| Testing & COAs | Third-party tested; a COA is published with every batch on a public COA page. Not yet independently graded (e.g. Finnrick). |

| Shipping | Free shipping on every U.S. order. Fast domestic dispatch. |
| Sourcing | U.S.-based (Mission, Kansas). |
| Catalog | Broad: BPC-157, TB-500, GLP-1 / GLP-2 / GLP-3 (sema, tirz, reta), CJC-1295, GHK-Cu, MOTS-C, NAD+, Semax, Selank, Tesamorelin, PT-141, blends, and research supplies. |
| Compliance | Labeled and sold strictly for research use only. |
Two things stand out immediately. First, free shipping on every order — no minimum threshold, which is rare in this space and removes the usual "spend $200 to skip the shipping fee" friction. Second, a third-party Certificate of Analysis published for every batch, kept on a public COA page rather than hidden behind a support request. For a research buyer, batch-level COA access is the single most useful transparency signal a vendor can offer.
The brand is U.S.-based out of Mission, Kansas, the catalog is broad enough to cover most common research compounds, and the customer record is clean — no FDA warning letters, no contamination reports, and a 4.9★ Trustpilot rating.
Midwest Peptide is a newer company. The COAs are third-party and published openly, but the brand has not yet been independently lab-graded by a verification service like Finnrick, and its reputation currently rests mostly on Trustpilot rather than the broader Reddit/forum consensus that backs longer-established vendors. None of that is a red flag — it's simply less corroborating data than the most-vetted names carry. We rate on evidence, so Midwest sits as a strong, clean option that we'll re-score upward once independent batch testing confirms the published COAs. See our ranking methodology for how we weigh this.
