Customer Reviews
The BPC-157 vials arrived in pristine condition with all vacuum seals intact. The inclusion of third-party HPLC reports directly on the site gives me the necessary confidence in their batch-to-batch consistency. It is refreshing to find a domestic source that maintains such a high standard for purity and documentation.

Jordan M., Performance Coach
The website interface is professional and the technical data provided for the CJC-1295 is highly detailed. I appreciate the focus on verified >99% purity and the fact that all items are dispatched from a US facility. It is a seamless experience from the moment of checkout to the final delivery.

Marcus S., Health Researcher
I am very impressed with the logistical speed of this operation. My order for the KLOW blend was processed and shipped within hours of placement, arriving with professional labeling and secure thermal protection. The transparency regarding their endotoxin and sterility testing sets a high bar for the industry.

Dr. Sarah L., Wellness Consultant
Finding a vendor that provides full COAs with every batch is essential for my peace of mind. The L-carnitine arrived properly lyophilized and the clarity of the product after reconstitution was excellent. Their commitment to same-day shipping makes them the most reliable source I have found for my ongoing requirements.

Elena V., Fitness Professional
The purity levels verified by the mass spectrometry profiles are exactly what I look for in a premium supplier. I have utilized their Tirzepatide across multiple cycles and the results remain consistent every single time. Vici is clearly dedicated to providing high-grade materials that meet strict quality control protocols.

Frequently Asked Questions
Product & Quality
What are peptides?
Peptides are short chains of amino acids—basically smaller versions of proteins. They play a role in nearly every biological process in your body, from signaling between cells to regulating hormones. Because of their specificity, peptides have become a major focus in scientific research.
What are your peptides used for?
All Vici peptides are sold strictly for research and laboratory use. They are not intended for human or animal consumption. We sell to researchers, labs, and qualified professionals conducting in-vitro and preclinical studies.
What purity are your peptides?
Our peptides are >99% purity, verified through third-party testing. Purity directly impacts research reliability, so we only stock peptides that meet this standard.
Do you provide Certificates of Analysis (COA)?
Yes. Every peptide we sell comes with a COA that confirms purity and identity. You can find these on each product page, or request one directly if you need a specific batch report.
How do you verify purity and identity?
All peptides undergo third-party testing using High-Performance Liquid Chromatography (HPLC) to measure purity and Mass Spectrometry (MS) to confirm molecular identity. We publish these results so you can verify exactly what you’re getting.
What makes Vici different from other suppliers?
Customer service. Everyone claims high purity, fast shipping, and competitive prices—and yeah, we have all of that. But what actually sets us apart is access to our team. Buying from Vici is like having a free research coach on demand. Some of the best minds in the peptide industry are available 24/7 to help guide your research journey. Got questions before you order? After? Six months in? We’re here.
Ordering & Payment
What payment methods do you accept?
We accept Credit Cards, Zelle, ACH bank transfer, and cryptocurrency (USDC, USDT, BTC, and ETH). We recommend reviewing our Payment Guide before checkout so you know exactly what to expect.
Who can order from Vici?

Do you ship internationally?
Not at this time. We currently only ship within the United States. International shipping may be available in the future.
(Or adjust if you do ship internationally)
How are peptides shipped?
Peptides are shipped in their lyophilized (freeze-dried) form to maintain stability. Packaging is discreet and designed to protect the product during transit.
How should I store my peptides?
Store lyophilized peptides at -20°C (freezer) in a dry, dark place. Once reconstituted, peptides should be refrigerated at 2–8°C and used within a reasonable timeframe—check the product page for specific guidance. Avoid repeated freeze-thaw cycles.
Purity & Verification
Every batch undergoes rigorous third-party testing to verify purity and identity. Certificates of Analysis (CoA) are available for all products, ensuring researchers receive laboratory-grade materials that meet strict quality standards.
