold solely for laboratory, in-vitro, and R&D applications.
What analytical tests do you run?
Typically HPLC for purity and LC-MS or MS for identity. Some lots may include additional tests (water content, TFA content, endotoxin) where noted.
What purity are your peptides?
Purity varies by product and batch and is typically specified on each product page. A Certificate of Analysis (CoA) reflects HPLC purity for the lot you receive.
How should I store lyophilized peptides?
Keep sealed and dry. Short term: 2–8 °C (refrigerated). Long term: −20 °C is recommended.
How long will it take for my order to ship after processing?
Our team always ships orders within 1 business day if there are no unexpected delays with our facility or shipping providers.
What does “lyophilized” mean?
Freeze-dried powder form that improves stability and shelf life under proper storage.
What's the typical vial size/fill?
See each product page for mass (e.g., 5 mg, 10 mg). Vial fill volume is not indicative of mass—refer to the labeled content.
