Searches for GLP peptides mix two very different worlds: licensed medical providers, and suppliers of research-grade compounds for the laboratory. This page is only about the second. Orion Peptides is a US-based research peptide supplier, headquartered in Los Angeles and shipping from South Carolina. It supplies semaglutide, tirzepatide and retatrutide as lyophilized research compounds. They are not medicines and are not for human use.
What to check before choosing a US research supplier
| Check | What good looks like |
|---|---|
| Testing | A third-party COA for each batch, with HPLC purity and an identity test |
| Lab named | The testing laboratory is identified on the report |
| Net content | Measured mg per vial, not just the label figure |
| US fulfilment | Ships from a US address, with tracking |
| Clear research framing | No claims about effects in people, use, or outcomes |
| Support | A real contact route and published policies |

Why research-only framing matters
In 2025–2026 the FDA issued warning letters to several peptide sellers. A recurring theme was that a “research use only” label doesn’t hold up if the rest of the site points to human use. For a lab, a supplier that keeps its pages strictly scientific is a lower-risk supplier to rely on.
