The certificate reads well — a named chemist, a lot, a measured 10.06mg — but the lab behind it is a year-old site whose verification page does nothing, and the company behind the vendor is a mailbox number with no entity name and no review record. Until the lab lookup works, treat the document as vendor-hosted.
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.

Not awarded. How to check: The company's registered name (LLC, Inc., s.r.o. …) and a street address appear on the vendor's own Contact, About or Terms pages — not only a brand name, a city, or hidden page markup.
Not awarded. How to check: Compare any on-site review score or badge with the independent platform; check whether the vendor only takes, or pushes you toward, payment rails you cannot dispute; check FDA and BBB records. Awarded unless one of these is on record.

Direct Peptides appears in 1 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
The Reddit record is old and negative: 'Direct-peptides are a scam' (2021), 'Be wary of Direct-Peptides, took my money' and 'A bit skeptical about Direct Peptides' — nothing recent and nothing positive visible. Combined with the non-functional lab verification on our review, proceed with caution.
The poster says the vendor was fine in earlier orders and then, in 2021, was not.
A vetting thread.
How this was read: Google's Reddit results for "Direct Peptides 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 Direct Peptides. Scores are computed from published evidence and do not read partner status.
As of 19 September 2026, Direct Peptides scores 6/10 on our verification rubric and has Trustpilot profile removed. 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 Direct Peptides legit?" page at /guides/is-direct-peptides-legit.
Horizon Analytical certificate for BPC-157 10mg lot DPS-1676478 (report 1027437, analysis 13 Aug 2026) reporting measured quantity 10.06mg on a 10mg label and purity 99.41% by UPLC/MS, with the chemist named. Catalog, prices and certificates viewable without an account; sized pricing (TB-500 10mg $99, read 18 Sep 2026). Street address published: 700 Smith St #61070, Houston, TX 77002.
The certificate says 'searchable via horizonanalytical.com', but the lab's Verify COA form did nothing when we submitted the report number on 19 Sep 2026 — no request was sent — and the form's own example lot number uses this vendor's 'DPS-' prefix. The lab's domain was registered in October 2025 and its site prints no address. We found no shared infrastructure between vendor and lab, so we are not calling it captive, but the lab-side verification does not work today. Trustpilot profile REMOVED. No legal entity name printed; the address is a numbered mailbox suite. GLP products are sold as 'GLP-1 SM', 'GLP-2 TZ' and 'GLP-3 RT' without the compound stated, so they are excluded from our price index.
