Midwest Peptide publishes product-level certificates from ILS Laboratories and Freedom Diagnostics. The current review covers every in-scope catalog product, with exact provider verification and separate reporting of purity, identity, net content, and any safety panels present on each certificate.
Readers who want a single vendor whose entire injectable catalog is covered by independent, portal-verifiable third-party COAs at competitive per-vial pricing.
The GLP products are branded — GLP-3 RT is retatrutide, GLP-2 TZ is tirzepatide — and the KLOW / GLOW recovery blends are mapped to their components for $/mg comparison. Oral capsule products (BPC-157, GHK-Cu, SLU-PP-332, tesofensine) are sold but sit off the injectable-vial board. Unrelated to Midwest Compounds (midwestcompounds.com), which also prints Freedom search codes that start with Midw; the client line on the certificate is the discriminator.
Per-product ILS and Freedom Diagnostics COAs with provider verification
The current review retains 34 distinct certificates across all 30 in-scope catalog products: 21 Freedom Diagnostics reports and 13 ILS Laboratories reports. Each has an exact laboratory verification route. Results and safety panels remain specific to the individual certificate; a reported endotoxin value is not labeled a pass unless the report states that conclusion.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
