2. API Supply for Licensed 503A Compounding Pharmacies
US Peptide Clinic maintains a legally distinct buyer category for licensed 503A compounding pharmacies that purchase compounds as active pharmaceutical ingredients (APIs) for compounding into finished drug preparations pursuant to valid patient-specific prescriptions. This section applies exclusively to accounts verified as active 503A pharmacies.
What this category covers:
- A 503A compounding pharmacy holds a state pharmacy license and compounds drugs for identified individual patients under valid prescriptions from licensed practitioners;
- APIs purchased from US Peptide Clinic by a 503A pharmacy are incorporated into compounded preparations — they are not dispensed in their original form;
- The finished compounded drug is the regulated product; the API is a starting material in that process.
What this category does NOT cover:
- 503B outsourcing facilities (a different and more regulated framework requiring direct FDA registration and cGMP compliance — US Peptide Clinic does not supply 503B facilities under this model);
- Clinics, wellness centers, or medical practices purchasing compounds for direct patient administration without a 503A pharmacy intermediary — this remains prohibited under the RUO framework;
- Any form of retail dispensing of purchased APIs without compounding.
The 503A pharmacy's exclusive responsibilities include:
- Verifying and maintaining valid patient-specific prescriptions for every compounded preparation incorporating these APIs;
- USP <797> sterile compounding compliance and/or USP <795> non-sterile compliance, as applicable;
- State board of pharmacy recordkeeping for API sourcing, lot traceability, and dispensing;
- DEA compliance for any APIs that trigger controlled substance regulations in the compounded form;
- Patient counseling, labeling, and dispensing in accordance with state pharmacy law.
US Peptide Clinic is an API supplier only. It does not participate in, oversee, or assume any responsibility for the compounding, prescription review, or dispensing process. The presence of a valid COA and MSDS does not substitute for the pharmacy's own quality control obligations under USP and state law.
3. No FDA Approval
The FDA has not evaluated or approved any of the compounds offered on this platform for safety or efficacy in human or animal applications. This includes peptides that may be referenced in published clinical literature — academic research does not constitute FDA approval.
In 2026, the FDA significantly escalated enforcement of the research chemicals sector, issuing over 40 warning letters in the first quarter of the year alone and referring six cases for criminal investigation under misbranding statutes of the Federal Food, Drug, and Cosmetic Act (FD&C Act). This regulatory environment underscores the following:
- Selling, distributing, or administering research peptides to human subjects without proper regulatory authorization constitutes misbranding and may be prosecuted as a federal criminal offense;
- The "Research Use Only" label does not create a legal safe harbor for buyers who use products for human consumption;
- FDA enforcement is increasingly focused on the entire supply chain — suppliers, distributors, and end buyers alike.
US Peptide Clinic maintains complete transaction records and cooperates fully with all regulatory authorities. Buyers whose accounts show evidence of non-research use will be terminated and referred to appropriate authorities.
4. No Medical Advice
Nothing on this platform — including product descriptions, Certificates of Analysis (COAs), dosing or concentration specifications, blog content, scientific references, or any communication from US Peptide Clinic staff — constitutes medical advice, clinical guidance, or a recommendation for use in any human or animal health application.
Specifically:
- Product descriptions describe the compound's chemical identity, research-grade purity, and laboratory characteristics — not therapeutic benefits;
- References to published scientific literature are provided for research context only and do not imply endorsement or clinical recommendation;
- COA data represents analytical testing results under controlled laboratory conditions and does not assess safety or efficacy for any use in living organisms;
- No employee, contractor, or agent of US Peptide Clinic is authorized to provide medical, clinical, or therapeutic advice of any kind.
Persons seeking medical treatment or advice should consult a licensed and qualified healthcare professional.
5. Buyer's Sole Responsibility
The buyer assumes full, exclusive, and non-delegable responsibility for:
- Determining whether the receipt, possession, storage, handling, and use of any purchased compound is lawful in the buyer's jurisdiction prior to placing any order;
- Obtaining and maintaining all required federal, state, and local licenses, registrations, and permits;
- Complying with all applicable OSHA laboratory safety standards, EPA disposal regulations, DEA requirements (where applicable), and institutional biosafety protocols;
- Ensuring that research involving purchased compounds is conducted only by trained scientific personnel in appropriately equipped facilities;
- The safe storage of compounds in accordance with the product's Material Safety Data Sheet (MSDS/SDS) and storage specifications;
- The proper disposal of compounds and related waste materials in accordance with applicable environmental regulations.
US Peptide Clinic expressly disclaims all liability for any harm, loss, penalty, or regulatory action arising from the buyer's failure to fulfill these responsibilities.
6. Disclaimer of Warranties
To the fullest extent permitted by applicable law, US Peptide Clinic provides all products and platform content "as is" and "as available" without warranty of any kind, express or implied, including but not limited to:
- Implied warranties of merchantability;
- Fitness for a particular purpose;
- Non-infringement of third-party intellectual property rights;
- Accuracy, completeness, or currency of any scientific data presented;
- Suitability of compounds for any specific research application.
Purity and identity specifications are as reported on the Certificate of Analysis issued for the specific lot at the time of testing. Compound stability over time depends on appropriate storage conditions maintained by the buyer after receipt. US Peptide Clinic makes no warranty regarding compound stability, shelf life, or research outcomes.
7. State Law Variation & Jurisdictional Compliance
U.S. regulations governing research compounds vary significantly by state. As of 2026, at least 14 states have enacted requirements that exceed federal minimums, creating a complex jurisdictional patchwork. Examples include:
- California: Requires California-specific disclosure statements on MSDS documentation accompanying all research compound shipments (effective January 2025 per AB 1887);
- New York, Texas, Illinois: Have enacted specific licensing requirements for certain classes of research compounds;
- Multiple states: Restrict or prohibit possession of certain peptide categories regardless of their research designation.
US Peptide Clinic ships only within the continental United States. Buyers are solely responsible for verifying that their order is legal in their state and locality prior to checkout. We do not provide legal advice regarding state-specific regulations. Buyers in jurisdictions with heightened restrictions are strongly advised to consult legal counsel before placing any order.
Orders that appear inconsistent with applicable state law may be declined at our sole discretion without notice.
8. Age Restriction
This platform is strictly intended for authorized business representatives who are at least 18 years of age. By registering and placing orders, you represent that you are an adult and are acting in a professional business capacity on behalf of a legally registered organization.
Any individual found to be under the age of 18 will have their account immediately terminated and any associated orders cancelled. US Peptide Clinic will not knowingly provide products or platform access to minors under any circumstances.
9. Regulatory Changes
The regulatory landscape governing research compounds, peptides, and research-use chemicals is actively evolving. Federal and state agencies including the FDA, DEA, and various state health departments continue to issue new guidance, rulemaking, and enforcement actions that may affect the legal status of specific compounds.
US Peptide Clinic does not guarantee the ongoing legal availability of any product. We reserve the right to withdraw any product from sale at any time without notice if we determine that changed regulatory circumstances warrant such action.
Buyers who have placed orders that are affected by regulatory changes will be notified and provided with options for order modification or cancellation. It is each buyer's ongoing responsibility to monitor applicable regulations in their jurisdiction.
This disclaimer was last reviewed in May 2026. It will be updated as necessary to reflect material regulatory changes. Continued use of the platform constitutes acceptance of the then-current version of this disclaimer.
