Research Labs Peptides is a U.S. research-material seller for people comparing peptide suppliers before they spend money. The maker lists GLP-1 (SG) as a 5 mg, research-use-only product with 99%+ HPLC purity, and says its catalog has 60+ peptides with batch documentation. A 2025 review indexed by PubMed describes growing interest in therapeutic peptides while noting that clinical literature on some online experimental peptides remains limited.

What does Research Labs sell?
Research Labs markets peptides for in-vitro laboratory research and development. Its terms say the products are not for human or animal consumption, clinical use, diagnosis, or treatment. The seller says buyers must be qualified researchers or represent a research institution.
The listed GLP-1 (SG) image names a GLP-1 receptor agonist, 5 mg, 99%+ HPLC purity, and research use only. The seller says products are commonly lyophilized powder, meaning freeze-dried powder, and that bacteriostatic water, syringes, and other supplies are not included.
| Listed item | What the seller lists |
|---|---|
| GLP-1 (SG) | 5 mg; GLP-1 receptor agonist; 99%+ HPLC purity; research use only |
| Catalog | 60+ peptides, according to the seller |
| Documentation | The seller says every batch has a third-party certificate of analysis and HPLC and mass-spectrometry verification |
| Use | In-vitro research and development only under the seller's terms |

Is this the same as a peptide medicine?
No. A research-use label is not the same thing as an approved medicine. Research Labs describes itself as a chemical supplier, not a compounding pharmacy or outsourcing facility. Its terms also say its product descriptions and purity data are informational and not guarantees.
That distinction matters when you are trying to solve a health problem rather than plan laboratory work. The 2025 Arthroscopy review says online experimental peptides are readily available while clinical outcome research in tendon, muscle, and cartilage injury is scarce. The Cleveland Clinic discussion of research inclusion explains why study participants and study design matter when deciding whether findings apply to a particular group of people.
If your question involves your own health, a medicine you take, or a planned procedure, bring that question to a clinician. Research Labs' own terms prohibit human and animal use of its products.
How can you check a peptide supplier before paying?
A clean site and a purity percentage are only the start. For a laboratory purchase, ask for the report tied to the exact lot you would receive. The report should identify the lot, the testing method, the laboratory, and what the test actually covers. HPLC is a separation method used to assess purity. Mass spectrometry helps check molecular identity.
Research Labs says it provides a COA with every order, publishes full lab reports for every batch, and traces each vial to its production lot, raw materials, and test results. Its pages say the company uses third-party laboratories. Before payment, ask support whether the report corresponds to the exact lot in your cart and whether it covers the measurement your project needs.
- Match the lot number on the vial or label with the COA.
- Ask which laboratory issued the report and whether the report can be checked with that laboratory.
- Read the method and result, not only the headline purity number.
- Confirm storage and handling requirements for your work.
- Keep the order confirmation, lot record, and support correspondence together.
This is the same practical buyer habit used for products with incomplete product details: compare the label, the seller's claims, and the terms before you commit. Our Onyx BioLabs guide covers another peptide-shopping path and the order details to keep straight.

What is the refund policy?
Research Labs' refund policy is dated February 1, 2026. It says a full refund or replacement may be available when an order arrives damaged, has missing or incorrect items, does not meet the stated purity specification, or is lost in transit after a carrier investigation.
The seller says requests must be sent within 14 days of delivery to Info@ResearchLabs.com with an order number and photos when applicable. Opened, reconstituted, or used products are non-refundable. Orders cancelled after shipment and international customs fees, duties, or taxes are also listed as non-refundable. Approved refunds are said to take 5–7 business days and return to the original payment method.
What should you confirm before you buy?
- Confirm that your intended use fits the seller's research-only terms.
- Ask support for the lot-specific COA before payment and confirm how it matches the item you will receive.
- Check the exact variant, quantity, final checkout price, and shipping choice.
- Save the 14-day delivery date for any eligible refund request.
- For a health-related question or medicines you take, ask a clinician rather than treating a research-use product as personal care.
Research Labs lists its official site as ResearchLabs.com, support at Info@ResearchLabs.com, and phone support at (888) 898-1893 during its listed weekday hours. The seller also lists a business address on its contact page.
