Terms of Service

Welcome to Simplex Peptides. We have spent years building a reputation as one of the most trusted suppliers of research-grade peptides in the industry — and these Terms of Service reflect our commitment to operating with complete transparency and integrity.

By accessing our website, creating an account, or placing an order, you enter into a binding agreement with Simplex Peptides Ltd. We take that relationship seriously. These terms are written in plain language so you know exactly what to expect from us — and what we expect in return. If anything is unclear, our support team is always available to help.

We reserve the right to update these terms to reflect changes in our operations or applicable law. Any material changes will be communicated clearly. Your continued use of the site constitutes acceptance of the current version.

Simplex Peptides operates exclusively within the research sector. Every compound we supply is intended for in-vitro laboratory research and scientific study only — this is not a limitation we impose lightly, but a standard we uphold to protect the integrity of legitimate science and the safety of our customers.

Our catalogue is designed for qualified researchers, scientists, pharmaceutical professionals, and academic institutions who require pharmaceutical-grade reference compounds for controlled experimentation. When you purchase from us, you confirm you meet this standard and that all compounds will remain within a professional laboratory setting.

We are proud to serve institutions and independent researchers across 40+ countries. Our compounds are manufactured to the highest possible purity standards, supported by third-party HPLC and mass spectrometry certificates on every batch. We believe that research deserves real quality — not compromise.

We are committed to responsible distribution. All customers must be at least 18 years of age and possess the legal capacity to enter into a binding contract. This is not merely a formality — it is part of our broader commitment to ensuring our products are handled responsibly by qualified individuals.

We operate a verification process that may require confirmation of age or professional credentials for certain orders or customer accounts. While we aim to make this process as smooth as possible, we will not hesitate to decline orders where eligibility cannot be adequately confirmed. This protects our customers, our business, and the broader research community.

Accuracy matters to us deeply. Our product catalogue is maintained by a dedicated team of scientists and product specialists who review descriptions, concentrations, purity grades, and specifications on an ongoing basis. We invest in this process because we know that researchers rely on precise information to design and execute their studies.

Every product listing includes a Certificate of Analysis (CoA) confirming independently verified purity. We do not sell compounds we cannot verify. In the rare event of a discrepancy between listed and actual specifications, we will contact you immediately and offer a full resolution — including replacement or refund — before any item is shipped.

Should a pricing error occur, we will notify you before processing your order and give you the choice to proceed at the correct price or cancel for a full refund. We will never silently adjust an order total without your knowledge.

When you place an order with Simplex Peptides, you can do so with confidence. Our order management system is designed for speed, accuracy, and transparency. Confirmation emails are sent instantly, dispatch notifications are automated, and every stage of your order is trackable in real time through your account dashboard.

We apply a minimum order value of $155 to ensure we can maintain the quality of our packing, handling, and cold-chain logistics. This threshold is not about profit — it is about ensuring your compounds arrive in optimal condition. Rushing small parcels through our facility would compromise the standards our customers expect.

If you need to amend or cancel an order, please contact support@simplexpeptides.com within 1 hour of placement. Our team monitors support enquiries during business hours and will do everything within their power to accommodate changes before dispatch. Once an order has been handed to the carrier, our fulfilment process cannot be reversed, but our returns policy will apply.

Speed and discretion are the cornerstones of our logistics operation. Orders placed before 2:00 PM on any business day are processed and dispatched the same afternoon — a commitment we take seriously. Our warehouse team works to a strict cut-off schedule to ensure no order sits idle overnight without a very good reason.

Every shipment leaves our facility in plain, unbranded packaging with zero external indication of the contents. We understand that our customers value their privacy, and we protect it without exception. Internal packaging is designed to maintain compound integrity throughout transit, including insulated materials for temperature-sensitive items.

We partner exclusively with trusted, track-record carriers — FedEx, DHL, UPS, and regional equivalents — and provide full end-to-end tracking on every shipment. If a parcel is delayed, lost, or damaged in transit, our team will investigate and resolve the matter promptly. We do not leave our customers to fight with carriers alone.

Your satisfaction is genuinely important to us — not as a marketing phrase, but as an operational priority. We operate a 30-day return window on all unused, unopened products. Initiating a return is simple: email returns@simplexpeptides.com with your order number and we will guide you through the process within 1 business day.

Refunds are processed within 3–5 business days of receiving and inspecting the returned item. We do not delay, make excuses, or make you chase us. Once a refund is approved, it is processed immediately to your original payment method.

In the event you receive a damaged, defective, or incorrect item — which is rare given our quality controls — we ask only that you notify us within 48 hours with a photo. We will arrange a free replacement or full refund the same day, and we will cover all associated costs. No returns required for damaged items.

Simplex Peptides has invested significantly in developing original content, product documentation, educational resources, and brand identity. All website content — including product descriptions, scientific summaries, imagery, logos, and interface design — is the exclusive intellectual property of Simplex Peptides Ltd, protected under applicable copyright and trademark law.

We take a collaborative approach to the research community and welcome citations, academic references, and educational sharing of publicly available information. What we ask is that our original work is not reproduced commercially, sold, or presented as the work of others. For licensing enquiries or partnership opportunities, contact us directly.

We are transparent about our liability position because we believe customers deserve honesty. Our products are sold strictly for research purposes and are not intended for human use. Within those parameters, we stand fully behind the quality and accuracy of what we supply. Every batch is independently tested, and we provide documentation to prove it.

Our liability for any claim arising from an order is limited to the value of that order. We are not in a position to accept liability for outcomes that result from use of our products outside their stated research purpose, or for indirect losses that fall outside our reasonable control.

Nothing in these terms limits our liability for our own fraud, negligence, or any matter that cannot be legally excluded. We are a legitimate, registered business and we operate within the full scope of applicable law.

Simplex Peptides is a registered business operating in full compliance with the laws of its jurisdiction. These Terms of Service are governed accordingly, and we conduct every aspect of our operations — from procurement and manufacturing to fulfilment and customer service — within applicable legal frameworks.

In the unlikely event of a dispute, our first response is always to resolve it directly and fairly. Our customer service team is empowered to resolve complaints without bureaucratic delay. If a matter cannot be settled informally, we are open to mediation before any formal proceedings. We have no interest in adversarial outcomes — we want our customers to walk away satisfied.

We believe that clear communication builds trust. If anything in these Terms of Service raises a question, concern, or requires clarification, please do not hesitate to reach out. Our team includes people with genuine expertise in compliance, customer service, and research operations — and we are happy to discuss our policies in plain language.
