About OROS Research
OROS Research Science Without Shortcuts™
OROS Research, headquartered in Cary, North Carolina, is a trusted supplier of high-purity, U.S.-made research peptides. We support scientists, independent laboratories, and institutions with rigorously tested compounds and a commitment to quality, transparency, and compliance. Our mission is to elevate the standard of research — while maintaining accessiblity through cost effective pricing.
What OROS Research Means “OROS Research” is derived from the Greek word for “mountain” or “peak” — a symbol of ascension, clarity, and mastery. It reflects our mission to help raise the standard of research by operating at the peak of scientific quality and integrity.
Not All Peptides Are Created Equal
OROS Research is one of the few research peptide suppliers in the United States offering genuinely U.S.-manufactured peptides — formulated in our California-based partner facility under controlled, cGMP-aligned processes and supported by detailed Certificates of Analysis (COAs)..
Unlike many online vendors who import cheap peptides from overseas and simply repackage them as “Made in the USA,” we uphold full transparency and scientific integrity from formulation to fulfillment. Choose OROS for authentic sourcing, verified purity, and real research results.
Why Researchers Trust OROS Research
Made in the USA
Our peptides are genuinely formulated and manufactured in California—not imported and repackaged. We maintain full control over our supply chain to ensure authenticity and uncompromising quality.
cGMP-Aligned & ISO-Based Quality Systems
Every batch is produced in our California-based partner facility operating under strict cGMP and ISO aligned quality protocols to ensure consistency, purity, and reliability. Manufacturing takes place within an ISO Class 5 cleanroom environment utilizing laminar flow systems, designed to maintain extremely low particulate levels and protect product integrity throughout the production process. These controlled conditions support sterile handling, precise formulation, and contamination control at every stage of manufacturing.
From raw material verification through final formulation, purification, lyophilization, vialing, and sealing, each stage of production follows rigorous quality standards to ensure every batch meets the expectations of high-quality research materials. Maintaining a clean, tightly controlled manufacturing environment is fundamental to our process and reflects our commitment to quality, safety, and consistent, reliable research outcomes.
Third-Party Tested
Our OROS Research-use-only peptides are tested by independent, U.S.-based laboratories—not overseas providers. Each Certificate of Analysis (COA) is verifiable directly through the testing lab and includes lot numbers, compound identity, purity, net content, conformity results (multi-vial testing), and confirmation of endotoxin absence to support reliable research outcomes. We are also expanding our testing protocols to include heavy metal analysis and sterility testing, with reporting expected to begin in April 2026.
Reliable Research
As the demand for high-quality, U.S. made peptides grows, OROS is committed to consistency at every level. We’ve built long-term infrastructure to ensure reliable access, dependable batch quality, and secure fulfillment so researchers can move forward with confidence
Frequently Asked Questions
How do the products arrive?
All peptides are shipped via UPS in secure, tamper-evident packaging. Products are supplied in a lyophilized (freeze-dried) form and housed in sterilized, sealed vials, a format designed to ensure maximum stability during storage and transit.
Because lyophilized peptides are inherently stable, cold packs are not required for shipping, and the compounds can withstand normal temperature fluctuations encountered during transit. Our shipping boxes and internal packaging are engineered to withstand impact, shield products from direct sunlight, and protect them from environmental exposure throughout the delivery process.
A Certificate of Analysis (COA) is provided for each product and is accessible both on the individual product pages and within our COA Library. Each COA includes the lot number, purity results, net content, and endotoxin status, providing full batch-level transparency.
How should products be stored?
We recommend storing lyophilized peptides in a cool, dry environment, away from direct light and humidity. For long-term preservation, freezer storage is ideal. Once reconstituted, peptides should be refrigerated and used within your laboratory’s established research guidelines.
What are endotoxins and why do you test for them?
Endotoxins are contaminants that can interfere with research results and cell-based studies. We test each batch to confirm the absence of endotoxins, ensuring our peptides meet strict purity and safety standards for reliable in vitro research.
What is your return or exchange policy?
Due to the sensitive nature of our products, all sales are final. We do not accept returns or exchanges. If you receive a damaged, defective, or incorrect item, please contact us within 48 hours of delivery so we can make it right.
How long does shipping take?
Orders are processed and shipped within 1–2 business days, with the majority of orders shipping the same business day when payment is received before 3:00 PM Eastern Time.
We ship orders Monday through Friday, excluding holidays or unforeseen circumstances such as severe weather, carrier disruptions, or other factors outside of our control.
All domestic orders are shipped via UPS, with Ground, 2-Day, and Overnight delivery options available at checkout. Orders over $150 qualify for free UPS 2-Day shipping. Please note that selecting an express shipping option does not expedite order fulfillment and only affects carrier transit time once the order has shipped.
Shipments to Hawaii and Alaska are fulfilled via USPS Priority Mail. UPS is unable to deliver to PO Boxes.
All orders include complimentary full-value shipping insurance to protect against loss, damage, or theft during transit.
Do you offer international shipping?
At this time, we only ship within the United States. We do not support international orders or freight forwarding services.
Can I cancel or modify my order?
Orders cannot be modified or canceled once they have been paid for. Please double-check your shipping address and product selection before finalizing your purchase.
