A very large, very positive live review record attached to an unnamed laboratory. The certificates exist and carry batch numbers, but nothing lets a reader confirm who produced them. That gap is the whole story here.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

Midwest Peptide appears in 4 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.

How this was read: Google's Reddit results for "Midwest Peptide reddit" on 29 September 2026 — thread titles, subreddit, dates and the text visible in search. We did not read every comment, so a gist says what a thread is and what its visible text says, not what it concludes. Threads in a vendor-run or ranking-site subreddit, and listicles or coupon posts in unrelated subreddits, are labelled as such. None of this is an input to the score; the rubric reads evidence, not opinions.
Affiliate partner; we earn a commission on Purgo orders. We earn nothing from Midwest Peptide. Scores are computed from published evidence and do not read partner status.
As of 5 September 2026, Midwest Peptide scores 7/10 on our verification rubric and has 4.9 (316 reviews). The trust assessment — who runs it, whether a certificate can be checked with the lab, the payment rail, and what we flagged — is on our "Is Midwest Peptide legit?" page at /guides/is-midwest-peptide-legit.
4.9 across 259 Trustpilot reviews. Certificates with batch numbers viewable pre-purchase without an account. Full basket with sized pricing (BPC-157 10mg $39.99, TB-500 10mg $49.99). Legal entity disclosed: Midwest BioResearch LLC, Mission, KS.
The lab (Precision Mass Spec) appears only on the certificate, never in page text; the certificate (lot MPBP007-MWP-BPCW-0821) reports 11.04mg vs 10mg label but offers no lab-side lookup. No street address. GLP-class products sold under house codes with the identity only in FAQ text; the BPC-157 page contradicts itself on the peptide's length.
