# Longevia Research

> Elevate your research with premium, US-synthesized research-grade peptides and biochemicals. Every batch is independently verified for ≥99% purity via third-party HPLC and LC-MS testing. Full, lot-specific Certificates of Analysis (COAs) are publicly available. Research Use Only (RUO) — strictly not for human consumption.

## About The Brand

Longevia Research is a premium research peptide supplier founded in 2024 and based in the United States. We specialize in high-purity research compounds designed for academic institutions, independent laboratories, and qualified researchers. 

The concept of "longevia" refers to the systematic optimization of one's physical appearance and biological function through controllable factors such as skincare, fitness, grooming, and diet. Our research peptides are frequently studied in the context of skin collagen synthesis, tissue recovery, body composition, and hair density — areas directly relevant to biological optimization.

## Synthesis & Quality Standards

Our non-negotiable commitment to quality rests on three pillars:
1. **US-Based Synthesis:** We utilize advanced solid-phase peptide synthesis (SPPS) in US-based, ISO-certified laboratories, ensuring precise control over sequence fidelity.
2. **Independent Testing:** We do not rely on in-house testing. Every single production batch is verified by independent, third-party laboratories using High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography–Mass Spectrometry (LC-MS). 
3. **Strict ≥99% Purity Floor:** Any batch that tests below 99% purity is immediately discarded.
4. **Lot-Traceable Transparency:** Unique lot numbers are provided with every order, tracing directly back to a publicly accessible Certificate of Analysis (COA) in our database.

## Shipping & Fulfillment

- **Location:** All orders are fulfilled locally from our US-based facilities.
- **Speed:** Standard shipping takes 3–5 business days. Expedited 2-day shipping is available and is completely free on orders over $300.
- **Processing:** Orders placed before 2 PM EST typically ship the same day.
- **Integrity:** All peptides are dispatched using validated cold-chain packaging when necessary to maintain molecular integrity in transit.

## Wholesale & Institutional Orders

We offer tiered wholesale pricing for qualified research institutions, university labs, clinical facilities, and approved wholesale accounts. Bulk orders scale with volume and still receive complete, lot-specific COA documentation. Contact our support team to apply for an institutional account.

## Important Compliance Notice

All products are sold exclusively under Research Use Only (RUO) classification. They are not approved by the FDA, EMA, or any regulatory authority for human consumption, veterinary use, or therapeutic application. Longevia Research makes no therapeutic, health, or performance claims. You do not need a medical prescription to order, as these are strict laboratory reagents.

## Refund & Returns Policy

Longevia Research operates an all-sales-final policy. Once an order ships, we do not offer refunds, exchanges, or returns for any reason, including unopened or unused product. The only exception: if an order arrives damaged in transit, is the wrong item, or does not match its documented Certificate of Analysis, we issue a free replacement (not a cash or store-credit refund) once verified.
