Research Labs Peptides is a U.S. seller of materials labeled for research use only, not personal health use. The maker says its catalog includes 60+ peptides with batch-specific Certificates of Analysis, HPLC and mass-spectrometry testing, and 99%+ purity standards; its GLP-1 (SG) label identifies a 5 mg GLP-1 receptor agonist product with 99%+ HPLC purity. If you arrived after seeing a peptide ad, the important distinction is that this seller describes itself as a chemical supplier for laboratory research, not a pharmacy or telehealth program.

What does “research use only” mean here?
Research Labs says its products are for in-vitro laboratory research and development only. Its terms say they are not intended for human or animal consumption, clinical use, diagnostic use, or use in foods, beverages, drugs, or cosmetics. The company also says purchasers confirm they are qualified researchers or represent a research institution.
That matters if your real question is about a weight-management medicine or another treatment. A research-material listing is not the same thing as a prescription pathway with a clinician and pharmacy. For a reader comparing care options, the SynergyRx GLP-1 review explains the telehealth research questions to bring to a program, while the semaglutide research review explains the clinical evidence question separately from a vendor listing.
Published peptide research covers many different molecules and settings. For example, a PubMed-indexed review of plant and aquatic peptides discusses antioxidant peptide research, while a second PubMed-indexed review of natural-source peptides describes laboratory research into ACE- and prolyl-endopeptidase-inhibitory peptides. Those broad reviews help explain why peptide research attracts interest, but they are not studies of the Research Labs catalog or its GLP-1 (SG) product.
Is Research Labs a real peptide seller?
Yes. Research Labs presents a named business, a U.S. shipping policy, terms, refund policy, privacy policy, phone support, and an email contact. The seller says it provides a third-party COA with every order and publishes full reports for every batch. It also says every compound is verified with HPLC and mass spectrometry.
For laboratory procurement, a useful document check is straightforward: match the product and batch information to the report, read what the test actually measures, and retain the document with the purchase record. A public peptide-vendor directory makes the same practical point: a report is tied to a specific sample, rather than automatically covering an entire catalog or future inventory.
| What Research Labs says | What it means for your decision |
|---|---|
| COA included with every order | Ask for the batch-specific document and keep it with the lot record. |
| 99.3% average HPLC purity across batches | This is the seller’s catalog-wide average claim; check the document for the specific batch. |
| 99%+ purity standards | The seller presents this as its quality benchmark. |
| HPLC and mass spectrometry | The seller says these methods are used to verify each compound. |
| Research use only | The terms limit products to legitimate laboratory research. |
What does the GLP-1 (SG) label say?
The visible label lists “GLP-1 (SG),” “GLP-1 Receptor Agonist,” “5 MG,” “Purity: 99%+ HPLC,” and “Research Use Only.” The label does not publish a consumer price, directions for personal use, or a clinical dosing schedule. Research Labs also says its compounds are sold individually and do not include bacteriostatic water, syringes, or other supplies.
For an adult who is actually seeking prescription weight-management care, a product label and a health-care plan answer different questions. The RNK Health review is useful for comparing a GLP-1 telehealth program’s care model with a research-material seller’s stated role.
What does Research Labs cost, and how does shipping work?
As of October 14, 2026, the Research Labs homepage lists GLP-1 (SG) at $39.99 (shown beside $59.99); confirm the current price and size at checkout. Research Labs says prices are in U.S. dollars and may change without notice.

Research Labs says lyophilized peptides are stable at room temperature during transit and should be refrigerated on receipt for long-term storage. It says a tracking number is emailed after shipment.
What is the refund policy?
Research Labs says it will issue a full refund or replacement when an order arrives damaged, has missing or incorrect items, does not meet its stated purity specification, or is lost in transit after a carrier investigation. The request must be submitted within 14 days of delivery by email with the order number and photos when applicable.
The policy says opened, reconstituted, or used products are not refundable, nor are orders cancelled after shipment or international customs fees, duties, or taxes. Approved refunds are processed in 5–7 business days to the original payment method.
What should you check before treating a peptide seller as reliable?
Use the seller’s own paperwork as the starting point, not a star rating alone. A practical laboratory checklist is:
- Confirm the seller provides a batch-specific COA for the item you are considering.
- Match the lot or batch details to the documentation.
- Read which test method and measurements the report covers.
- Keep the shipping, refund, and storage terms with the purchasing record.
- Use the seller’s stated support route for product or order questions: ResearchLabs.com lists email and phone support.
Research Labs says support is available Monday through Friday, 9 AM–5 PM PT, excluding holidays, and says it responds to email within 24 hours. The company lists a business address on its contact page.
What about side effects, medicines, and a health decision?
Research Labs does not provide medical advice and states that its research materials are not for human consumption. The FDA is the place to start when you need information about approved medicines and drug regulation rather than research materials.
If you are considering any peptide for a health purpose, ask a clinician first, especially before using it alongside prescription medicines.
Before you decide
- Confirm the exact item, batch document, price, and shipping option you need.
- Read the 14-day refund terms before payment.
- If your goal is health care rather than laboratory work, ask a clinician or pharmacist about an appropriate prescription-care route.
- Keep research-material purchases separate from health-care decisions.
