COA & lab verification
Public third-party COAs surfaced on-site: each product page carries a clickable COA link (plus a dedicated /COA page), all from Freedom Diagnostics — a recognized lab. Two samples verified: BPC-157 10mg (lot MPBP004, 99.48% purity by HPLC-UV, identity confirmed by LC-MS, 10.75mg net content, chromatogram + mass confirmation, verifiable search code Midw2605050038) and Melanotan-II 10mg (lot MPMT2001, 99.126%, identity confirmed, search code Midw2602040136). Both are batch-linked, high-purity, and independently verifiable. Single-lab coverage (Freedom only, no ISO-17025/multi-lab or heavy-metals panel) holds the COA factor just below the top tier (~9/10). Notes OUTSIDE the COA factor: a still-young brand (Midwest BioResearch LLC), but with a now-verifiable reputation — 4.9/5 across 127 Trustpilot reviews and a notably responsive founder. Operations are solid: US-based, ships domestic + international with free shipping, full catalog in stock, and credit/debit card accepted alongside Zelle/CashApp/ACH/e-check. PeptidePrices is an affiliate partner (15% commission + PEPTIDEPRICES for 10% off) — disclosed per FTC; affiliate status does not influence the rating.
Our verdict on Midwest Peptide
Yes on the testing: Midwest publishes public, batch-linked Freedom Diagnostics COAs on every product page — we verified real certificates (BPC-157 99.48%, Melanotan-II 99.13%), each with identity confirmation and a verifiable search code.
Reputation is strong too — 4.9/5 across 127 Trustpilot reviews and a responsive founder. The main reservations are single-lab COA coverage (no multi-lab/ISO-17025 panel) and a still-young track record, which net an 8.5. Pricing on the GLPs is strong; accepts cards plus Zelle/CashApp/ACH; full catalog in stock. US-based; 10%-off code PEPTIDEPRICES.
More about Midwest Peptide
Midwest Peptide (Midwest BioResearch LLC) is a US-based research-peptide supplier with a genuinely public COA program: every product page links a batch-specific certificate, and there's a dedicated COA page. All testing we saw is from Freedom Diagnostics, a recognized third-party lab — we verified two real reports, a BPC-157 at 99.48% and a Melanotan-II at 99.13%, both batch-linked with identity by LC-MS and verifiable search codes.
That public, batch-level testing is what our 40% COA factor rewards, and it carries the score. Reputation backs it up: 4.9/5 across 127 Trustpilot reviews, with a notably responsive founder. The brand accepts credit/debit cards alongside Zelle/CashApp/ACH, and the full catalog is in stock. What keeps it just under the very top tier is a single testing lab (rather than the ISO-17025/multi-lab panels the 9+ vendors publish) and a still-young, largely single-platform reputation. Pricing on the GLP-1/2/3s is a real strength.
Midwest Peptide — pros & cons
Strengths
- Public, batch-linked third-party COAs on every product page (plus a dedicated /COA page) from Freedom Diagnostics — verified from two real samples: BPC-157 10mg at 99.48% (lot MPBP004) and Melanotan-II 10mg at 99.13% (lot MPMT2001), each with identity by LC-MS and a verifiable search code
- Strong, verifiable reputation — 4.9/5 across 127 Trustpilot reviews, with a founder who's notably responsive in public replies
- Strong value on the GLP-1/2/3 line — Tirzepatide 30mg at $89.99 (~$3.00/mg) and Retatrutide from $79.99 are among the better $/mg we track
- US-based (Midwest BioResearch LLC); accepts credit/debit cards plus Zelle/CashApp/ACH; ships domestic + international with free shipping; 10%-off reader code (PEPTIDEPRICES)
Watch-outs
- All public COAs come from a single lab (Freedom Diagnostics) — no ISO-17025/multi-lab panel or heavy-metals testing like the top-tier vendors
- Still a young brand: its strong reputation rests largely on one platform (127 Trustpilot reviews) rather than the multi-year, multi-source track record the very top vendors carry
Review Highlights
Positive
"Updated from 3 stars to 5 — a carrier delay on my order to Alaska wasn't the company's fault, and when founder Connor saw my review he reached out and overnighted the order to make it right. A man of his word; I'll be ordering again."
"First order — texted the number on their site with a question while checking out and someone replied within minutes. Super helpful and got my order placed."
"Order arrived super quick and was nicely packaged."
